Abstract
A method and system are provided for detecting various vascular conditions using an occlusive arm cuff plethysmograph. The system includes data acquisition hardware, including the occlusive arm cuff plethysmograph, for obtaining arterial and endothelial function data from a patient, processing means utilizing application or analysis software for analyzing the arterial and endothelial function data, and a database of computer models, such as brachial artery pressure versus lumen area curves (P-A curves) and brachial artery pressure versus compliance curves (P-C curves), developed by analyzing data for a plurality of subjects where their vascular conditions were known. The processing means diagnoses and predicts various vascular conditions pertaining to the patient by comparing or correlating the analyzed arterial and endothelial function data with the computer models stored within the database and presents the findings on a display.
