Abstract: Using an improved noninvasive blood pressure measuring apparatus, dynamic parameters (like stretching and contracting velocity, acceleration, force, power and energy) of human arterial wall motion against both the lowering and increasing pressure of an occlusive cuff are detected. They can be displayed along with other physiological signals like aortic pressure AP and ECG taken from other instruments through a data receiving unit. Then this apparatus with ECG makes it possible to noninvasively detect some abnormalities between the mechanical and electrical cardiac cycle on heart function. The apparatus also detects systolic (SYS) and diastolic (DIA) pressure while increasing the cuff pressure. The apparatus can also examine a non-local information on blood circulation by simultaneously using a second occlusive cuff.

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.
