Liver adenosine triphosphate (ATP) in hypoxia and hemorrhagic shock

Reduction of liver ATP in proportion to the severity of shock and hypoxia is well known. We have studied the interrelationships among arterial oxygenation, arterial pH, and liver ATP in experimental hypoxia and in hemorrhagic shock in rats. No significant correlation was found between liver ATP and arterial pH in both hemorrhagic shock and hypoxia and between liver ATP and arterial PO2 in hypoxia. Induction of experimental observations suggest that in this form of hemorrhagic shock, arterial pH may be a sensitive indicator of decreased hepatic perfusion and impaired liver ATP production.
