Mild External Compression of the Leg Increases Skin and Muscle Microvascular Blood Flow and Muscle Oxygenation during Simulated Venous Hypertension
Anterior tibialis muscle microvascular blood flow measured by photoplethysmography (PPG) and muscle oxygenation measured by near-infrared spectroscopy (NIRS). External leg compression of 40 mmHg during simulated venous hypertension using a 65 mmHg thigh tourniquet significantly increases muscle microvascular blood flow and muscle oxygenation. In addition, muscle oxygenation levels during compression are similar to those values during recovery measures. * repeated measures ANOVA comparing 6 min data point to data points at 7–12 min. ‡ repeated measures ANOVA comparing 6 min data point to data points at 7–12 min.
