General Information

Summary of New Features

The following table summarizes the new features that are implemented in this software version 1.5. The version previously released was 1.4.

Feature Reference

Patient alarm tones are now discontinuous, and life-threatening alarms beep at a faster pace than other patient alarms.

If you press to silence a patient alarm tone and a new patient vital sign alarm or equipment alert occurs, a tone for the new alarm or alert will break the silence period at the monitor.

Intended Use

The Micropaq™ monitor is intended to be used by clinicians for single or multiparameter vital signs monitoring of ambulatory and nonambulatory pediatric and adult patients in health care facilities. It is also intended for patient transport. The monitor is able to withstand light rain exposure over short periods of time (uniform distribution of approximately 1 mm of water/ minute for 10 minutes or less).

See “Respond to a Patient Alarm at

Monitor” on page 36.

The Micropaq monitor is intended to operate with an Acuity wireless communication over Welch Allyn’s FlexNet devices to the Acuity Central Station through hardwired Ethernet networks and Wireless Local Area Networks (WLANs). If the Micropaq monitor is moved out of range or loses communication with the FlexNet network, it continues to monitor the patient, display patient data, and generate local patient alarms or alert messages.

• The ECG channel is intended primarily for five-lead ECG monitoring, although three-lead ECG monitoring is supported.

• The Pulse Oximetry channel is intended for continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO (measured by an SpO

sensor).

“Battery Status and Possible

on page 44.)

WARNING Do not try to monitor neonatal patients with the monitor. The monitor is intended for adult or pediatric patients. It is not intended for use with pediatric patients (or infants) weighing less than 22 lbs (10 kg).

4 Chapter 1 General Information Welch Allyn Micropaq Monitor

WARNING Always check the patient mode at Acuity when monitoring a new patient. The patient mode determines default alarm limits and internal algorithm settings.

WARNING The monitor may not meet its performance specifications if stored or used outside the specified temperature and humidity ranges.

WARNING Do not connect more than one patient to a monitor. Do not connect more than one monitor to a patient.

WARNING During defibrillation, keep the discharge paddles away from ECG and other electrodes, as well as other conductive parts in contact with the patient.

WARNING Do not operate this product in the presence of flammable anesthetics or other flammable substances in combination with air, oxygenenriched environments, or nitrous oxide; explosion can result.

WARNING Do not use the monitor in a Magnetic Resonance Imaging (MRI) suite or a hyperbaric chamber. Such use can cause fire or explosion resulting in patient injury and monitor damage.

WARNING Electronic equipment that emits strong electromagnetic or radio frequency signals can cause electrical interference with monitor operation. This interference may distort the ECG signal, thereby preventing accurate rhythm analysis. Avoid operating this device near equipment of this type.

WARNING Exposure to Radio Frequency (RF) radiation. To comply with Federal Communications Commission (FCC) RF exposure requirements, this device shall be used in accordance with the operating conditions and instructions provided in this manual, including the section “Install the Carrying Pouch” on page 28.

WARNING Pacemaker signals can differ from one pacemaker to the next. The Association for Advancement of Medical Instrumentation (AAMI) cautions that “in some devices, rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms. All pacemaker patients should be kept under close or constant observation.” See “ECG Specifications” on page 50 for disclosure of the pacemaker pulse rejection capability of this instrument.

WARNING For patients with a pacemaker, position the monitor to maintain a minimum 6-inch distance between the monitor and pacemaker. Immediately turn the monitor off and provide appropriate patient care if you have any reason to suspect that the monitor is interfering with the pacemaker. The Health Industry Manufacturers Association recommends this minimum 6-inch distance between a hand-held wireless radio and a pacemaker, which is consistent with the independent research by, and recommendations of, Wireless Technology Research.

Directions for Use Chapter 1 General Information 5

WARNING Make frequent electrical and visual checks on cables, sensors, and electrode wires. All cables, sensors, and electrode wires must be inspected and properly maintained and in proper working order to allow the equipment to function properly and protect patient safety.

WARNING Avoid electrosurgery burns at monitoring sites by ensuring proper connection of the electrosurgery return circuit so that the return paths cannot be made through monitoring electrodes and probes.

WARNING Use of ECG cables not specified by Welch Allyn may negate defibrillator protection and risk patient injury due to shock.

WARNING To ensure patient safety, the conductive parts of the ECG electrodes (including associated connectors) and other patient-applied parts should not contact other conductive parts, including earth ground, at any time.

WARNING Motion artifact can affect the accuracy of patient vital sign measurements. Minimize patient motion whenever possible.

WARNING For best product performance and measurement accuracy, use only accessories supplied by Welch Allyn or recommended in the Welch Allyn Products and Accessories booklet (810-0409-XX). Use accessories according to your facility’s standards and the manufacturer’s recommendations. Always refer to the manufacturer’s Directions for Use.

WARNING As with all medical equipment, carefully route the patient cabling to reduce the possibility of patient entanglement or strangulation. Use the supplied garment clips to secure the cable properly.

WARNING When positioning the monitor pouch on the patient, make sure the straps do not entangle the patient’s neck or cause choking. Make sure the straps do not restrict the movement of the patient’s limbs or create a hazard when walking or moving.

WARNING If a product has been dropped or severely abused, send it to a qualified service person to confirm proper operation.

Caution Do not autoclave the monitor. Autoclave accessories only if the manufacturer’s instructions clearly approve it. Many accessories can be severely damaged by autoclaving.

It is possible for the monitor to detect a problem that prevents the monitor from operating properly. If this occurs, the monitor displays an error message and error number. Report such errors to Welch Allyn. The monitor should be serviced only by a Welch Allyn service technician while under warranty. Contact Welch Allyn for information about post-warranty period service.

Understanding the Monitor and the FlexNet Network

The monitor is intended to operate with an Acuity® Central Station as part of Welch Allyn’s FlexNet network. FlexNet allows multiple devices to communicate through hardwired Ethernet networks and Wireless Local Area Networks (WLANs). The Acuity Central Station provides the primary display and entry of patient data for a patient connected to the monitor.

To Other Access Points

FlexNet Network

Each patient-worn monitor supports two-way communication with an Acuity Central Station through an access point in the FlexNet network. The access point is a digital radio transceiver that connects to the FlexNet network. During monitoring, the monitor sends the patient data to Acuity. Acuity and the monitor continuously analyze the data. Acuity provides appropriate alarm or alert messages at the Central Station and other network devices such as a hallway message panel and the monitor itself. Acuity also stores the patient data for viewing or report printing.

If the monitor is moved out of range or loses communication with the FlexNet network and Acuity, it continues to monitor the patient and display patient data. While not communicating with Acuity, the monitor continues to generate local patient alarms or alert messages. Patient data is not stored and Acuity does not perform waveform analysis or generate arrhythmia messages while the monitor is not communicating with Acuity.

When the monitor is returned to within range of the FlexNet network, it automatically reconnects to Acuity.

WARNING The monitor will show + + + for HR numerics between 301 and 350 beats per minute. Above 350 beats per minute, it may display incorrectly low heart rates, due to intermittent picking of R-waves.

WARNING Do not use the monitor in a Magnetic Resonance Imaging (MRI) suite or a hyperbaric chamber. Such use can cause fire or explosion resulting in patient injury and monitor damage.

22 Chapter 2 Monitoring Welch Allyn Micropaq Monitor

WARNING High-intensity radio frequency (RF) energy from external sources, such as an improperly connected electrosurgical unit, can induce heat into electrodes and cables which can cause burns on the patient. Reading errors and damage to equipment may also result. This hazard can be reduced by (1) avoiding the use of small ECG electrodes, (2) selecting ECG electrode attachment points remote from the surgical site and from the electrosurgical return electrode, (3) using electrosurgical return electrodes with the largest practical contact area, and (4) assuring proper application of the electrosurgical return electrode to the patient.

WARNING Verify patient mode at Acuity. Incorrect patient mode may result in inaccurate heart rates and inappropriate alarm settings.

WARNING To help prevent injury, use the provided garment clips to route the ECG cables away from the patient’s head.

WARNING Use of ECG cables with loose or faulty detachable lead wires may cause erratic behavior of the ECG waveform due to intermittent ECG lead wire connections.

Caution To protect the monitor from damage during defibrillation, for accurate ECG information, and for protection against noise and other interference, use only ECG electrodes and cables specified or supplied by Welch Allyn (these cables have the required current-limiting resistors). Follow recommended application procedures.

Caution Do not use an ECG cable longer than 10 feet (3 meters). If the nominal length of the ECG cable, including extensions, exceeds this length, the monitor is not guaranteed to meet published electromagnetic compatibility (EMC) performance specifications.

• Even though the monitor contains fully isolated patient-connected circuitry, it has not been specially designed for direct application on a patient’s heart.

• Use only with accessories provided or recommended in the Welch Allyn Products and Accessories booklet (810-0409-XX).

• Severe artifact and interference (such as defibrillation interference) can cause the waveform to move off the display for a few seconds before it is restored.

Directions for Use Chapter 2 Monitoring 23

Perform 5-Lead ECG Monitoring

1. Inspect the ECG cable and replace it if it shows any signs of wear, breakage, or fraying. Plug the cable into the monitor.

2. Select electrode sites on the patient.

Choose flat areas; avoid fatty or bony areas and major muscles.

3. Shave or clip hair from electrode sites, thoroughly clean skin, and lightly rub dry.

You may use soap and water, isopropyl alcohol or special skin preparation pads. To avoid allergic reactions to electrodes, refer to the electrode manufacturer’s directions.

4. If you are using pre-gelled electrodes, make sure the electrode date is not expired and the gel is intact and not dried out. For best results, use only silver/silver chloride electrodes.

If you are using ungelled electrodes, apply a 1/4- to 1/2-inch mound of gel over the electrode contact area.

For best product performance and measurement accuracy, do not use stainless steel needle electrodes, squeeze bulb electrodes, or electrodes with dissimilar metals. Due to polarization, such electrodes can generate offsets beyond the monitor’s capabilities. Do not use electrodes from more than one manufacturer on the same patient.

5. Attach lead wires to the electrodes before applying them to the patient. Apply the electrodes to the patient in the proper locations.

Flashing circle indicates the lead is not connected.

Left ArmRight Arm

Right Leg

If the monitor detects that some lead wires are not properly connected, the monitor displays a chest diagram and indicates which leads are disconnected.

The locations of the circles displayed on the monitor for each lead are fixed, and are not affected by the exact placement of the electrodes on the patient. For example, the C lead can be placed on the patient in any one of the V1-V6 locations desired, but will only be displayed on the monitor in the location shown above.

to change the lead.

3-Lead ECG Application with the 5-Lead ECG Cable

Note

You can perform 3-lead ECG monitoring in a similar manner as 5-lead ECG monitoring. You may use the 5-lead ECG cable with detachable electrode lead wires, and connect only the lead wires and electrodes for RA, LA, and LL. Refer to the Welch Allyn Product and Accessories booklet (810-0409-XX) for part numbers.

Follow these steps:

1. P e r f o r m Step 1 through Step 4 on page 23 as described for 5-lead ECG monitoring.

2. Before attaching electrodes to the patient, attach only lead wires for RA, LA, and LL to

3. Apply the electrodes for RA, LA, and LL to the patient in the proper locations.

Be aware that there are some inherent limitations with this application, especially when compared to 5-lead ECG monitoring. These limitations include the restriction to only one displayed lead, ECG lead II. Because only one displayed lead is available (ECG lead II), factors such as a poor electrode connection at RA, LA, or LL can significantly affect performance. To overcome these limitations, the 5-lead ECG monitoring is preferred.

The monitor’s 3-lead ECG monitoring is only available for use with Acuity software versions 6.1 or later.

the 5-lead ECG trunk cable and to the electrodes. Make sure that lead wires for C and RL are DETACHED from the 5-lead ECG trunk cable.

The monitor displays the chest diagram with two circles blinking confirming that the C and RL electrodes are not connected.

4. Observe the monitor and visually confirm that within about 30 seconds, the two circles disappear and the monitor displays the ECG waveform, heart rate, and other patient data.

Be aware that if you connect the C or RL lead wires to the 5-lead ECG trunk cable and apply the C or RL electrodes to the patient, the monitor defaults to 5-lead ECG monitoring and does not enable 3-lead ECG monitoring. To enable 3-lead ECG monitoring, you must disconnect the ECG cable from the monitor for a few seconds, and then begin this procedure again.

Directions for Use Chapter 2 Monitoring 25

Be aware that only ECG lead II is available for display with the monitor’s 3-lead ECG monitoring. No other ECG lead selections are available.

WARNING Do not try to perform this 3-lead ECG monitoring with any 5-lead ECG cable that does not have detachable electrode lead wires as described above. Attempting to perform this procedure with a 5-lead ECG cable which has lead wires cut off or hanging loose and not connected to the patient would present a shock hazard to the patient or clinician.

Perform SpO2 Monitoring

WARNING Oxygen saturation measurements using pulse oximetry are highly dependent on proper placement of the sensor and patient conditions. Patient conditions such as shivering and smoke inhalation may result in erroneous oxygen saturation readings. If pulse oximetry measurements are suspect, verify the reading using another clinically accepted measurement method, such as arterial blood gas measurements on a co-oximeter.

WARNING Use only accessories as listed in the Welch Allyn Products and Accessories booklet (810-0409-XX). Use only Masimo accessories and sensors

with the Masimo SpO the Nellcor SpO

WARNING Tissue damage can be caused by incorrect application or use of a sensor (e.g., wrapping the sensor too tightly, applying supplemental tape, failing to periodically inspect the sensor site, leaving a sensor on too long in one place). Refer to the Directions for Use provided with each sensor for specific instructions on application and use, and for description, warnings, cautions, and specifications.

WARNING Sensors exposed to ambient light while not applied to a patient can exhibit semi-normal saturation readings. Be sure the sensor is securely placed on the patient and check its application often to ensure accurate readings.

option.

WARNING Inaccurate measurements may be caused by venous pulsations.

WARNING The pulse oximeter can be used during defibrillation, but the

readings may be inaccurate for a short time.

WARNING The pulse oximeter should NOT be used as an apnea monitor.

WARNING A very sudden and substantial change in pulse rate can result in

erroneous pulse rate readings. Be sure to validate the patient data and patient condition before intervention or change in patient care.

WARNING Interfering Substances: Carboxyhemoglobin may erroneously increase readings; the level of increase is approximately equal to the amount of carboxyhemoglobin present. Methemoglobin may also cause erroneous readings. Dyes, or any substances containing dyes, that change usual arterial pigmentation may cause erroneous readings.

Directions for Use Chapter 2 Monitoring 27

1. Attach the SpO2 sensor to the patient according to the manufacturer’s directions for use, observing all warnings and cautions.

Each SpO

sensor is designed for application to a specific site on the patient within a

certain size range. To obtain optimal performance, use an appropriate sensor and apply it as described in the sensor’s directions for use.

If excessive ambient light is present, cover the sensor site with opaque material to block the light. Failure to do so may result in inaccurate measurements. Light sources that can affect performance include surgical lights (especially those with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight.

If NIBP will be monitored while using SpO than the SpO

measurements, avoid placing the SpO

, place the NIBP cuff on a different limb

sensor on the same limb as an arterial

catheter or intravascular line.

Loss of pulse signal can occur if the sensor is too tight, there is excessive ambient light, an NIBP cuff is inflated on the same limb as the sensor, there is arterial occlusion proximal to the sensor, the patient is in cardiac arrest or shock, or the patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.

2. Inspect the SpO

cable. Replace it if it shows any signs of wear, breakage, or fraying.

Plug the cable into the sensor and the monitor.

3. After the cable is connected, confirm that the monitor displays SpO

data within a

few seconds.

4. If excessive patient movement interferes with measurements, consider the following possible solutions:

• be sure the sensor is secure and properly applied

• use a new sensor with fresh adhesive backing

• select a different type of sensor

• move the sensor to a less active site

The SpO

system is designed to work satisfactorily during normal patient motion.

Alarms & Alerts

About Alarms and Alerts

Alarms provide a warning about a patient condition (such as a vital sign limit violation).

Alerts provide a warning about an equipment condition that needs attention (such as a

low battery or detached ECG lead).

Alarms and alerts may be detected either by the monitor or by the network. While connected to the network, alarms or alerts are displayed at the monitor and at the Acuity Central Station. Alarms have a higher priority than alerts.

Alarm Holdoffs

To help minimize false alarms, the monitor briefly delays or “holds off” triggering alarms for limit violations for HR/PR or SpO detects that the patient’s vital sign has returned to acceptable limits, the monitor cancels the alarm holdoff. The next time a vital sign limit is violated, the monitor starts a new holdoff period.

Maintenance

This section provides information to help operators of the monitor and the battery charger perform routine maintenance activities such as changing or recharging batteries, inspection, and cleaning.

Change the Battery

1. Remove the depleted battery.

2. Insert a fully-charged battery. Use only batteries supplied by Welch Allyn.

WARNING Before installing a battery, carefully inspect the battery case. If there are any signs of damage, cracks, or leaks, discard the battery properly and do not use it.

Note

The Acuity unit can be configured to allow you a short time (typically 30 seconds or more) to change the monitor battery while the monitor is connected to the network without causing an Acuity equipment alert. If the monitor is connected to the network and the battery is removed for longer than the allowable battery changing time, Acuity generates a DROPOUT equipment alert at the Acuity Central Station.

Recharge a Battery

1. On the monitor battery charger, choose an empty battery well where the LED is off.

2. Insert the depleted battery into the battery well.

3. Confirm that the charger displays a flashing green LED by the battery to indicate the battery is detected or is charging.

4. When the green LED is on continuously, the battery is fully charged. Remove the battery.

If the yellow LED is on continuously, the battery may have reached the end of its useful life. Refer to the table below for suggested responses.

Battery Status and Possible Response

Battery is fully charged.

Battery is charging.

Battery is detected and waiting to be charged.

Something is wrong with the battery or the charger. Remove the battery.

• If the LED goes off, it is probably a battery problem. Insert a new battery into the same battery well. If the new battery charges correctly, then the battery has a problem; discard the battery. The battery reorder number is 008-0647-XX. If the same problem occurs with the new battery, the charger may need repair. Contact biomedical engineering.

• If the LED does not go off when you remove the battery, it is probably a charger problem. Unplug the charger power cord, wait at least 5 seconds, then plug in the charger power cord again. Insert a new battery into the same battery well. If the new battery charges correctly, then the battery has a problem; discard the battery. If the same problem occurs with the new battery, the charger may need repair. Contact biomedical engineering.

The charger can accommodate up to eight batteries. The charger charges a maximum of four batteries at a time. After a battery begins recharging (as indicated by the green LED that flashes on one second, off one second), it is typically fully recharged within four hours at room temperature. After a battery is fully charged, the charger continues to maintain the full charge on the battery until the battery is removed. Leaving a fully-charged battery in the charger will not harm the battery.

Remove batteries from the battery charger if the battery charger will be disconnected from ac power for more than a few days. Do not block the cooling vents at the rear of the battery charger.

The monitor battery charger only charges four batteries at a time. A battery is not fully charged until the green LED is on continuously. Do not remove a battery until it is fully charged.

WARNING The monitor battery is Lithium Ion. Do not incinerate, submerge, crush, disassemble, or autoclave. If a battery has been submerged in liquid, discard the battery properly; do not try to recharge or reuse the battery. Do not short the battery terminals. Do not try to connect the battery to any device except the monitor or the monitor battery charger. Do not expose to high temperature (above 60° C or 140° F). Use only the specified monitor battery charger.

Directions for Use Chapter 5 Maintenance 45

Inspect and Clean the Monitor and Accessories

WARNING Be sure to unplug the monitor battery charger power cord from the electrical power outlet before inspecting or cleaning the battery charger. Exposing the battery charger to liquids such as cleaning solutions while connected to electrical power could result in electrical shock or fire.

WARNING Do not autoclave the monitor, battery, battery charger, or accessories. Do not immerse the monitor, battery, or battery charger in liquid when cleaning. Do not immerse accessories in liquid when cleaning unless the accessory manufacturer’s cleaning instructions explicitly instruct you to do so.

Before cleaning, thoroughly inspect the monitor and all accessories for any signs of damage, cracks, or improper mechanical function of keys or connectors. While gently bending and flexing cables, inspect for damage, cracks, cuts, abrasions, extreme wear, exposed wires or bent connectors. Confirm connectors securely engage. Report damage or improper function to your service department. At least every 12 months, be sure to thoroughly inspect the battery charger case and power cord for damage or extreme wear.

To clean the monitor, batteries, or battery charger:

1. Wipe the equipment with a nearly dry cloth moistened with one of the approved cleaning solutions listed in the table on “Approved Cleaning Solutions” on page 46.

Acuity System with Arrhythmia Option

Arrhythmia Analysis Option when Connected to Acuity

ST Analysis ST Analysis can be performed for any or all of seven leads, depending on the operator selection.

Determined by Acuity Arrhythmia Option software (displayed at Acuity Central Station)

The beat-to-beat heart rate (HR) value is calculated as follows:

HR = 60000/actual RR (bpm). Actual RR = time between last detected QRS complex and previously detected QRS complex (ms). Average HR is calculated on the basis of the mean RR interval in the last 6 seconds or 8 RR intervals (whichever is shorter).

The operator can select a measurement offset.

ST segment shifts are recorded in continuous trend data every second. The operator can inspect trend data to see the duration and elevation or depression for each episode for any time period recorded. The operator can also inspect a summary of ST segment shift data within tabular trends.

Heart Rate Heart rate information is available in the trend data which can be viewed on the display or printed.

The operator can inspect the trend data to see the lowest, highest, and median (averaged) heart rates. Trend data also includes the total beats per range of time.

Definition of Pause Arrhythmia Event

A pause is defined as the R-R interval which is greater than or equal to two times the average R-R.
