Therapeutic hypertension system based on a microbreathing pressure sensor system

چکیده
BACKGROUND AND METHODS A novel therapeutic system for the treatment of hypertension was developed on the basis of a slow-breath training mechanism, using a microbreathing pressure sensor device for the detection of human respiratory signals attached to the abdomen. The system utilizes a single-chip AT89C51 microcomputer as a core processor, programmed by Microsoft Visual C++6.0 to communicate with a PC via a full-speed PDIUSBD12 interface chip. The programming is based on a slow-breath guided algorithm in which the respiratory signal serves as a physiological feedback parameter. Inhalation and exhalation by the subject is guided by music signals. RESULTS AND CONCLUSION Our study indicates that this microbreathing sensor system may assist in slow-breath training and may help to decrease blood pressure.

Resistant hypertension, case based approach to diagnosis and management: case report
Background: Resistant hypertension is defined when the blood pressure remains elevated above the therapeutic target levels despite the use of three antihypertensive agents including calcium channel blocker (CCB), renin-angiotensin system (RAS) blocker and a diuretic. These drugs should be used at maximally tolerated doses and white coat effect and non-adherence should also be excluded. In this ...
