Effects of hyperbaric hyperoxia on forearm blood flow (FBF) (A) and forearm vascular conductance (FVC) (B) at rest and during exercise. Hyperoxia did not change resting FBF or FVC compared with normoxia. However, FBF and FVC during hyperoxic exercise were substantially reduced compared with normoxic exercise. FBF and FVC were lower with tyramine infusion at rest, during exercise (normoxia and hyperoxia), and during NTP infusion (normoxia only). *P < 0.01 vs. normoxia. †Main effect of tyramine, P < 0.01.
