The effect of chest compression with voice on cardiopulmonary resuscitation

Abstract

Results : The depth, rate of chest compression, and ventilation volume were not affected by a voice (p >.05), and the ratio of chest compression to ventilation kept 30:2, when the subject made a sound (p <.05).Conclusion : Making voice during CPR was associated with an accurate ratio of 30:2 and the reduction in hands off time.
