Geddes et al [1] published a preliminary animal study introducing a new method of cardiopulmonary resuscitation (CPR) in which rescuers use only abdominal compressions (OAC) to resuscitate sudden ventricular fibrillation cardiac arrest, which they referred to as OAC-CPR. They reported that the idea of using abdominal compressions during CPR originated with Ralston et al [2] who studied the use of interposed abdominal compressions (IAC) with standard chest-compressions CPR (or IAC-CPR). They suggested that it was logical to explore the potential of using abdominal compressions without chest compressions because blood flow during IAC-CPR was found to be double that of standard chest-compressions CPR, therefore prompting them to conduct their study.
