7. When the defibrillator has reached the selected energy level, press the
located on the handle of the right internal paddle. The defibrillator will not discharge until it
completes charging to the selected energy level. If the
60 seconds, the stored energy is removed automatically.
Note: For safety reasons, the
paddles are connected.
Internal Synchronized Cardioversion Procedure
Refer to the Operating Instructions provided with your LIFEPAK defibrillator for available
mode settings. It is important to know how your defibrillator is configured.
Energy selection is automatically limited to a range of 2—50 joules when internal paddles are
connected.
To use internal paddles for synchronized cardioversion:
1. Connect the internal paddles to the LIFEPAK defibrillator as shown in Internal Defibrillation
Procedure (on page 15).
2. Turn the defibrillator on. Confirm that the internal defibrillation energy of 50 joules or less
appears on the device display screen.
Note: The factory default setting is 10 joules.
3. If desired, select a different energy level.
4. Select

5. Change the ECG size (gain) to the lowest setting, 0.25.
6. Select

7. Hold the paddles as shown in Internal Defibrillation Procedure, and place the conductive
surface of the paddles against the patient's right atrium and left ventricle.
8. Confirm that a stable ECG signal is present and that triangle sense markers appear on the
R-wave (near the middle of each QRS complex).
Note: The patient's ECG acquired through internal paddles may be unreliable for
synchronized cardioversion due to excessive noise or artifact, causing inappropriate R-wave
detection. If the sense markers do not appear or are displayed in the wrong location (for
example, on the T-wave), acquire the patient's ECG through ECG electrodes connected to
the LIFEPAK defibrillator.
9. Charge the defibrillator.
10. Make certain all personnel, including the operator, stand clear of the patient, operating table
or bed, and any equipment connected to the patient.
