Abstract:
Measurements of sublingual blood velocity and blood flow were performed at normal body temperature and after both hot and cold stimulation. Laser speckle measurements of blood velocity were compared with measurements of blood flow obtained with a commercial laser Doppler flowmeter. Sublingual blood velocity increased in all subjects in response to both hot and cold stimulation as compared with that at normal temperature.
