1. An automated method of applying compression to the body of a subject comprising at least one fitting cycle and at least one treatment cycle, wherein the fitting cycle comprises:
in one or more cycles delivering or removing an amount of a fluid to a chamber of a compression sleeve sufficient to adjust the chamber to a pre-calculated internal pressure less than a treatment pressure target comprising a predetermined percentage of the treatment pressure target and a fitting adjustment factor, and measuring an actual internal pressure of the sleeve after the delivery or removal of the amount of the fluid to the chamber of the compression sleeve, wherein the predetermined percentage of the treatment pressure target is less than 100%;
determining a pressure difference comprising a difference between the actual internal pressure of the sleeve, the pre-calculated internal pressure and the fitting adjustment factor to generate a treatment cycle adjustment factor;
wherein the treatment cycle comprises:
in one or more cycles following the fitting cycle, delivering or removing the amount of the fluid to the chamber of the compression sleeve sufficient to adjust the chamber to the calculated internal pressure comprising the predetermined percentage of a treatment pressure target and the treatment cycle adjustment factor, wherein the predetermined percentage of the treatment pressure target is not less than that of the last fitting cycle.
