Mild External Compression of the Leg Increases Skin and Muscle Microvascular Blood Flow and Muscle Oxygenation during Simulated Venous Hypertension

Figure 1

Schematic of the experimental conditions: external leg compression of 40 mmHg; venous hypertension (65 mmHg thigh cuff); external leg compression during venous hypertension. Anterior tibial skin and muscle microvascular blood flows were measured continuously using photoplethysmography (PPG), and muscle oxygenation was measured using near-infrared spectroscopy (NIRS) in the right leg of healthy subjects. Both PPG and NIRS probes were placed over the anterior compartment approximately 5 cm from each other.
