Influence of Oxygen on Hypothermic Cardiac Standstill in the Heart-Lung Preparation
Administration of pure oxygen to denervated dog heart-lung preparation subjected to hypothermia does not affect the temperature that induces terminal ventricular fibrillation even when the progressive alkalemia that occurs is prevented. It is concluded that hypoxia of the myocardium is not a factor in the terminal cardiac arrest that supervenes in hypothermia of the heart-lung preparation.
