8.6 Change of rhythm
The Saver One analyses the patient's heart rhythm continuously, during the resuscitation phase.
If the device after recommending the shock detects a change in the heart rate of the patient who no longer needs a
defibrillation, it will carry out the automatic disarmament. This phase is highlighted by the following commands:
8.7 Non-shockable rhythm
If the Saver One does not detect a VF or a VT during heart rate analysis, it will inform the operator using the following
commands:
All rhythms other than VF and VT will be considered as non-shockable. For more information, paragraph 10.6.
8.8 CPR
The Saver One defibrillator will guide the operator to CPR (Cardio Pulmonary Resuscitation) in one of the following
cases:
A shockable rhythm was detected and a defibrillation shock was delivered
A non-shockable rhythm was found
A shockable rhythm was found but the patient's rhythm changed
The Saver One will provide instant by instant instructions for performing CPR, instructing the operator on how to
perform chest compressions and insufflations. According to the 2017 AHA/ERC guidelines, the duration of cardio-
pulmonary resuscitation is about 2 minutes.
If resuscitation is carried out by a single operator, the compressions/insufflations ratio must be 30/2 for 2 minutes (5
cycles) for both adult and child patients.
During the phase of chest compressions, the Saver One mediates a metronome which will set the rhythm to maintain in
order to perform the compressions at the right time. Once the compressions have ended, you will need to perform the
two breaths. These instructions are repeated throughout the CPR phase, or about 2 minutes.
