ABSTRACT
AIM:
To explore the pathogenic mechanism of high altitude pulmonary edema(HAPE).METHODS:
Haemodynamic changes and effects of 100 percent oxygen breathing were measured by Swan-Ganz thermistor catheters, high altitude healthy volunteers were served as controls.RESULTS:
The important features of haemodynamic changes in HAPE (1)Pulmonary arterial pressure was raised; (2)Pulmonary arterial resistance and cardiac output were raised; (3)Pulmonary artery wedge pressures and right atrial pressure were normal; (4)Pulmonary arterial pressure and resistance were induced by oxygen breathing.CONCLUSIONS:
The normal pulmonary artery wedge pressures with a high cardiac output indicated that HAPE was recognized as a form of noncardiogenic pulmonary edema. The pulmonary hypertension may play an important role in the development of HAPE.
