Video analysis of cardiopulmonary resuscitation performance of ambulance crews during transportation

High quality of chest compressions during cardiopulmonary resuscitation (CPR) is a critical determinant of outcome from out-of-hospital cardiac arrest (OHCA). Unfortunately, however, victims often do not receive adequate chest compression for various reasons, particularly during transportation. Recent studies have demonstrated the interruption time of chest compression using transthoracic impedance analysis, but more information is needed to evaluate the performance of CPR provided by ambulance crews and reveal reasons for hands off chest during CPR.
