Desflurane results in higher cerebral blood flow than sevoflurane or isoflurane at hypocapnia in pigs. [PDF]

, 2004
Background: In clinical neuroanaesthesia, the increase in cerebral blood flow (CBF) and intracranial pressure caused by the cerebral vasodilative effects of an inhalational anaesthetic agent is counteracted by the cerebral vasoconstriction induced by ...

Exercise‐induced potentiation of the acute hypoxic ventilatory response: Neural mechanisms and implications for cerebral blood flow

Experimental Physiology
A given dose of hypoxia causes a greater increase in pulmonary ventilation during physical exercise than during rest, representing an exercise‐induced potentiation of the acute hypoxic ventilatory response (HVR). This phenomenon occurs independently from

Hypocapnia reduces the T wave of the electrocardiogram in normal human subjects

, 2005
During voluntary hyperventilation in unanesthetized humans, hypocapnia causes coronary vasoconstriction and decreased oxygen (O(2)) supply and availability to the heart. This can induce local epicardial coronary artery spasm in susceptible patients.

Blood buffers: The viewpoint of a biochemist

Physiological Reports
Mammalian blood is a very complex system whose multiple physiological roles require that its pH is maintained constant, in spite of the necessity of carrying over 15 moles of CO2 a day from the tissues to the lungs. The blood pH is maintained constant by
