[Experimentally induced alterations in wedge pressure and O2-partial pressure during acute hypoxia].

Suprarenal occlusion of the aorta by means of a balloon catheter results in an increase in wedge pressure, alterations in blood flow in the pulmonary circulation, and an increase in O2 partial pressure in the arterial blood. It is demonstrated that these changes take place after occlusion of the aorta during normoxia or hypoxia (Pao2:43 mmHg) in anaesthetized normotensive or spontaneously hypertensive mongrel dogs.
