Spontaneous Rhythmic Fluctuations of the Cutanous Blood Flow in Man

open access
Using the reflection photoelectric plethysmograph, rhythmic fluctuations of the blood flow were investigated in the human skin. Frequency and amplitude of the rhythmic fluctuations were not synchronous with those in other skin areas. They increased with increase in ambient temperature as well as local heating of the skin. On the contrary they decreased with decrease in ambient temperature as well as local cooling of the skin. A rise in the local venous pressure caused an increase in frequency. The rhythm was suppressed by a cutaneous nerve block, though the suppression was not persistent. Intravenous injection of a large amount of chlorpromazine caused a marked increase in frequency. Rhythmic fluctuations of the blood flow through the fingers and toes of some patients were also investigated. The results suggest that the myogenic automaticity of the vessels may be mainly involved in the rhythmic fluctuations of the blood flow through the skin, and that it may be under the influence of sympathetic nerve activity, perhaps organized at the spinal level.
