System for evaluating AMS (acute mountain sickness) risk on basis of IHT (intermittent hypoxia training) dynamic performance

Abstract

The invention provides a system for evaluating AMS (acute mountain sickness) risk on the basis of IHT (intermittent hypoxia training) dynamic performance. The system comprises a data collection module, a data processing module, a robust enhancement module and an AMS severity degree monitor, wherein the data collection module obtains SpO2 (peripheral oxygen saturation) information from a pluralityof continuous IHT periods; the data processing module carries out abnormal value processing, filtering and data segment division on the obtained SpO2 information to select a hypoxia data segment; an index acquisition module obtains DSI (Dynamic SpO2 Index) of the hypoxia data segment, wherein the DSI is duration for keeping the SpO2 to be at a set ratio or above, and is marked as [tao]i; the robust enhancement module carries out robustness enhancement on the DSI [tao]i to obtain an index [tao]r; and the AMS severity degree monitor compares a preset reference value with the [tao]r 4to evaluatethe AMS. By use of a human hypoxia stress response dynamic process reflected by continuous physiological information in the IHT, the invention puts forward the novel system for predicting the DSI by the AMS.

Description

technical field [0001] The invention relates to a system for evaluating AMS risk based on IHT dynamic performance, and belongs to the technical field of prediction and evaluation of acute mountain sickness. Background technique [0002] Acute mountain sickness (AMS) is a special manifestation of insufficient hypoxia tolerance. This common altitude sickness symptom is caused by thin oxygen and low air pressure. People who have no experience of adapting to the plateau environment will have related symptoms when they suddenly enter the plateau, including headache, insomnia, anorexia and so on. Although acute mountain sickness acts as a hypoxic stress response to help the body adapt to the changing environment and establish a new homeostasis, the sustained response seriously affects people's life at high altitudes. [0003] In the field of sports, intermittent hypoxia training (IHT) is a very popular training method, which can improve athletes' sports performance and reduce th...

Problems solved by technology

However, this method of diagnosis is subjective and will be misdiagnosed if the tester denies relevant symptoms

[0006] 3) Static physiological indicators are difficult to predict accurately

However, these static indicators are highly refined and difficult to reflect the dynamic process

[0007] 4) Existing prediction methods are difficult to accurately predict AMS in real time

As the current internationally recognized diagnostic standard for acute mountain sickness, LLS has been widely used, but it is also limited by the long evaluation cycle and subjectivity, making it difficult to diagnose and evaluate accurately in a timely manner

Static physiological indicators but contain highly refined hypoxic stress response information, susceptible to unavoidable perturbations in experiments

Due to differences in experimental design, experimental subject selection criteria, poster height, etc., it is also possible to get the opposite diagnostic conclusion
