WebMyocardial hypoxia is the result of disproportion between oxygen supply and demand. Owing to the high coronary arteriovenous difference, the myocardium is not able to bring about a substantial improvement in oxygen supply by the increased extraction of oxygen from the blood; thus the only way of meeting the higher oxygen demand is through an … WebActivation of β 2 -adrenoceptors attenuates the increase in pulmonary artery pressure during hypoxic exposure. This compensatory reaction activated by β 2 -adrenoceptors during hypoxic stress is very important to maintain the activities of normal life. Abstract: The acute hypoxic compensatory reaction is accompanied by haemodynamic changes.
