From: Quality of cardiopulmonary resuscitation in out-of-hospital cardiac arrest before and after introduction of a mechanical chest compression device, LUCAS-2; a prospective, observational study

  1. No-flow time (NFT) = Time without ROSC – time without chest compressions. ROSC = Return of spontaneous circulation. AED = Automated external defibrillator.
