5.2.3 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 12a).
The CPR mode for intubated patients consists of continuous 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 12b).
The ventilation in CPR mode is flow controlled ventilation. The tidal volume
is user selectable. The O
2
% 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.
