Abstract

The integrated peripheral vascular diagnostic system electronically links a pulse volume recorder PVR, an ocular pneumoplethysmograph OPG, a photoplethysmograph PPG, an audio-frequency analyzer AA unit which characterizes blood flow with a sensitive microphone, and a doppler ultrasound unit. This diagnostic equipment generates data signals. These data signals are converted into digital data signals and are stored in a database. The diagnostic system includes a computer with a processor, a memory, a keypad input device, a display monitor, a printer and an interface for connecting these electronic components together along with an interface for the PVR, OPG, PPG, AA and doppler ultrasound. The diagnostic system further includes a report generator which generates, displays and prints a plurality of vascular diagnostic reports from the digital instrument data signals and the keypad entry data. The diagnostic system also includes, in a further embodiment, an audio playback device such that the technician, when preparing the vascular diagnostic report, can listen to analog versions of the digital instrument data signals. The method for electronically integrating the vascular diagnostic system includes electronically obtaining and converting the instrument data signals into digital data signals, inputting keypad entry data representing manually acquired vascular medical data from the patient, compiling the digital data and the keypad entry data into a database and generating, displaying and printing a plurality of vascular diagnostic reports.
