| Abstract: | Background Hands-Only cardiopulmonary resuscitation (CPR) is recommended for use on adult victims of witnessed out-of-hospital (OOH)
sudden cardiac arrest or in instances where rescuers cannot perform ventilations while maintaining minimally interrupted quality
compressions. Promotion of Hands-Only CPR should improve the incidence of bystander CPR and, subsequently, survival from OOH
cardiac arrest; but, little is known about a rescuer's ability to deliver continuous chest compressions of adequate rate and
depth for periods typical of emergency services response time. This study evaluated chest compression rate and depth as subjects
performed Hands-Only CPR for 10 minutes. For comparison purposes, each also performed chest compressions with ventilations
(30:2) CPR. It also evaluated fatigue and changes in body biomechanics associated with each type of CPR. |
