Background. Cardiopulmonary resuscitation (CPR) feedback devices are being increasingly used. However, current accelerometer-based devices overestimate chest displacement when CPR is performed on soft surfaces, which may lead to insufficient compression depth. Aim. To assess the performance of a new algorithm for measuring compression depth and rate based on two accelerometers in a simulated re...

Introduction Previous research has shown that increased coronary perfusion pressure (CPP) during cardiopulmonary resuscitation (CPR) correlates with increased coronary blood flow and improved survival from sudden cardiac arrest. The purpose of this clinical study was to determine if a novel chest compression device (AutoPulse, Revivant Corp) improves hemodynamics during CPR when compared with m...

This paper reports on an exploration whether feedback, derived from the comparison of a programmed baseline and actual chest compressions during cardiopulmonary resuscitation (CPR), will help trainees to improve their chest compression movement without the need for personal training by a coach. A prototype is constructed that is used to investigate if it is possible to reliably detect chest com...

Aim The Japanese government has developed a standardized training program for emergency call dispatchers to improve their skills in providing oral guidance on chest compression to bystanders who have witnessed out-of-hospital cardiac arrests (OHCAs). This study evaluated the effects of such a training program for emergency call dispatchers in Japan. Methods The analysis included all consecuti...

Principles of cardiovascular physiology tell us that during cardiac arrest and CPR, forward flow of blood can be generated by external compression or decompression of either the chest or the abdomen. Standard CPR utilizes only one of these modes--chest compression--and generates roughly 1 L/min forward flow in an adult human, which is 20% of normal cardiac output. IAC-CPR uses two of these mode...

Cardiopulmonary resuscitation (CPR) has been thought to produce blood flow by compression of the heart between the sternum and spine, termed "external cardiac massage," but there has been-no direct experimental documentation of this proposed mechanism. Micromanometric pressure recordings were synchronized with cineangiograms during mechanical CPR in 17 dogs with induced ventricular fibrillation...
