Abstract

Skin blood flow affects NIRS. Leg skin blood flow (SkBF) was increased and decreased following local heating and intradermal epinephrine injection. Epinephrine decreased muscle saturation (StO₂), and heating the leg increased StO₂. The results suggest that changes in SkBF can significantly affect resting StO₂ as measured by near-infrared tissue spectroscopy.
