A large body of experimental data indicates that blood flows during CPR because of elevations of intrathoracic pressure and the uneven peripheral transmission of this pressure. Data from humans are less extensive, but also strongly support the mechanism of intrathoracic pressure. It should be remembered that the intrathoracic pressure and direct cardiac compression hypotheses are not mutually exclusive, and that effective CPR is above all dependent on vigorous chest compression. ⋯ These data demonstrate that CPR is an effective means of supporting the circulation during cardiac arrest. The majority of survivors return to a meaningful existence, and the technique has not burdened society with a large load of neurologically impaired patients. Thus, CPR is very much worthy of the full attention and support of the medical community.

ReviewAbdominal binding and counterpulsation in cardiopulmonary resuscitation.
During the past 15 years, many different studies have documented improved blood pressure and blood flow above the diaphragm when some type of abdominal compression was added to conventional CPR, either in animals or in humans. Rhythmically interposed abdominal compressions seem to provide even greater hemodynamic benefit than continuous abdominal binding. ⋯ It requires no special equipment, and could be easily incorporated into existing training programs for basic rescuers. In this sense the technique may constitute a logical evolution in basic life support, if subsequent clinical research confirms that it improves outcome.
