Important Patient and Safety Information

The cardiograph isolates all connections to the patient from electrical ground and all other conductive circuits in the cardiograph. This reduces the possibility of hazardous currents passing from the cardiograph through the patient’s heart to grou nd.
WARNING Failure to follow these warnings could affect both patient and operator safety.

Accessories and Supplies

WARNING Always clean and disinfect reusable electrodes before patient use. Failure to properly
clean and disinfect reusable electrodes before patient use may cause infectious materials to be transferred between patients.
WARNING The Welsh bulb electrodes (available as an accessory for the cardiograph) do not meet
the requirements of IEC 60601-2-25 for defibrillation recovery time, and cannot be reliably used for patient diagnosis immediately following defibrillation.
WARNING When using additional peripheral equipment powered from an electrical source other
than the cardiograph, the combination is considered to be a medical system. It is the responsibility of the operator to comply with IEC 60601-1-1 and test the medical system according to the requirements. For additional information contact Philips Medical Systems.
WARNING Do not use non-medical peripherals within 6 feet of a patient unless the non-medical
peripherals receive power from the cardiograph or from an isolation transformer that meets medical safety standards.
CAUTION The Welsh bulb electrodes contain natural rubber latex which may cause allergic reactions.
CAUTION The use of equipment that applies high frequency voltages to the patient (including electrosurgical
equipment and some respiration transducers) is not supported and may produce undesired results.
xii PageWriter TC20 Cardiograph Instructions for Use
CAUTION Only use Philips Medical Systems replacement parts and supplies with the cardiograph. The use of non-
approved replacement parts and supplies with the cardiograph is strictly prohibited. Cardiograph safety and performance are not guaranteed when non-approved replacement parts and supplies are used with the cardiograph.
Using accessories, peripherals, or cables that are not supplied with the cardiograph or that
are not recommended by Philips Medical Systems can result in increased emissions or decreased immunity of the cardiograph.
Connect other equipment in accordance with IEC 60601-1-1 Medical Electrical Systems
Standard or IEC 60601-1: 2005 (3rd Edition) Medical Electrical Equipment Standard Clause 16 Medical Electrical Systems.
When connecting the cardiograph to other AC powered equipment, only connect
equipment approved to IEC 60601-1 Medical Electrical Equipment or IEC 60950-1 Information Technology Equipment.
Only use patient electrodes that are approved by Philips Medical Systems. The use of non-
approved patient electrodes may degrade cardiograph perfo rmance.
T o prevent burns to the patient , remove all ECG electrodes and and the patient cable prior
to the use of high frequency surgical equipment (including electrosurgical equipment and some respiration transducers).

1The Patient Session

Introduction

A patient session is the period of time when waveform data is acquired and processed from a single patient. A patient session begins by entering accurate patient information. Patient information is then linked with all waveform data acquired during the patient session.
CAUTION Entering accurate patient information (age, gender) is highly recommended if using the Philips 12-
Lead Algorithm, version PH090A, or the Philips DXL ECG Algorithm, version PH100B, for ECG interpretation. For more information see the applicable Physician’s Guide on the PageWriter TC Cardiograph User Documentation DVD, or download the file from the Philips InCenter site incenter.medical.philips.com.
Before acquiring an ECG, ensure that the cardiograph screen does not show the DEMO MODE
watermark on the waveform screen or report, and the Patient ID does not display the text, Simulated data. If these elements are present, the cardiograph is in Simulation mode and is not acquiring patient data! Restart the cardiograph to exit Simulation mode. For details, see “Working with Simulated Data” on page 1-25.

Patient Preparation
Thorough patient preparation techniques are essential for a good quality ECG. Follow the procedures listed in this section to ensure a quality ECG for each patient.
TIP Good ECG technique is very important to achieve the best quality results.

Instructing the Patient

Before attaching the electrodes, greet the patient and explain the procedure. Explaining the procedure decreases anxiety and informs the patient about what to expect.
Privacy is important to relaxation. When possible, take the ECG in a quiet room or area
where others can’t see the patient. Draw the curtains around the bed when taking the ECG in a room with other people.
Reassure the patient that the procedure is painless. Make sure the patient is lying down and is comfortable. The patient’s arms and hands must
be relaxed. If the table is too narrow, place the patient’s hands under the buttocks to prevent muscle tension in the arms.
3-4 PageWriter TC20 Cardiograph Instructions for Use

Preparing the Skin

Once the electrodes and patient cable are attached, instruct the patient to:
Remain still and do not talk Breathe normally Try not to shiver Do not chew or clench teeth
The more relaxed the patient, the less the ECG will be affected by noise.
Preparing the Skin
Thorough skin preparation is very important. The skin is a poor conductor of electricity and frequently creates artifact that distorts the ECG signal. There is a natural resistance on the skin surface due to dry, dead epidermal cells, oils, and dirt.
TIP The area of the skin where the electrodes are applied must be clean and free of skin oil.
To prepare the skin:
1
Clip hair from electrode sites if necessary (excessive hair prevents a good connection).
2 Wash thoroughly with soap and water. 3 Dry the skin vigorously to increase capillary blood flow to the tissues and to remove the
dead, dry skin cells and oil.
TIP Do not use alcohol to clean the skin because it dries the skin. If there is no time to follow the
procedure above, rub the site with gauze to remove dead, dry skin and to increase capillary flow.

Attaching Disposable Electrodes

Attaching Disposable Electrodes
For the best quality ECG, ensure that all skin preparation procedures described in “Preparing the Skin” on page 3-5 have been followed.
To attach disposable electrodes:
1
Expose the arms and legs of the patient (to place the limb electrodes).
2 Place the electrodes on flat, fleshy parts of the arms and legs. 3 Place the electrodes on the inside of each arm (between the wrists and elbows). 4 Place the electrodes on the inside of each calf (between the knee and the ankle). 5 Place the limb electrodes equal distance from the heart. Position the electrodes at the same
place on each limb.
6 If a limb site is not available (amputation, injury) place the electrodes closer to the torso. 7 Attach the electrodes to the skin. A good test for firm electrode contact is to try to move it.
If it moves easily, the electrode connection is too loose. Do not allow the electrodes to move in any way.

Attaching Welsh Bulb and Limb Clamp Electrodes

Special Note about Welsh Bulb Electrodes
Special care is necessary when using Welsh Bulb electrodes. Pay special attention to all warning associated with these electrodes. For information on cleaning the reusable Welsh Bulb electrodes, see “Reusable Electrode Cleaning” on page 5-5. Philips recommends the use of disposable electrodes at all times with the PageWriter TC cardiograph.
WARNING The Welsh bulb electrodes (available as an accessory for the cardiograph) do not meet
the requirements of IEC 60601-2-25 for defibrillation recovery time, and cannot be reliably used for patient diagnosis immediately following defibrillation.
WARNING Always clean and disinfect reusable electrodes before patient use. See “Reusable
Electrode Cleaning” on page 5-5 for information on cleaning and disinfecting reusable electrodes. Failure to properly clean and disinfect reusable electrodes before patient use may cause infectious materials to be transferred between patients.
CAUTION The Welsh bulb electrodes contain natural rubber latex which may cause allergic reactions.
PageWriter TC20 Cardiograph Instructions for Use 3-9
Patient Preparation
The Welsh Bulb electrode is a self-restraining electrode that consists of a rubber squeeze bulb and a metal cup. The rubber squeeze bulb provides sufficient suction to hold the electrode firmly on the patient without causing discomfort. This electrode is used on the chest. The limb clamp electrodes are used on the arms and legs. Philips recommends the application of highly conductive multipurpose electrolyte gel to the electrode site whenever Welsh Bulb and limb clamp electrodes are used.
Figure 3-3 Welsh Bulb and Limb Clamp Electrode
For the best quality ECG, ensure that all skin preparation procedures described in “Preparing the Skin” on page 3-5 have been followed.
To attach limb clamp and welsh bulb electrodes:
1
Expose the arms and legs of the patient (to place the limb plate electrodes).
2 Inspect both the limb clamp and the Welsh Bulb electrodes to ensure that both are clean.
For information on cleaning reusable electrodes, see “Reusable Electrode Cleaning” on page 5-5.
3 Ensure that the patient cable and the lead wires are not twisted, and lay the patient cable
flat.
4 Connect the lead wire to the corresponding electrode, this may be done one electrode at a
time for convenience.
5 Apply a thin layer of electrolyte gel to the area of the skin where the electrode will be
applied. The skin area covered by the electrolyte gel should not exceed the diameter of the electrode.
3-10 PageWriter TC20 Cardiograph Instructions for Use

Attaching the Patient Cable

6 Rub the electrode on the skin with a circular motion to apply and spread the electrolyte gel
to the electrode surface and skin. This is very important if the patient’s skin is extremely dry . If the patient’ s skin is excessively hairy, follow the procedure “Preparing the Skin” on page 3-5 to remove hair from electrode sites.
CAUTION When applying the precordial electrodes, do not overlap the electrolyte gel of adjacent electrode
sites. Overlapping electrolyte gel will cause interaction between electrode sites, and may result in distortion of the ECG signal.
7 Hold the electrode on the patient’s skin and depress the top of the rubber bulb. 8 Release the rubber bulb, and the electrode attaches to the patient. A good test for firm
electrode contact is to try to move it. If it moves easily, the electrode connection is too loose. Do not allow the electrodes to move in any way.
TIPS Place the electrodes on flat, fleshy parts of the arms and legs.
Place the electrodes on the inside of each arm (between the wrists and elbows).
Place the electrodes on the inside of each calf (between the knee and the ankle).
Place the limb electrodes equal distance from the heart. Position the electrodes at the same
place on each limb.
If a limb site is not available (amputation, injury) place the electrodes closer to the torso.
To remove limb clamp and welsh bulb electrodes:
Detach the rubber bulb from the metal cup by pulling. Follow the procedure, “Reusable
Electrode Cleaning” on page 5-5, to clean reusable electrodes after each use.
Attaching the Patient Cable
Each lead wire tip is labeled and color-coded for easy identification.
To attach the patient cable:
Attach each lead wire to the corresponding electrode.

Troubleshooting Signal Quality

Always follow good skin and patient preparation techniques prior to taking an ECG. Proper skin preparation helps to ensure a good quality ECG. Skin is a poor conductor of electricity and frequently creates artifact that distorts the ECG signal. For more information, see “Patient Preparation” on page 3-4.
A dotted line, known as a “leads off” trace will appear on the display when there is a poor connection between the electrode and the patient.
Use the following table to identify and correct the connection:

Special Note about Artifact Filter

A
BC
DECF
Special Note about Artifact Filter
The purpose of the Artifact filter is to remove skeletal muscle artifact from the ECG signal. Skeletal muscle artifact is the most difficult noise source to eliminate due to the fact that it contains the same frequencies as actual patient ECG signals. The Artifact filter will eliminate skeletal muscle artifact, but it will also reduce all high frequency components of the ECG signal. Due to this fact, use of the Artifact filter may make it impossible to detect pacemaker pulses, and may affect P waves, and the entire QRS-T complex. Only use the Artifact filter for ECGs that otherwise would be unreadable due to significant levels of muscle artifact.
