Rhythm Detection System - Primedic HeartSave PAD Operating Instructions Manual

Rhythm detection system

13 Rhythm detection system
The rhythm detection system of the PRIMEDIC
ECG and supports you if the device identifies a shockable or a non-shockable rhythm.
The device's rhythm detection system includes:
Ascertaining the electrode contact
Automatic evaluation of the ECG
Operator control of the defibrillation shock therapy
The transthoracic impedance of the patient is measured by the defibrillation electrodes.
If the baseline impedance is greater that the maximum critical value, then the device
ascertains whether the electrodes are not in good enough contact with the patient or if
they are not connected properly to the device. ECG analysis and dispensation of
defibrillation shocks are therefore prevented. The voice output says "Check electrodes"
if the contact of the electrodes is insufficient.
Automatic Interpretation of the ECG
The device's rhythm detection system has been designed so that a defibrillation shock
is recommended if the system has been connected up to a patient who is unconscious,
not breathing and has no pulse and the system ascertains a shockable rhythm.
With all other ECG rhythms, including asystolia and normal sinus rhythms, the rhythm
detection system in the device does not recommend defibrillation.
Operator control of the output of defibrillation shocks
The device's rhythm detection system triggers automatic charging of power if the
device ascertains a shockable cardiac rhythm. Optical and acoustic messages are
emitted to show you that the device recommends giving a defibrillation shock. If a
defibrillation shock is recommended, you decide whether and when the shock is to be
given.
