The effects of decreased pH and hypoxemia on vascular conductance were investigated and compared in isolated skeletal muscular, coronary and mesenteric artery segments. When blood PO2 was lowered from 100 mm Hg to 30 mm Hg, the conductance rose to 1.76 times control level in the skeletal muscular vessels, to 1.58 times control in the coronary vessels and to 1.47 times control in the mesenteric vessels. The conductance rose in all three vessel types when the pH was gradually lowered from 7.40 to 7.10, rising to 1.87 times control level in the femoral, to 1.67 times control level in the coronary and to 1.29 times control in the mesenteric vessels.
