Manual chest compressions for cardiac arrest - With or without mechanical CPR?

摘要

Chest compressions are fundamental to cardiopulmonary resuscitation (CPR). They provide a circulation during cardiac arrest, and high-quality chest compressions with minimal interruption increase the chance of a successful return of spontaneous circulation (ROSC) and survival.Does it therefore matter whether a circulation during CPR is provided by a device (mechanical CPR) or by human efforts (manual CPR)? A recent Cochrane review stated that there was insufficient evidence to conclude that mechanical CPR was associated with benefit or harm.5 The results of two recent large randomized studies, the LUCAS in Cardiac Arrest (LINC) study and, in this issue, the Circulation Improving Resuscitation Care (CIRC) trial, are therefore timely.The LINC and CIRC studies showed no clear survival to discharge benefit from the use of the LUCAS or AutoPulse (Load distributing band [LDB]) devices respectively.
