The effect of the different methods indicating 100/min to 120/min using the metronome in dispatcher-assisted resuscitation

摘要

To enhance the quality of bystander cardiopulmonary resuscitation (CPR), The 2010 American Heart Association guidelines for CPR recommend that emergency medical system dispatchers instruct untrained bystanders in compression-only CPR, with an emphasis on "push hard and fast" [ 1 ]. Because emergency medical system dispatcher-assisted CPR (D-CPR) is conducted by telephone, real-time feedback is impossible and the quality of chest compression, especially the depth of compression, cannot be monitored. However, many studies have found that audio guidance during bystander CPR well maintains the rate of chest compression [2-4]. Metronome guidance is a cost-effective and feasible feedback method that could be applicable in D-CPR.
