Cutaneous vascular conductance (CVC) in response to increasing doses of acetylcholine (ACh) in normotensive (NTN; filled symbols) and hypertensive adults (HTN; open symbols). Maximal CVC (max) was elicited by perfusion of sodium nitroprusside during local heating to 43°C at the conclusion of the ACh dose-response protocol. ACh-induced vasodilation was blunted in HTN adults. *P<0.05 vs. NTN.
