Abstract

PURPOSE
The delivery of optimal respiration rate (RR) and tidal volume (TV) is a challenging issue during cardiopulmonary resuscitation (CPR). Amflow is a newly designed feedback device to optimize ventilation. The aim of study is to verify the efficacy of this device for delivering the correct RR and TV during simulated CPR.
METHODS
This prospective, random cross-over designed study included a total of 40 participants who were trained for ventilation method. Using the self-inflating bags with Amflow and without Amflow, participants delivered 5-min of ventilations to test the lungs connected to gas flow analyzers. The correct RR and TV were defined as 10 breaths/min and 500-600 mL, respectively.
RESULTS
For RRs during CPR, the Amflow group showed significantly higher proportions of delivering the correct RR (99.0%, 198/200) than the control group (ventilation without Amflow) (12.0%, 24/200) (p<0001). For TVs, the mean TVs were higher in the control group (535.4±87.9) than in the Amflow group (505.4±39.1) (p<0.001). Proportions of delivering the correct TVs were higher in the Amflow group (56.9%, 1,137/1,999) than in the control group (46.4%, 929/2,003) (p<0.001).
CONCLUSION
Amflow could be useful in delivering the correct RR and TV for ventilations using bag-mask bags during CPR.
