Abstract
Determining whether a compression garment is worn by a wearer of the garment by analyzing a pressure signal waveform indicative of a fluid pressure in an inflatable and deflatable bladder of the compression garment. Variance detected in the pressure signal waveform during the analysis is indicative of a change in condition of the compression garment. In one aspect the change in condition is verified using confirmatory analysis. In another aspect, the variance is one of a pressure rise and a pressure impulse. In yet another aspect, the variance is an oscillating amplitude as a function of time representative of a pulse of the wearer.
