Preface

ABOUT AUTOMATED EXTERNAL DEFIBRILLATION

The following considerations and guidelines apply when using the LIFEPAK® 20e defibrillator/ monitor as an automated external defibrillator (AED).

Operator Considerations

The LIFEPAK 20e defibrillator/monitor, when in AED mode, is a semiautomatic defibrillator that uses a patented Shock Advisory System™. This software algorithm analyzes the patient’s electrocardiographic (ECG) rhythm and indicates whether or not it detects a shockable rhythm. The LIFEPAK 20e defibrillator/monitor in AED mode requires operator interaction to defibrillate the patient.
The LIFEPAK 20e defibrillator/monitor in AED mode is intended for use by personnel who are authorized by a physician/medical director and have, at a minimum, the following skills and training:
• CPR training.
• AED training equivalent to that recommended by the American Heart Association.
• Training in the use of the LIFEPAK 20e defibrillator/monitor in AED mode.

Indications

The AED mode is to be used only on patients in cardiopulmonary arrest. The patient must be unconscious, pulseless, and not breathing normally before using the defibrillator to analyze the patient’s ECG rhythm.
In AED mode, the LIFEPAK 20e defibrillator/monitor is not intended for use on pediatric patients less than 8 years old.

Contraindications

None known.

Preface

ABOUT DEFIBRILLATION THERAPY

Operator Considerations

A direct current defibrillator applies a brief, intense pulse of electricity to the heart muscle. The LIFEPAK 20e defibrillator/monitor delivers this energy through disposable electrodes, standard paddles or internal paddles applied to the patient’s chest.
Defibrillation is only one aspect of the medical care required to resuscitate a patient with a shockable ECG rhythm. Depending on the situation, other supportive measures may include:
• Cardiopulmonary resuscitation (CPR)
• Administration of supplemental oxygen
• Drug therapy
Successful resuscitation is related to the length of time between the onset of a heart rhythm that does not circulate blood (ventricular fibrillation, pulseless ventricular tachycardia) and defibrillation. The American Heart Association has identified the following as critical links in the chain of survival from cardiac arrest:
• Early access
• Early CPR by first responders or bystanders
• Early defibrillation
• Early advanced life support
The physiological state of the patient may affect the likelihood of successful defibrillation. Thus, failure to resuscitate a patient is not a reliable indicator of defibrillator performance. Patients will often exhibit a muscular response (such as jumping or twitching) during an energy transfer. The absence of such a response is not a reliable indicator of actual energy delivery or device performance.
Preface

Indications

Defibrillation is a recognized means of terminating certain potentially fatal arrhythmias, such as ventricular fibrillation and symptomatic ventricular tachycardia. Delivery of this energy in the synchronized mode is a method for treating atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia and, in relatively stable patients, ventricular tachycardia.

Contraindications

Defibrillation is contraindicated in the treatment of Pulseless Electrical Activity (PEA) such as idioventricular or ventricular escape rhythms, and in the treatment of asystole.

Preface

ABOUT NONINVASIVE PACING

A noninvasive pacemaker is a device that delivers an electrical stimulus to the heart, causing cardiac depolarization and myocardial contraction. The energy is delivered through large adhesive electrodes placed on the chest. In addition to noninvasive pacing, other supportive measures may be necessary.
Among other factors, it is recognized that successful pacing of a patient is related to the length of time between the onset of a dysrhythmia and the initiation of pacing. Rapid pacing and prompt follow-up care are essential. The physiologic state of the patient may affect the likelihood of successful pacing or of skeletal muscle activity. The failure to successfully pace a patient is not a reliable indicator of pacemaker performance. Similarly, the patient’s muscular response to pacing is not a reliable indicator of energy delivered. Refer to the booklet, Noninvasive Pacing: What You Should Know for further information.

Indications

Noninvasive pacing is indicated for symptomatic bradycardia in patients with a pulse.

Contraindications

Noninvasive pacing is contraindicated for the treatment of ventricular fibrillation and asystole.

ABOUT SPO2 MONITORING

A pulse oximeter is a noninvasive device that checks the saturation of oxygen in arterial blood (SpO
). It uses an optical sensor that directs light through the patient’s finger and then measures
2
the received light with a detector. This received light is translated into a saturation percentage and is displayed as an SpO
reading.
2

Indications

A pulse oximeter is indicated for use in any patient who is at risk of developing hypoxemia.

Contraindications

None known.

ABOUT ECG MONITORING

The ECG (electrocardiogram) is a recording of the electrical activity of the heart. ECG monitoring allows for identification and interpretation of cardiac rhythms or dysrhythmias and calculation of heart rate. The ECG is obtained by placing either electrodes or paddles on the patient and allows the heart’s electrical activity to be monitored and recorded.

ABOUT ETCO2 MONITORING

The end-tidal carbon dioxide (EtCO2) monitor is a capnograph device that uses non-dispersive infrared spectroscopy to continuously measure the amount of CO the amount present at the end of exhalation (EtCO
). The sample is obtained by the side stream
2
method and can be used with intubated or nonintubated patients. Respiration rate is also measured and displayed in breaths per minute.

Preface
The EtCO to assess the patient at all times; do not rely solely on the EtCO
monitor is a tool to be used in addition to patient assessment. Care should be taken
2
monitor.
2

Indications

EtCO2 monitoring is used to detect the level of expired CO2. It is used for monitoring breathing efficacy and treatment effectiveness in acute cardiopulmonary care, for example, to determine if
adequate compressions are being performed during CPR or to rapidly detect whether an endotracheal tube has been placed successfully.

Contraindications

None known.

The following paragraphs provide additional information about Area 7.
Monitoring Area—Heart Rate
The LIFEPAK 20e defibrillator/monitor displays a heart rate between 20 and 300 beats per minute (bpm). A heart rate symbol flashes with each beat. If the heart rate is below 20 bpm or pacing is enabled, the screen displays dashes (– – –). Heart rates above 300 bpm do not yield valid systole tones and the displayed heart rate will not be valid. The heart rate indicator is a tool to be used in addition to patient assessment. Care should be taken to assess the patient at all times and to not rely solely on the displayed heart rate.
WARNING!
Failure to detect a change in ECG rhythm.
Heart rate meters may continue to count the internal pacing pulses during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely on heart rate meter alarms. Keep pacemaker patients under close surveillance.
QRS detection is essential for using the digital heart rate display, systole tone, synchronized cardioversion, and noninvasive demand pacing. The QRS detector in the LIFEPAK 20e defibrillator/monitor selectively detects QRS complexes. It discriminates against most noise, muscle artifact, T-waves, and other spurious signals.
The QRS detect algorithm automatically adjusts itself to the amplitude of the QRS complexes. Changing the gain of the ECG has no effect on QRS detection. For optimum QRS detection performance, use the lead with the greatest QRS amplitude.

CONNECTING TO POWER

The LIFEPAK 20e defibrillator/monitor and the optional CodeManagement Module operate on AC (line) power or their internal Lithium-ion batteries. You can switch from battery to AC power or AC power to battery while the device is on and in use by plugging in or unplugging the AC power cord.
When the CodeManagement Module is connected to the LIFEPAK 20e defibrillator, one power cord is used to power both the defibrillator and the CodeManagement Module.
IMPORTANT: The AC power cord is the safety disconnect mechanism. Maintain clear access to all connections at all times.
WARNING!
Possible defibrillator shutdown.
When operating on battery power, adhere to battery maintenance and replacement intervals discussed in the Battery Performance and Life section to prevent possible defibrillator shutdown. If the defibrillator shuts down without warning, or if a LOW BATTERY: CONNECT TO AC

AC Operation

When the LIFEPAK 20e defibrillator/monitor operates on AC power, the AC Mains LED illuminates. When the defibrillator is not in use, the battery charge is best maintained if the power cord is connected to an AC outlet and the defibrillator is turned off.
Note: When the CodeManagement Module is attached to the defibrillator, the green LED on the CodeManagement Module and the AC Mains LED on the defibrillator are both illuminated while the device is connected to AC power.

BATTERY OPERATION

The LIFEPAK 20e defibrillator/monitor and the CodeManagement Module each have an internal battery. Battery operation for the defibrillator is explained below. Battery operation for the CodeManagement Module is explained on page 2-23.

LIFEPAK 20e Defibrillator/Monitor Battery

The internal Lithium-ion battery is rechargeable and is intended for use when AC power is unavailable or when the device is being used in a portable manner, such as in transport. The defibrillator automatically switches to battery power when the power cord is disconnected from an AC outlet or from the defibrillator.
2-20 LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Basic Orientation
A new, fully charged battery provides approximately 140 360-joule discharges, 110 minutes of pacing, or approximately 210 minutes of continuous monitoring before the defibrillator turns off. When one flashing red bar appears in the battery status indicator and the
CONNECT TO AC POWER
message appears on the screen, immediately plug the power cord into
LOW BATTERY:
an AC outlet to continue use and begin recharging the battery. If low battery messages frequently appear, the battery may need to be replaced. Contact Physio-Control Technical Support or qualified service personnel for assistance.
Connect the defibrillator to AC power after each use to recharge the battery. Typically, new fully depleted batteries recharge for 4 hours to regain full capacity. Partially depleted batteries recharge for a time period equivalent to the time the defibrillator was in use. For example, if the defibrillator was used one hour, the required recharge time will be approximately one hour.
New batteries or batteries that have been stored for an extended time should be recharged before they are used. Connect the defibrillator to an AC power outlet to bring the battery to full charge.
Note: The LIFEPAK 20e defibrillator/monitor is intended to operate with the internal battery installed. In the event of a missing or faulty battery, when plugged into AC power, the device will still operate and the service light will illuminate at power on. Contact Physio-Control Technical Support or qualified service personnel for assistance.
Battery Performance and Life
Several factors can contribute to the Lithium-ion battery’s performance and life cycle, including:
1 The defibrillator’s use for assisting patients (“on time” and shocks). 2 The defibrillator’s use when the battery is at minimum capacity (low battery condition). 3 The battery’s normal self-discharge rate and the energy used by defibrillator self-tests.
To maximize battery performance and life, plug the defibrillator/monitor into an AC outlet to recharge the battery whenever the defibrillator/monitor is not in use. As a reminder, you can set up the LIFEPAK 20e defibrillator/monitor to sound a series of warning beeps, identified as
LOSS ALERT
, whenever the defibrillator is turned off and not plugged into an AC outlet (refer to
AC
the "General Setup Menu," page 8-4).
Note: While the defibrillator is plugged into AC power, the battery condition is periodically checked. If the battery is missing or is unable to charge, a service LED illuminates the next time the defibrillator is turned on. To check the battery capacity, perform the defibrillation function test (refer to "Maintenance and Testing Schedule," page 7-2).
Note: Even when properly maintained, the internal rechargeable Lithium-ion battery should be replaced every two years.
Battery Status Indicator
The battery status indicator approximates the amount of operating time available under battery power for the LIFEPAK 20e defibrillator/monitor. It does not indicate battery status for the CodeManagement Module. The battery status indicator appears on the screen after the defibrillator is turned on. (See Figure 2-13, page 2-10.) The number of illuminated bars indicates the battery capacity and how long the battery will provide power to the defibrillator.
2 Basic Orientation
A new, fully charged battery will show four green bars, indicating the battery is charged to 100% capacity. As battery charge and battery capacity decreases, the indicator bars decrease incrementally. One flashing red bar indicates a very low or empty battery. Refer to Table 2-2.

It is important to note that both charge (voltage) and capacity are factors contributing to the battery status indicator’s display. For example, the battery status indicator displays two green bars when a new battery has 100% capacity and has been charged to 50%. However, an older battery that is 100% charged and only has 50% capacity also displays two green bars. The following demonstrates this example.
This battery may either be low in capacity or low in charge as follows:
• For a new battery with 100% capacity, this symbol indicates 50% charged (low in charge).
• For an older battery with 50% capacity, this symbol indicates 100% charged (low in capacity).

ECG Monitoring Warning

WARNING!
Possible misinterpretation of ECG data.
The frequency response of the monitor screen is intended only for basic ECG rhythm identification; it does not provide the resolution required for diagnostic and ST segment interpretation. For diagnostic or ST segment interpretation, or to enhance internal pacemaker pulse visibility, attach the ECG cable. Then print the ECG rhythm in diagnostic frequency response (DIAG).

Selecting ECG Lead and Size

There are two methods for selecting or changing the ECG lead. Both methods are available on your LIFEPAK 20e defibrillator/monitor. The leads available depend on the ECG cable (3-wire or 5-wire) connected to the device.

Monitoring ECG with Paddles Accessories

Anterior-lateral Placement
Anterior-lateral placement is the only placement that should be used for ECG monitoring with paddles accessories.
1 Place either the
or + therapy electrode or the apex paddle lateral to the patient’s left nipple in
the midaxillary line, with the center of the electrode in the midaxillary line, if possible. Refer to
Figure 3-1.
Figure 3-1 Anterior-lateral Placement
2 Place the other therapy electrode or sternum paddle on the patient’s upper right torso, lateral
to the sternum and below the clavicle as shown in Figure 3-1.
Special Placement Situations
When placing therapy electrodes or standard paddles, be aware of the special requirements in the following possible situations.
Obese Patients or Patients with Large Breasts — Apply therapy electrodes or standard paddles to a flat area on the chest, if possible. If skin folds or breast tissue prevent good adhesion, it may be necessary to spread skin folds apart to create a flat surface.
Thin Patients — Follow the contour of the ribs and spaces when pressing the therapy electrodes or standard paddles onto the torso. This limits air spaces or gaps under the electrodes and promotes good skin contact.
Patients with Implanted Pacemakers — If possible, place therapy electrodes or standard paddles away from internal pacemaker generator.
Patients with Implanted Defibrillators — Apply therapy electrodes or standard paddles in the anterior-lateral position and treat this patient as any other patient requiring emergency care.
Paddles Monitoring Procedure
To monitor using therapy electrodes or standard paddles:
1 Press 2 Prepare the patient’s skin:
ON.
• Remove excessive chest hair as much as possible. Avoid nicking or cutting the skin. If possible, avoid placing therapy electrodes or standard paddles over broken skin.
• Clean and dry the skin.
• Do not use alcohol, tincture of benzoin, or antiperspirant to prep the skin.

ECG Electrode Requirements
Electrode quality is critical for obtaining an undistorted ECG signal. Always check the date code on electrode packages for the Use By date before applying the electrodes to a patient. Do not use electrodes with expired Use By date codes. Disposable electrodes are intended for a single use.
For best ECG monitoring results, use silver/silver chloride (Ag/AgCl) electrodes. These electrodes provide a rapid display of post-defibrillation ECG.
Leads Off Messages
If an electrode or lead wire disconnects during ECG monitoring, the monitor emits an audible alarm and displays a leads off message. The ECG trace becomes a dashed line
. The alarm and
messages continue until the electrode or lead wire is replaced.
Color Coding for ECG Leads
The lead wires and the electrode snaps for the patient ECG cable are color coded according to AHA or IEC standards as listed in Table 3-1.

Monitoring Patients with Internal Pacemakers
The LIFEPAK 20e defibrillator/monitor typically does not use internal pacemaker pulses to calculate the heart rate. However, the monitor may detect internal pacemaker pulses as QRS complexes. This may result in an inaccurate heart rate display.
Smaller amplitude internal pacemaker pulses may not be distinguished clearly. For improved detection and display of internal pacemaker pulses, turn on the internal pacemaker detector, and/ or connect the ECG cable, select an ECG lead, and print the ECG in diagnostic frequency response.
Large amplitude pacemaker pulses may overload the QRS complex detector circuitry so that no paced QRS complexes are counted. To help minimize ECG pickup of large unipolar pacemaker pulses when monitoring patients with internal pacemakers, place ECG electrodes so the line

between the positive and negative electrodes is perpendicular to the line between the pacemaker generator and the heart.
The LIFEPAK 20e defibrillator/monitor annotates internal pacemaker pulses with a hollow arrow
on the display and the printed ECG if this feature is configured or selected
ON. False
annotations of this arrow may occur if ECG artifacts mimic internal pacer pulses. If false annotations occur, you may deactivate the detection feature using the Options/Pacing/Internal Pacer menu (refer to Figure 2-7). Also refer to the "Pacing Setup Menu" in Table 8-9. Patient history and other ECG waveform data, such as wide QRS complexes, should be used to verify the presence of an internal pacemaker.

Troubleshooting Tips for ECG Monitoring

SpO2 Warnings and Cautions

WARNINGS!
Shock or burn hazard.
Before use, carefully read these operating instructions, the sensor and extension cable directions for use, and precautionary information.
Shock or burn hazard.
Other manufacturers’ oxygen transducers may cause improper oximeter performance and invalidate safety agency certification. Use only oxygen transducers approved for this product.
Inaccurate pulse oximeter readings.
Do not use a damaged extension cable or one with exposed electrical contacts. Never use more than one extension cable between the pulse oximeter and the sensor.
Inaccurate pulse oximeter readings.
Do not use a damaged sensor. Do not alter the sensor in any way. Alterations or modifications may affect performance and/or accuracy.
Inaccurate pulse oximeter readings.
Sensors exposed to ambient light (such as sunlight, surgical lights, or bilirubin lamp) when incorrectly applied to a patient may exhibit inaccurate saturation readings. Securely place the sensor on the patient and check the sensor’s application frequently to help ensure accurate readings.
LIFEPAK 20e Defibrillator/Monitor Operating Instructions 3-9

Monitoring
WARNINGS! (CONTINUED)
Inaccurate pulse oximeter readings.
Severe anemia, significant blood levels of carboxyhemoglobin or methemoglobin, elevated levels of total bilirubin, intravascular dyes that change usual blood pigmentation, excessive patient movement, venous pulsations, electrosurgical interference, exposure to irradiation and placement of the sensor on an extremity that has a blood pressure cuff, intravascular line or externally applied coloring (such as nail polish) may interfere with oximeter performance. The operator should be thoroughly familiar with the operation of the oximeter prior to use.
Inaccurate pulse oximeter readings.
The pulsations from intra-aortic balloon support can be additive to the pulse rate. Verify patient’s pulse rate against the ECG heart rate.
Skin injury.
Prolonged, continuous use of a sensor may cause irritation, blistering, or pressure necrosis of the skin. Check the sensor site regularly based on patient condition and type of sensor. Change the sensor site if skin changes occur. Do not use tape to hold the sensor in place, as this may cause inaccurate readings or damage to the sensor or skin.
Possible strangulation.
Carefully route patient cabling to reduce the possibility of patient entanglement or strangulation.
CAUTION!
Possible equipment damage.
To avoid damaging the extension cable or the sensor, hold the connectors, rather than the cables, when disconnecting.

When to Use a Pulse Oximeter

A pulse oximeter is a noninvasive tool that checks the saturation of oxygen in arterial blood (SpO
) and is not to be used as an apnea monitor or as a replacement or substitute for ECG
2
based arrhythmia analysis. It is used for monitoring patients who are at risk of developing hypoxemia. If a pulse oximeter is not used, the only indications of hypoxemia are a patient’s dusky skin, nail beds, and mucous membranes, accompanied by restlessness and confusion. These indications are not conclusive, however, and do not appear until after the patient has developed hypoxemia. Pulse oximetry is to be used in addition to patient assessment. Care should be taken to assess the patient at all times and to not solely rely on the SpO
reading. If a
2
trend toward patient deoxygenation is indicated, blood samples should be analyzed using laboratory instruments to completely understand the patient’s condition.

How a Pulse Oximeter Works

A pulse oximeter sensor directs light through a fleshy body site (usually the finger or earlobe). The sensor sends light from the emitting diodes to the receiving detector as shown in Figure 3-4. Oxygen saturated blood absorbs light differently as compared to unsaturated blood. The pulse oximeter translates the amount of light received into a saturation percentage and displays an SpO
reading. Normal values typically range from 95% to 100% at sea level.

Figure 3-4 How a Pulse Oximeter Works
The quality of the SpO2 reading depends on correct sensor size and placement, adequate blood flow through the sensor site, patient motion, and exposure to ambient light. For example, with very low perfusion at the monitored site, readings may read lower than core arterial oxygen saturation. Test methods for accuracy are available by contacting your local Physio-Control representative.
3 Monitoring

SpO2 Monitoring Considerations

Each oximeter sensor is applied to a specific site on the patient. Use the following criteria to select the appropriate sensor:
• Patient weight
• Patient perfusion to extremities
• Patient activity level
• Available application sites on the patient’s body
• Sterility requirements
• Anticipated duration of monitoring
To help ensure optimal and accurate performance:
• Use a dry and appropriately sized sensor.
• Keep the sensor site at the same level as the patient’s heart.
• Apply the sensor according to the Directions for Use provided with the sensor.
• Observe all warnings and cautions noted in the sensor’s Directions for Use.
The sensors are sensitive to light. If excessive ambient light is present (such as sunlight, surgical lights, or bilirubin lamp), cover the sensor site with an opaque material to block the light. Failure to do so could result in inaccurate measurements.
If patient movements present a problem, consider the following possible solutions:
• Be sure the sensor is secure and properly aligned.
• Use a new sensor with fresh adhesive backing.
• If possible, move the sensor to a less active site.
Note: Wrapping the sensor too tightly or using supplemental tape to hold the sensor in place may cause inaccurate measurements.

Monitoring

SpO2 Monitoring Procedure

The defibrillator controls power to the pulse oximeter. When the defibrillator is turned on, the oximeter turns on and performs a self-test that requires up to 10 seconds. When the defibrillator is turned off, the oximeter also turns off.
To conserve battery power, the pulse oximeter goes into “sleep mode” when not in use. Sleep mode is activated within 10 seconds of disconnecting the sensor. During sleep mode, the screen does not display SpO or a patient signal. The oximeter performs the self-test when it returns from sleep mode to active mode.

contamination of the sensor.
Expiratory Upstroke. In the normal waveform, the rising phase (II–III segment) is usually steep. When this segment becomes less steep, CO
delivery is delayed from the lungs to the sampling
2
site. The causes of this delay can be physiologic or mechanical and include bronchospasm, obstruction of the upper airway, or obstruction (or kinking) of an endotracheal tube (ETT).
Expiratory Plateau. The plateau of the waveform, which represents the remainder of expiration (III-IV segment), should be nearly horizontal. The end of the plateau represents the EtCO
value.
2
Upward slanting of the expiratory plateau occurs when there is uneven emptying of the alveoli. Similar to the diminished slope of the Expiratory Upstroke, this pattern can occur in asthma, chronic obstructive pulmonary disease (COPD), partial upper-airway obstruction, or partial mechanical obstruction such as a partially kinked ETT.
Inspiratory Downstroke. The fall to baseline (IV-V segment) is a nearly vertical drop. This slope can be prolonged and can blend with the expiratory plateau in cases of leakage in the exhale portion of the breathing circuit. The peak EtCO
value (IV) is often not reached. Relying on the
2
numeric end-tidal value without observing the breathing waveform may obscure the presence of a leak.

GENERAL THERAPY WARNINGS AND CAUTIONS

WARNINGS!
Shock hazard.
The defibrillator delivers up to 360 J of electrical energy. When discharging the defibrillator, do not touch the paddle electrode surfaces or disposable therapy electrodes.
Shock hazard.
If a person is touching the patient, bed, or any conductive material in contact with the patient during defibrillation, the delivered energy may be partially discharged through that person. Clear everyone away from contact with the patient, bed, and other conductive material before discharging the defibrillator.
Shock hazard.
Do not discharge the defibrillator into the open air. To remove an unwanted charge, change the energy selection, select disarm, or turn off the defibrillator.
Possible fire, burns, and ineffective energy delivery.
Do not discharge standard paddles on top of therapy electrodes or ECG electrodes. Do not allow standard paddles (or therapy electrodes) to touch each other, ECG electrodes, lead wires, dressings, transdermal patches, etc. Such contact can cause electrical arcing and patient skin burns during defibrillation and may divert defibrillating energy away from the heart muscle.
Possible defibrillator shutdown.
When operating on battery power, adhere to battery maintenance and replacement intervals discussed in the Battery Performance and Life section to prevent possible defibrillator shutdown. If the defibrillator shuts down without warning, or if a
LOW BATTERY: CONNECT TO AC POWER
message appears on the monitor screen, immediately connect the AC power cord to an outlet.
Possible skin burns.
During defibrillation or pacing, air pockets between the skin and therapy electrodes may cause patient skin burns. Apply therapy electrodes so that entire electrode adheres to skin. Do not reposition the electrodes once applied. If the position must be changed, remove and replace with new electrodes.
Possible skin burns and ineffective energy delivery.
Therapy electrodes that are dried out or damaged may cause electrical arcing and patient skin burns during defibrillation. Do not use therapy electrodes that have been removed from foil package for more than 24 hours. Do not use electrodes beyond expiration date. Check that electrode adhesive is intact and undamaged. Replace therapy electrodes after 50 shocks.
Possible interference with implanted electrical device.
Defibrillation may cause implanted devices to malfunction. Place standard paddles or therapy electrodes away from implanted devices if possible. Check implanted device function after defibrillation.
CAUTION!
Possible equipment damage.
Prior to using this defibrillator, disconnect all equipment from the patient that is not defibrillator­protected.

THERAPY ELECTRODE AND STANDARD PADDLE PLACEMENT

The following paragraphs describe therapy electrodes and standard paddles placement, including special placement situations.

Anterior-lateral Placement

Anterior-lateral placement allows for ECG monitoring, defibrillation, synchronized cardioversion, and noninvasive pacing.
1 Place either the
or + therapy electrode, or apex paddle lateral to the patient's left nipple in
the midaxillary line, with the center of the electrode in the midaxillary line, if possible. Refer to
Figure 4-1.
Figure 4-1 Anterior-lateral Placement
2 Place the other therapy electrode or sternum paddle on the patient’s upper right torso, lateral
to the sternum, and below the clavicle as shown in Figure 4-1.

Anterior-posterior Placement

Anterior-posterior is an alternative position for noninvasive pacing, manual defibrillation, and synchronized cardioversion, but not for ECG monitoring or automated defibrillation. The ECG signal obtained through electrodes in this position is not a standard lead. (For pediatric applications, see "Pediatric Defibrillation," page 4-21.)
4Therapy
1 Place either the
or + therapy electrode over the left precordium as shown in Figure 4-2. The
upper edge of the electrode should be below the nipple. Avoid placement over the nipple, the diaphragm, or the bony prominence of the sternum if possible.
2 Place the other electrode behind the heart in the infrascapular area as shown in Figure 4-2.
For patient comfort, place the cable connection away from the spine. Do not place the electrode over the bony prominences of the spine or scapula.

Special Placement Situations

When placing therapy electrodes or standard paddles, be aware of the special requirements in the following possible situations.
Synchronized Cardioversion
Alternative anterior-posterior placements for cardioversion of supraventricular arrhythmias include:
• Place the
or + therapy electrode over the left precordium and the other electrode on the
patient’s right posterior infrascapular area
– or –
•Place the
or + therapy electrode to the right of the sternum and the other electrode on the
patient’s posterior left infrascapular area.
Obese Patients or Patients with Large Breasts
Apply therapy electrodes or standard paddles to a flat area on the chest, if possible. If skin folds or breast tissue prevent good adhesion, it may be necessary to spread skin folds apart to create a flat surface.
Thin Patients
Follow the contour of the ribs and spaces when pressing the therapy electrodes onto the torso. This limits air spaces or gaps under the electrodes and promotes good skin contact.
Patients with Implanted Pacemakers
If possible, place therapy electrodes or standard paddles away from the internal pacemaker generator to help prevent damage to the pacemaker. Treat the patient like any other patient requiring care. When operating the defibrillator in AED mode, pacemaker pulses may prevent advisement of an appropriate shock, regardless of the patient’s underlying rhythm.
Patients with Implanted Defibrillators
Apply therapy electrodes or standard paddles in the anterior-lateral position and treat this patient as any other patient requiring emergency care. If defibrillation is unsuccessful, it may be necessary to try alternate electrode placement (anterior-posterior) due to the insulative properties of implanted defibrillator electrodes.

Manual Defibrillation Warnings

WARNINGS!
Possible fire, burns, and ineffective energy delivery.
Precordial lead electrodes and lead wires may interfere with the placement of standard paddles or therapy electrodes. Before defibrillation, remove any interfering precordial lead electrodes and lead wires.
Shock hazard.
Conductive gel (wet or dry) on the paddle handles can allow the electrical energy to discharge through the operator during defibrillation. Completely clean the paddle electrode surfaces, handles, and storage area after defibrillation.
Possible patient skin burns.
During defibrillation, air pockets between the skin and standard paddles can cause patient skin burns. Completely cover paddle electrode surfaces with fresh conductive gel and apply 11.3 kg (25 lb) of pressure per paddle during discharge.
Possible paddle damage and patient skin burns.
Discharging the defibrillator with the standard paddle surfaces shorted together can pit or damage the paddle electrode surface. Pitted or damaged paddle surfaces may cause patient skin burns during defibrillation. Discharge the defibrillator only as described in these operating instructions.
Therapy
4Therapy
Possible burns and ineffective energy delivery.
A gel pathway on the skin between the standard paddles will cause defibrillating energy to arc between paddles and divert energy away from the heart muscle. Do not allow conductive gel (wet or dry) to become continuous between paddle sites.
Possible damage to defibrillator and defibrillator shutdown.
When used in conjunction with another defibrillator to deliver more than 360J, one or both defibrillators may be damaged and shutdown may occur due to excessive currents. Avoid simultaneous discharge from both defibrillators and maintain a backup defibrillator in case one or both defibrillators shut down. If the defibrillator shuts down, take the defibrillator out of service and contact a qualified service technician.
To use the LIFEPAK 20e defibrillator/monitor primarily as a manual defibrillator, configure the defibrillator before placing the defibrillator in use. To configure the defibrillator, refer to Section 8.

Impedance

LIFEPAK biphasic defibrillators measure the patient's transthoracic impedance and automatically adjust the defibrillation waveform voltage and current duration to meet the needs of the individual patient.
Impedance is measured whenever the defibrillator is charged. To ensure correct patient impedance readings, you should always charge the defibrillator when the standard paddles (hard paddles) or QUIK-COMBO electrodes are in contact with the patient's chest.
If the standard paddles are in the paddle wells or touching face to face (shorted paddles) when the defibrillator is charged, the defibrillator limits the available energy to 79 joules This prevents damage to the internal circuits, in the event the energy is discharged while the hard paddles are still in the paddle wells or shorted together. If the defibrillator is charged to 80 joules or more and energy is discharged when the hard paddles are seated in the paddle wells, the display indicates the selected energy available and the automatic printout annotates time, date and Shock 1 79 J.
LIFEPAK 20e Defibrillator/Monitor Operating Instructions 4-15
©2006-2013 Physio-Control, Inc.
Therapy
If the defibrillator is charged to 80 joules or more with paddles in the paddle wells, and then the paddles are removed and placed on a patient, the defibrillator continues charging to the selected energy and defibrillation may be completed as usual. When charging the defibrillator with the paddles on the patient’s chest, the defibrillator automatically adjusts the waveform voltage and current duration based on the patient's impedance. It is important to understand that this automatic adjustment does not occur when the defibrillator is charged with the paddles seated in the paddle wells.
When the paddles or QUIK-COMBO electrodes are on the patient's chest when the defibrillator is charged and the defibrillator measures an impedance of 15 ohms or less, the defibrillator disarms the capacitor and automatically recharges to a lower energy setting. When this condition occurs, the
LOW IMPEDANCE-RECHARGING message appears on the display. When charging is
complete, defibrillation may be completed as usual.

Defibrillation Procedure

You can configure the LIFEPAK 20e defibrillator/monitor to automatically sequence energy levels. Refer to "Manual Mode Setup Menu," page 8-5.
1 Press

CPR Metronome

When CPR is required during cardiac arrest, the CPR metronome provides audible prompts that guide the user to deliver CPR with proper timing in accordance with the 2010 American Heart Association and European Resuscitation Council CPR guidelines.
CPR Metronome Warnings
WARNING!
CPR Delivered When Not Needed.
The metronome sounds do not indicate information regarding the patient’s condition. Because patient status can change in a short time, the patient should be assessed at all times. Do not perform CPR on a patient who is responsive or is breathing normally.
Note: The CPR metronome is a tool to be used as a timing aid during CPR. Assess the patient at all times and provide CPR only when indicated. Provide CPR according to your training and protocols.
How the CPR Metronome Works
The metronome provides audible “tocks” at a rate of 100/minute to guide the rescuer in performing chest compressions. The metronome also provides audible ventilation prompts (either a tone or verbal “ventilate”) to cue the rescuer when to provide ventilations. The metronome prompts the rescuer to perform CPR at the selected compression to ventilation (C:V) ratio.
Age-Airway Considerations
The default C:V ratio for the metronome (in both AED and Manual modes) is Adult - No Airway (30:2) because most patients in cardiac arrest are adults who have an initially unsecured airway. In Manual mode, the user can choose the most appropriate C:V ratio based on the patient’s age and current airway status. The Age-Airway selection determines the C:V ratio of the metronome sounds. The default C:V ratios are shown in Table 4-2.
Table 4-2 Default Age-Airway C:V Ratios in Manual Mode
Age-Airway C:V Ratio
Adult - No Airway* 30:2
Adult - Airway** 10:1
Youth - No Airway*** 15:2

* No Airway = No artificial airway in place ** Airway = Advanced artificial airway in place *** Youth = Pre-pubescent child
Note: The compression-to-ventilation ratio selections can be set up according to local medical protocols. For more information, refer to "CPR Metronome Setup Menu," page 8-8.

Activating and Deactivating the Metronome
To activate the CPR metronome in Manual mode:
Note: The CPR metronome cannot be activated during noninvasive pacing.
Note: If the VF/VT alarm is on, it is suspended when the metronome is on to prevent false
VF/VT alarms. If other vital sign alarms activate when the metronome is on, the visual indicators occur, but the alarm tone is suppressed until the metronome is deactivated.
The metronome provides “tocks” and ventilation prompts continuously until it is deactivated. To stop the metronome, select recorded in the CODE SUMMARY Event Log when CPR metronome is turned ON or OFF and when the Age-Airway setting is changed. To adjust the volume of the metronome, press
OPTIONS, select ALARM VOLUME, and change the VOLUME.
Note: If all Age-Airway selections are set to the same C:V ratio (for example, Adult - No
Airway, Adult - Airway, Youth - No Airway, and Youth - Airway all set to 10:1), the CPR metronome always provides “tocks” and ventilation prompts at the set ratio for both AED mode and Manual mode. In this situation, the CPR Metronome menu does not appear when the

Remote Synchronization Procedure

WARNINGS!
Possible lethal arrhythmia.
Ventricular fibrillation may be induced with improper synchronization. The hospital’s biomedical engineering staff should perform synchronization delay measurements on the system, as a whole, to ensure that the 60 ms limit for synchronization delay is not exceeded, per requirements as specified in AAMI DF2 (1996). Always confirm proper placement of the sense markers on the ECG.
Possible monitor incompatibility
If the R-wave synchronization markers do not appear to be nearly simultaneous with the R­waves on the remote monitor display or are not present, do not proceed with synchronized cardioversion.
The LIFEPAK 20e defibrillator/monitor can be configured to receive an ECG source from a remote monitor (such as a bedside ECG monitoring system) by means of the ECG/Sync connector on the back of the defibrillator/monitor. Refer to "Manual Mode Setup Menu,"
page 8-5. The remote monitor must have a sync out connector and a cable must be provided to
make this connection. Refer to the LIFEPAK 20e Defibrillator/Monitor Service Manual for more details.
Note: The LIFEPAK 20e defibrillator/monitor can be configured to remain in synchronous mode or to return to asynchronous mode after discharge. It is important that you know how your defibrillator is configured. Refer to "Manual Mode Setup Menu," page 8-5.

PEDIATRIC DEFIBRILLATION

Pediatric paddles are part of the standard paddle set (refer to page 5-7).

Pediatric Paddle Placement

Pediatric paddles should be used for patients weighing less than 10 kg (22 lb) or for patients whose chest size cannot accommodate the adult therapy electrodes.
Adult paddles are recommended if the paddles will fit completely on the patient’s chest. Allow at least 2.5 cm (1 in.) of space between the paddles.
For neonates with very small chests, pediatric paddles may be too large to place in the anterior­lateral position. In this situation, place paddles in the anterior-posterior position. Holding the paddles against the chest and back will support the patient on his/her side.
Do not use the pediatric paddles on adults or older children. Delivery of recommended adult energies through this relatively small electrode surface increases the possibility of skin burns.
Anterior-Lateral
The following is the standard pediatric paddle placement (refer to Figure 4-3):
• Sternum paddle to the patient’s right upper torso, lateral to the sternum and below the clavicle.
• Apex paddle lateral to the patient’s left nipple in the midaxillary line, with the center of the
paddle in the midaxillary line if possible.

NONINVASIVE PACING

The LIFEPAK 20e defibrillator/monitor provides noninvasive pacing using QUIK-COMBO electrodes.
The following paragraphs include:
Noninvasive Pacing Warnings
Demand and Nondemand Pacing
Noninvasive Pacing Procedure
Troubleshooting Tips for Noninvasive Pacing
For information about noninvasive pediatric pacing, refer to the Physio-Control Therapy Electrodes Operating Instructions.

Noninvasive Pacing Warnings

WARNINGS!
Possible inducement of ventricular fibrillation.
Sinus bradycardia may be physiologic in severe hypothermia (i.e., appropriate to maintain sufficient oxygen delivery when hypothermia is present), and cardiac pacing is usually not indicated.
Possible interruption of therapy.
Observe the patient continuously while the pacemaker is in use. Patient response to pacing therapy, e.g., capture threshold, may change over time.
Possible inability to pace.
Using other manufacturers’ combination therapy electrodes with this device could cause a decrease in pacing efficacy or the inability to pace because of unacceptably high impedance levels.
Possible patient skin burns.
Prolonged noninvasive pacing may cause patient skin irritation and burns, especially with higher pacing current levels. Discontinue noninvasive pacing if skin becomes burned and another method of pacing is available.

Demand and Nondemand Pacing

The noninvasive pacemaker can be used for either demand (synchronous) or nondemand (asynchronous) pacing modes.
4Therapy
The demand mode is used for most patients. In the demand mode, the LIFEPAK 20e defibrillator/ monitor/pacemaker inhibits pacing when it senses the patient’s own beats (intrinsic QRSs). In demand mode, if the ECG amplitude is too low to detect the patient’s beats, or if an ECG lead becomes detached so that the ECG rhythm is not present, the pacemaker generates pacing pulses asynchronously. This means that the pacemaker generates pacing pulses at the selected rate, regardless of the patient’s ECG rhythm.
Asynchronous or nondemand mode can be selected if noise or artifact interferes with proper sensing of QRS complexes. Press the
OPTIONS button to access the nondemand mode. (Refer
to page 2-7.)
LIFEPAK 20e Defibrillator/Monitor Operating Instructions 4-25
©2006-2013 Physio-Control, Inc.
Therapy
The LIFEPAK 20e defibrillator/monitor has an integrated pulse oximeter that can be used in conjunction with a noninvasive pacemaker to help confirm capture. To confirm capture, compare the pulse rate measured by the oximeter to the set pacing rate of the pacemaker.

Noninvasive Pacing Procedure

ECG monitoring during pacing must be performed with the ECG electrodes and patient ECG cable. Pacing therapy electrodes cannot be used to monitor ECG rhythm and deliver pacing current at the same time. Be sure to place the therapy electrodes in the proper locations as described in the pacing procedure. Improper electrode placement may make a difference in the capture threshold.
To pace, perform the following:
1 Press
ON.
2 Connect the patient ECG cable, apply ECG electrodes to the ECG cable and patient, and
select Lead I, II, or III. To receive the best monitoring signal, ensure there is adequate space between the ECG electrodes and the therapy electrodes.
3 Identify the QUIK-COMBO electrode sites on the patient. For pacing, use either the anterior-
lateral or anterior-posterior position (refer to page 4-3).
4 Prepare patient's skin for electrode application as described in Step 3 of the Defibrillation
Procedure. 5 Apply QUIK-COMBO electrodes to the patient. 6 Connect the therapy electrodes to the therapy cable. 7 Press
PACER. Confirm the LED illuminates, indicating that the power is on.
Note: If the
REMOVE TEST PLUG message appears, disconnect test plug and connect
therapy electrodes to QUIK-COMBO therapy cable.
8 Observe the ECG rhythm. Confirm that a triangle sense marker appears near the middle of
each QRS complex. If the sense markers do not appear or are displayed in the wrong location
(for example, on the T-wave)
, select another lead. (It is normal for the sense marker location
to vary slightly on each QRS complex.) 9 Press
RATE or rotate the Speed Dial to select the desired pacing rate.
Note: The
RATE button changes the rate in 10 pulse per minute (ppm) increments; the
Speed Dial changes the rate in 5 ppm increments.
10 Press
CURRENT or rotate the Speed Dial to increase current until electrical capture occurs.
For each delivered pacing stimulus, the
PACER indicator flashes off and a positive pace
marker displays on the ECG waveform. 11 Palpate the patient's pulse or check blood pressure and compare the SpO
pulse rate with the
2
set pacing rate to assess for mechanical capture. Consider use of sedation or analgesia if
patient is uncomfortable.
Note: The
CURRENT button changes the current in 10 mA increments; the Speed Dial
changes the current in 5 mA increments.
Note: To change rate or current during pacing, press
RATE or CURRENT, and then rotate
the Speed Dial.
Note: To interrupt pacing and view the patient's intrinsic rhythm, press and hold the
PAUSE button. This causes the pacer to pace at 25% of the set rate. Release the PAUSE
button to resume pacing at the set rate.
12 To stop pacing, reduce current to zero or press
Note: To defibrillate and stop noninvasive pacing, press
PACER.
ENERGY SELECT or charge the
defibrillator. Pacing automatically stops. Proceed with defibrillation.
4-26 LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Therapy
If the monitor detects ECG leads off during pacing, pacing continues at a fixed rate until the ECG lead is reattached. During fixed-rate pacing, the pacemaker delivers pulses at the set pace rate regardless of any intrinsic beats that the patient may have. The monitor continues to display the pacing rate (ppm) and the current (mA). To reestablish demand pacing, reattach the ECG lead.
While pacing, visually monitor the patient at all times, do not rely on the
ECG LEADS OFF warning
to detect changes in pacing function. Routinely assess the ECG for proper sensing, pace pulse delivery, electrical capture, and mechanical capture.
If pacing electrodes detach during pacing, the
CONNECT ELECTRODES and PACING STOPPED
messages appear and an alarm sounds. The pacing rate is maintained and the current resets to 0 mA. Reattaching the pacing electrodes silences the alarm and removes the
ELECTRODES
message. The current remains at 0 mA until you increase the current manually.

About Therapy Electrodes

There are two pre-gelled, self-adhesive therapy electrodes available: QUIK-COMBO pacing/ defibrillation/ECG electrodes and FAST-PATCH defibrillation/ECG electrodes (Figure 5-1). QUIK-COMBO electrodes are used for defibrillation, synchronized cardioversion, ECG monitoring, and pacing. FAST-PATCH electrodes can be used for defibrillation, synchronized cardioversion, and ECG monitoring, but not for pacing. To use FAST-PATCH electrodes with the LIFEPAK 20e defibrillator/monitor requires the addition of a FAST-PATCH defibrillation adapter cable.
Figure 5-1 QUIK-COMBO and FAST-PATCH Electrodes
A QUIK-COMBO or FAST-PATCH electrode set:
• Is a substitute for standard paddles.
• Provides a Lead II monitoring signal when placed in the anterior-lateral position.
• Quickly restores the ECG trace on the monitor following defibrillation.
To help prevent electrode damage:
• Do not fold the electrodes.
• Do not trim the electrodes.
• Do not crush, fold, or store the electrodes under heavy objects.
• Store therapy electrodes in a cool, dry location. These electrodes are designed to withstand environmental temperature fluctuations between -40° to 50°C (-40° to 122°F). Continuous exposure to temperatures above 23°C (73°F) reduces the shelf life of electrodes.
There are several types of QUIK-COMBO electrodes available as described in Table 5-1.
