WebObjective: We tested the hypothesis that peripheral vasodilation has an effect on arterial oxygen saturation measurements by pulse oximetry, independent of temperature. Methods: Study 1 compared finger arterial oxygen saturation values (SpO(2)), before and after peripheral vasoconstriction while temperature was kept constant. This was achieved by … WebVasopressor response Being blocked by 5-HT 2 receptor antagonists (ketanserin, cyproheptadine, and pizotifen), this response is due to activation of vascular 5-HT2 receptors (resulting in peripheral vasoconstriction) in several species including rats, cats, dogs, monkeys, and humans [1,2,8,9,39].
