复合参数生物反馈仪及其在高血压治疗中的初步应用

A Compound-parameter Biofeedback Instrument and Its Application to the Therapy of Hypertension

本文报告一种新的用于原发性高血压治疗的复合参数生物反馈仪。该仪器由单片微机控制，从人体检测出面ΔＺｐｐ、ＨＲ、ＥＭＧ三种生理参数，经放大处理后，三种参数的变化趋势合成为一个复合参数，以视觉和听觉形式反馈给患者，使患者在高度放松的基础上自我调节使心血管系统的外周阻力降低，心输出量减少，血压水平下降。初步临床试用表明，应用复合参数生物反馈仪对原发性高血压患者进行治疗，有明显降低血压的作用。

This paper introduces a new kind of compound-parameter biofeedback instrument which can be used to treat essential hypertension, Based on a single-chip-computer. the instrument detects three physiological parameters (ΔZpp, HR and EMG ) from a hypertensive patient and produces a compound-parameter which indicates the trends of ΔZpp,HR and EMG. By means of visual and audio signals, the compound-parameter is fed back to the patient to reduce his (her) peripheral resistance and cardiac output by self regalatcon. This instrument has been clinically applied to a group of patients with essential hypertension, and the result showed that most of the patients could improve their blood pressure significantly by the compound-parameter biofeedback method.
