What is Audible Cue?

Improve manual ventilation and CPR with ETCO2 Audible Cue

audiblecue_logo_l_1.png
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.

delivering 5 different easily recognizable sounds

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.

Example of situation  
Manual ventilation and ROSC confirmation 45≤
(High)
High.png High_A.png
  • Hypoventilation is caused by insufficient manualventilation during transport
  • ROSC is achieved*
35 - 44
(Normal)
Normal.png Normal_A.png
  • Ventilation is sufficient
20 - 34
(Low 1)
Low1.png Low1_A.png
  • Hyperventilation is caused by over aggressive manual ventilation during transport
CPR (chest compression) 10 - 19
(Low 2)
Low2.png Low2_A.png
  • High quality chest compressions are achieved
