Abstract : This report describes a microcomputer-controlled system which measures limb blood flow by strain gauge plethysmography. Hardware components include a suitable microcomputer, compatible data acquisition unit, Hokanson EC- 4 plethysmograph, pneumatic cuff inflation system, and a relay/switching unit for remote calibration of the plethysmograph unit and inflation of the pneumatic cuffs. The software developed for use with this system enables automatic electronic calibration of the plethysmograph prior to each measure of limb blood flow, collection and storage of limb volume records at user-specified time intervals, interpretation of limb volume records, and calculation of rates of limb blood flow....
