Summary A microprocessor‐based system of photoplethysmography and its use in measuring skin blood flow is described. The system was designed specifically for use over long periods and for the analysis of the output to be handled by a personal computer. The photoplethysmograph described in this paper is shown to be a qualitative method for assessment of changes in peripheral skin blood flow. There is potential for use of this instrument in a variety of clinical conditions.
