Abstract
Using a non-invasive blood pressure measuring apparatus that comprises a cuff, a pressurizing unit and bleeding valve, methods to acquire the arterial response to pulsating blood flow through an artery against the bleeding cuff's pressure are described. There are also described method for displaying in real time the entire arterial response on a display unit such as a CRT or LCD, which show the physical and psychological environment where a subject is placed. With the acquired data, accurate systolic and diastolic readings sensitive to environmental change are determined while monitoring in real time the entire arterial response. Remote monitoring of blood pressure can be done by transmitting the acquired data via telephone lines or directly to medical personnel or other instruments.
