Abstract:
The influences of lactic/hydrochloric acidosis on pulmonary vasoconstriction and gas exchanges were investigated in 36 dogs. The tv infusion of lactic or hydrochloric acid reducing arterial pH to 7. 00 could elicit significant changes of pulmonary hemodynamics, including the consistent increase of pulmonary arterial pressure and the decrease of arterial oxygen saturation. It is suggested that pulmonary vasocostriction is related to arterial PH but not to arterial lactic acid levels.
