Abstract: A device and method are provided the purpose of increasing arterial blood flow to the lower leg, calf, ankle and foot. The device is a compression boot, or cast, and consists of a mono-compartment bladder enclosed in a non-elastic outer envelope connected to an air compressor with regulator valve, providing fast inflation to pressures over 80 mm Hg, within 0.5 seconds. This high pressure compression phase is sustained for 2 seconds. Decompression occurs rapidly, within 0.5 seconds, by venting a large valve to the atmosphere. During the resulting low pressure phase (pressure 0-30 mm Hg), which lasts between 8-14 seconds, there is a marked increase in arterial blood flow.
