Abstract

The postocclusive hyperaemic response of cutaneous microcirculation at a site on the volar surface of the forearm was evaluated using the Laser Doppler Perfusion Imager. Nine healthy subjects were studied under three types of externally applied loading conditions. The half-life of hyperaemic response was found to be within 100 seconds post-occlusion after static loading but was about doubled after dynamic loading. The hyperaemic flow did not decay following a single exponential decay pattern, but can be better represented with two exponential decay time constants. The observed adversity effect of dynamic loading to tissue prompts a reevaluation of the strategy in pressure sore prevention.
