Abstract: An automated vascular testing apparatus includes capillary blood flow sensors and blood pressure detection sensors to detect data regarding the blood flow of a patient. Error detection apparatus insures that the blood data sensors are properly connected and that the output signals therefrom are reliable and provide an adequate basis for measurement. A controller monitors the output signals from the sensors and manages the overall operation of the automated testing procedures. The controller memory temporarily stores the output signals from the blood data sensors, along with other miscellaneous data. A video display presents instructions, data, and conclusions based on accepted medical theories to the operator, while a printer optionally reproduces these data in hard copy form.
