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.
