Abstract
Improved procedures for cardiopulmonary resuscitation of a victim of cardiac arrest are provided. In the resuscitation, the victim's chest is mechanically compressed and decompressed to stimulate the heart. The victim is induced to inspire and expire against insufflating breathing gas during the chest compression/decompressions. The breathing gases are adduced under pressure to promote the development of a positive coronary perfusion pressure.Electro-stimulation of the heart can be carried after positive coronary perfusion pressures have been achieved. The electro-stimulation can be defibrillation or heart pacing or both. The chest compression/decompression cycles and the electro-stimulation measures are synchronized to promote sufficiently body circulation of oxygenated blood in a subject suffering from cardiac arrest. Medical equipment systems are provided for implementing the CPR procedures.
