1. An intermittent pneumatic compression device for facilitating fluid circulation in a body by alternating between a higher pressure and a lower or no pressure in an associated inflatable cuff, comprising: an inflatable cuff for an extremity; a blower providing air at a pressure less than 130% of the higher pressure at the inflatable cuff, wherein the blower is continuously on during the alternating cycles of pressure; a passageway that remains continuously open during the alternating, said passageway extending between said blower and said inflatable cuff; and a vent valve coupled to said passageway, said vent valve having a rotating paddle that when closed has one side adjacent said passageway and an opposite side adjacent a path to the atmosphere; whereby the vent valve can be opened when a lower or no pressure condition in the inflatable cuff is desired, and can close when the higher pressure is desired.
