- PreviewCardiopulmonary resuscitation (CPR) training for laypeople has been markedly stimulated in out-of-hospital cardiac arrest (OHCA). Continuous effective chest compressions is a key element to provide organ perfusion and improve clinical outcomes.1 The effectiveness of chest compressions includes correct hands position on the chest, compression rate between 100 and 120 cpm, compression depth between 5 and 6 cm, and complete chest release after each compression. The optimal hand position due to chest compression was reviewed by the International Liaison Committee on Resuscitation (ILCOR) with recommendation of the middle or center of the chest.
