1. A compression garment control unit for monitoring compliance of a user with respect to wearing a compression garment in accordance with a compression treatment regimen, the control unit comprising:
a display configured to display patient compliance with a compression treatment regimen;
an alarm;
a pressure sensor;
at least one computer readable storage medium configured for storing one or more monitored parameters;
one or more processors coupled with the at least one computer readable storage medium; and
computer-executable instructions embodied on the at least one computer readable storage medium, the computer-executable instructions including instructions for causing the one or more processors to:
direct a flow of fluid from a pressurized fluid flow source to cyclically inflate and deflate at least one inflatable bladder of a compression garment configured to be wrapped around a limb of a wearer of the garment;
receive pressure signals indicative of fluid pressure in the at least one inflatable bladder from the pressure sensor communicatively coupled thereto during at least one of inflation and deflation of the at least one inflatable bladder in a plurality of successive compression cycle, with each compression cycle comprising pressurizing the inflatable bladder to a compression pressure and subsequently pressurizing the inflatable bladder to a refill pressure, with the compression pressure being greater than the refill pressure;
process the received pressure signals to determine a venous refill time (VRT); and
initiate the alarm in response to the received pressure signals indicating an interruption of operation or non-compliance with compression therapy when the VRT is lower than a predetermined threshold.
