5.2.4 CPR mode
The CPR mode consists of timed chest compression audible prompts
coupled with automatically delivered breaths for both intubated and mask
ventilated patients. There is also a visual animated display to guide the
health care provider while performing CPR.
The CPR mode for masked ventilated patients is the default setting for
this mode but changes can be made between the 2 sub-modes at any
time.
The CPR mode for masked ventilated patients consists of 2 phases, chest
compression and ventilation. 30 chest compressions over 18 seconds are
synchronized with audible prompts and on screen visual animations,
followed by two, 1 second, mandatory breaths within a 5 second
ventilation phase. The ratio between chest compressions and ventilations
is 30:2 (Figure 13a).

mode
compressions indicated by an audible prompt and visual animation at a
rate of 100 compressions per minute plus automatically delivered breath
every 6 seconds (Figure 13b).
The ventilation in CPR mode is flow controlled ventilation. The default
tidal volume is set according to the initial start-up patient size selection
when switching to CPR mode but could be adjusted to desired values. The
FiO
is fixed at 100% oxygen during CRP mode.

The ventilator will automatically compensate up to 30% of the required
tidal volume Vt in case a leak is detected. Beyond this limit, low Paw visual
and audible alarms will be activated to warn rescuer to either re-apply the
mask or increase the set tidal volume.
