Problems solved by technology

[0004] Although the current non-invasive hemodynamic detection system and color computerized sonography method have high detection accuracy, the cost is high and the required equipment is complicated.
The method based on ECG and pulse wave morphological parameters also needs to attach electrodes, which is difficult to integrate into wearable devices and cannot be continuously measured
Previous multiwavelength photoplethysmography methods only performed theoretical derivation and blood pressure prediction, and did not directly track changes in peripheral vascular resistance

Embodiment 1

[0107] Cold stimulation causes constriction of blood vessels in the fingers, including arterioles. Therefore, cold stimulation can increase the peripheral vascular resistance of fingers. Vasodilation resulted in a decrease in peripheral vascular resistance when the finger was placed at room temperature after a cold stimulus. Based on this principle, we designed a cold stimulation experiment to reduce the temperature of the subject's finger and monitor the arteriolar pulse wave transit time during the recovery process. see Figure 7 , is the transit time of the arteriolar pulse wave after the cold stimulation of the two subjects.

[0108] The sympathetic nervous system is an important part of the autonomic nervous system. Sympathetic nerve excitation can cause many changes in the body at the same time, such as sweat gland secretion, arteriolar constriction, and peripheral vascular resistance increase. Sweat gland secretion leads to changes in skin impedance, which can be de...

Abstract

The invention provides a peripheral vascular resistance change tracking method and system, a terminal and a storage medium, which can be integrated into wearable equipment, the change of peripheral vascular resistance is tracked by accurately acquiring arteriole pulse wave transmission time, and the change of peripheral vascular resistance can be continuously tracked on the body surface in real time.

Description

technical field [0001] The present application relates to the field of electronic information technology, and in particular to a method, system, terminal and storage medium for tracking changes in peripheral vascular resistance. Background technique [0002] At present, the detection method of peripheral vascular resistance is mainly by measuring the cardiac output (cardiac output, CO) to calculate the peripheral vascular resistance. Some researchers use a non-invasive hemodynamic detection system, affix multiple electrodes on the body of the subject, send and receive alternating current signals to depict the cardiac impedance map, calculate the cardiac output (CO) and then calculate the peripheral vascular resistance [1 ]([1] Yang Shuang. Study on the Correlation Between Cardiac Function, Peripheral Vascular Resistance and Serum Hcy and Blood Lipid Levels in Elderly Hypertensive Patients [D]. Shanxi Medical University, 2020.); Some researchers also used color computerized i...
