FRED easy
Shock advised
The device has detected a shockable rhythm.
Before each shock delivery, the device warns the user not to touch the patient.
If the analysis algorithm detects a shockable rhythm, the device will automatically
charge the required defibrillation energy. Once the energy is charged, the user is
prompted to deliver the shock by pressing the orange button
(only in semi-auto-
matic mode).
In automatic mode, the device alerts the user that the shock will be delivered, and
then delivers the shock without user intervention.
Then the
FRED easy®
informs the user via spoken and written message that the
shock has been delivered.
Shockable conditions include:
– ventricular fibrillation or
– ventricular tachycardia with a rate higher than 150 bpm.
• Each shock is
followed by CPR
The
FRED easy®
informs the user that the patient can be touched again and prompts
the user to perform a cardiopulmonary resuscitation cycle.
According to the configuration of the device, a CPR cycle consists of:
– performing chest compressions during the set period of time, or
– performing alternatively 30 chest compressions and 2 breathes during the set
period of time.
Before each CPR cycle, the device informs the user that the patient can be touched.
The device indicates the position of the hands and the rhythm of chest compressions
with beeps ("metronome"), if applicable.
If the device detects a shockable rhythm, the shock must only be released if the patient
does not show any signs of circulation.
If the device detects that the patient’s heart rhythm has changed to an non shockable
rhythm, the previously recommended shock is immediately cancelled and the energy
is discharged internally.
FRED easy®
informs the user that the shock has been can-
celled.
• For children, the number of chest compressions can be configured to 15 or 30 us-
ing
FREDCO®
. The device recognises the connected electrodes (adult or child
electrodes) and selects the number of chest compressions accordingly.
• CPR duration can be configured in
FREDCO®
and is the same for adults and
children: it can be set between 30 seconds and 7.5 minutes, in steps of 30 sec-
onds.
