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. Since this apparatus is capable of acquiring any physiological signal coupled with a commonly practiced noninvasive brachial artery blood pressure measurement, it will be also useful for quick and mass clinical testing.
