Improve manual ventilation and CPR with ETCO₂ Audible Cue

ETCO₂ audible Cue helps the caregiver to manage ETCO₂ during manual ventilation and CPR by delivering five different, easily recognizable sounds to indicate five ranges from high to low ETCO₂. Audible Cue provides the caregiver with instant feedback about ETCO₂ level changes without needing to look at the monitor.

The following figure shows the results of a study comparing manual ventilation with no capnometric monitoring and with capnometric monitoring with and without Audible Cue¹.

Primarily designed for	ETCO2 range* [mmHg]	Audible Cue sound type <click to enlarge>	Audible Cue sound design <click to enlarge>	Example of situation
Manual ventilation and ROSC confirmation	45≤ (High)			Hypoventilation is caused by insufficient manualventilation during transport ROSC is achieved*
	35 - 44 (Normal)			Ventilation is sufficient
	20 - 34 (Low 1)			Hyperventilation is caused by over aggressive manual ventilation during transport
CPR (chest compression)	10 - 19 (Low 2)			High quality chest compressions are achieved
	≤9 (Low 3)			Quality of effectiveness of chest compression may need improvement
