ABSTRACT:
An apparatus and a method are provided for vascular examination of a limb by inflation of a flexible-walled pneumatic chamber mounted to the limb and calibration of the pressure within the chamber in units of volume. Calibration is accomplished by inflating the chamber to a preselected reference pressure, altering the volume of the chamber, and measuring the calibration pressure at the altered volume. The calibration pressure is stored for use off-line in scaling subsequent pressure fluctuations as changes in limb volume.
