Abstract
A compression apparatus is provided that includes a sleeve configured for disposal about a limb. The sleeve includes a first portion defining a first expandable chamber and a second portion defining a second expandable chamber and a third expandable chamber. The second portion includes a connector in fluid communication with a pressurized fluid source and the chambers thereby facilitating fluid communication between the pressurized fluid source and the chambers. The first portion is removable from the second portion. The first portion may be connected to the second portion via a perforated attachment. The sleeve may define at least one ventilation opening. The connector can communicate with the chambers via a tubular pathway. The sleeve may be convertible from a length extending from below a knee to above the knee, to a length extending solely below the knee.
