Improve manual ventilation and CPR with ETCO2 Audible Cue
ETCO2 Audible Cue helps the caregiver manage ETCO2 during manual ventilation and CPR by delivering 5 different, easily recognizable sounds to indicate 5 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 Cue.1

Example of situation
Manual ventilation and ROSC confirmation
・Hypoventilation is caused by insufficient manual ventilation during transport
・ROSC is achived*
35 - 44
Ventilation is sufficient
20 - 34
Hyperventilation is caused by over aggressive manual ventilation during transport
CPR (chest compression)
10 - 19
High quality chest compressions are achieved
Quality of effectiveness of chest compression may need improvement
