LIFEPAK 15 Monitor/Defibrillator Operating Instructions
Noninvasive Pacing
To perform noninvasive pacing:
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, make sure there is adequate space
between the ECG electrodes and the therapy electrodes.
3. Identify the QUIK-COMBO therapy electrode sites on the patient. Use either the anterior-lateral
or anterior-posterior position and prepare the patient’s skin. (See "Therapy Electrode and
Standard Paddle Placement" on page 5-4.)
4. Apply therapy electrodes to the patient.
5. Connect the therapy electrodes to the therapy cable.
6. Press PACER .
7. 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), adjust ECG SIZE, or select another lead. (The sense marker location
may vary slightly on each QRS complex.)
8. Press RATE or rotate the SPEED DIAL to select the desired pacing rate.
9. Press CURRENT or rotate the SPEED DIAL to increase current until electrical capture occurs.
Electrical capture is indicated by a wide QRS complex and a T-wave following the pace marker.
For each delivered pacing stimulus, a positive pace marker displays on the ECG waveform.
Note: Dashes (---), not heart rate, are displayed on the Home Screen during noninvasive pacing,
and heart rate alarms are disabled.
10.Palpate patient's pulse or check blood pressure to assess for mechanical capture. Consider use
of sedation or analgesia if patient is uncomfortable.
Note: To change rate or current during pacing, press RATE or CURRENT . The RATE and CURRENT
buttons allow changes in increments of 10; the SPEED DIAL allows changes in increments of 5.
Note: To interrupt pacing and view the patient's intrinsic rhythm, press and hold PAUSE . This
causes the pacer to pace at 25% of the set rate. Release PAUSE to resume pacing at the set rate.
WARNING
POSSIBLE INEFFECTIVE PACING
The ECG size must be properly adjusted so that the patient’s own beats are detected.
If ECG size is set too high or too low, pacing pulses may not be delivered when
required. Adjust ECG size so that sense markers are placed on the patient’s QRS
complexes.
