New Methodology of Human Health Express Diagnostics Based on Pulse Wave Measurements and Occlusion Test

Abstract

Nowadays, with the increase in the rhythm of life, the relevance of using express diagnostics methods for human health state estimation has significantly increased. We present a new express diagnostics method based on non-invasive measurements (the pulse wave shape, heart rate, blood pressure, and oxygen saturation of blood vessels and tissues). A feature of these measurements is that they can be carried out both in the hospital and at home. The new compact and portable optical hardware–software complex has been developed to measure tissue oxygen saturation. This complex makes it possible to reduce the measurement time from 60 min to 7–8 min, which reduces the likelihood of artifacts in the measurement process and increases its reliability. A new technique has been developed to carry out these measurements. A new optical sensor based on a line of charge-coupled devices has been developed to register a pulse wave in the far peripheral zone. The developed new technique for processing the pulse waveform and data on the oxygen saturation of hemoglobin in the blood and tissues allows a person to obtain additional information about their state of health independently. It will help to make conclusions about taking the necessary measures. This additional information allows the attending physician to provide more effective control over the course of treatment of the patient at any time since the methods of express diagnostics proposed by us have no restrictions on the number of applications. The functional state of more than 300 patients was studied. The results of various measurements are presented.

Recent Progress of Wearable Triboelectric Nanogenerator-Based Sensor for Pulse Wave Monitoring

“…Physicians frequently employ cuff-based blood pressure monitors, which can only measure blood pressure intermittently [ 12 ]. Electrocardiography (ECG) [ 13 ] and Photo Plethysmo Graphy (PPG) [ 14 ] are the two primary methods used by the majority of heart rate sensors [ 15 ]. Although PPG is a noninvasive test that uses photoelectricity to detect changing blood volume in living tissue, it can yield incorrect measurements due to factors such as variations in the color of the skin, the distance from the artery, and interference from ambient light [ 16 , 17 ].…”
