11.  Protection against electric shock.

 

 

Before defibrillating the doctor releasing the shock has to ask all persons attending to the 
resuscitation clearly and unmistakably to step back from the treatment location and to touch 
neither the patient nor the bed nor the connected devices. Remove any devices without 
defibrillation protection from the patient before releasing the shock. Otherwise energy may flash 
over to persons in unfavourable situations.  

 
12.  Discharge energy (shock). 

 

Prepare the defibrillator for the shock by pressing the release buttons on the paddles 
simultaneously. Keep the buttons pressed down. The shock is released by the ECG as soon as 
the next R-peak is recognized. In case of quick pulse the shock may follow shortly after pressing 
the release buttons simultaneously. A slow pulse may cause an evident delay in time. In this 
case do not reduce the pressure of the paddles on the patient's chest. Keep the release buttons 
pressed down and check the ECG. If no shock follows after several seconds, release the release 
buttons before taking the paddles off the chest.  

 

 

 With 

the 

PRIMEDIC

™

 

Defi-Monitor

 an internal safety discharge is carried out when keeping 

the release buttons pressed down for more than three seconds and no shock is released during 
this time (no R-peak available / detected). After the internal safety discharge the 

PRIMEDIC

™

 

Defi-Monitor

 is available for the next defibrillation in asynchronous mode. 

 

13.  Check the result. 

 

Check the patient's heart rhythm, breathing and condition after the synchronous cardioversion. 
Check the ECG and decide whether a further trial is necessary. If yes, repeat steps 4 to 13. 

 

 

 

Please consider that nearly all defibrillators on the market (

PRIMEDIC

™

 

Defi-Monitor

 

included) switch back to asynchronous mode automatically after a synchronous shock has been 
released. 

 

 

 

Control the heart rhythm over a certain time after successful cardioversion. 

 
14.  Keep the defibrillator ready for use. 

 

Clean the paddles, cable and electrodes at the end of the resuscitation to ensure availability of 
the defibrillator for the next application. Insert the defibrillator into the charging unit to charge 
the accumulator in order to ensure that sufficient energy is available for the next use. 

 
 

In case of malfunctions or faults have the defibrillator checked immediately and if necessary 
repaired by an authorized service technician.
