Randomized Controlled Trial Comparative Study
A Cluster-Randomized Control Study Comparing a New Cue "Two Compressions per Second" with "100-120 Compressions per Minute" in Training of Bystander Cardiopulmonary Resuscitation.
Chest compression at a rate of 100-120 compressions per minute (cpm) during cardiopulmonary resuscitation (CPR) is associated with the highest survival rates. Performing compressions at a faster rate may exhaust the rescuers. ⋯ The new cue of 'two compressions per second' resulted in participants having a lower compression rate, although it still exceeded 120 cpm.
