What is Audible Cue?

Improve manual ventilation and CPR with ETCO2 Audible Cueaudiblecue_logo_l_1.png

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.

delivering 5 different easily recognizable sounds

The following figure shows the the results of a study comparing manual ventilation with no capnometric monitoring and with capnometric monitoring with and without Audible Cue.1
