LIFEPAK 15 Monitor/Defibrillator Operating Instructions

Noninvasive Pacing

To perform noninvasive pacing:

1. Press

2. Connect the patient ECG cable, apply ECG electrodes to the ECG cable and patient, and select

Lead

, 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

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.
