Abstract
Based on the assumption that externally induced pressure variations inside the chest cavity generate life saving blood flow during cardiopulmonary resuscitation (CPR) in cardiac arrest, mathematical models of increased complexities were developed to describe the flow phenomena in the cardiovascular system. The lumped parameter representation of the cardiovascular system describes the flow phenomena during CPR, and is used to optimize the present CPR technique as well as to suggest a new CPR procedure. Clinical experimental studies (dogs) confirm the prediction that a sequential phased abdomino-thoracic compression (PCCPR) yields blood flows which are twice the values obtained in the classical CPR mode of manual chest compression. The newly suggested PCCPR technique greatly improves vital organs' blood flow in CPR and opens a new direction in the field of emergency medicine.
