Forced expiration total amount prediction method

Abstract

The invention discloses a forced expiration total amount prediction method, which comprises the following steps: S1, according to a forced lung function prediction standard, collecting forced lung function test data, and sorting and classifying the data to obtain a data set; and S2, constructing a forced expiration total amount prediction model, and outputting a forced expiration total amount prediction result by using the prediction model. The method has the beneficial effects that by providing the forced expiration total amount prediction method, a tester can still obtain an FVC value under the condition that the whole test is not completed, so that the problem that the diagnosis effect is influenced due to the fact that an FVC detection result does not meet the acceptability because it is difficult for the tester to insist in expiration time long enough is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment and physiological signal detection, in particular to a method for predicting the total amount of forced expiratory breath. Background technique [0002] Chronic obstructive pulmonary disease (COPD) is a common lung disease. According to statistics, COPD is the fourth leading cause of death worldwide. Studies have shown that early diagnosis and treatment of COPD is an important means to reduce mortality. Forced vital capacity test has become an important way to evaluate and diagnose COPD. The key indicators include forced expiratory volume (FVC), forced vital capacity in the first second (FEV1 ) and one-second rate (FEV1 / FVC). If FEV1 / FVC is small, usually FEV1 / FVC<0.7, but FVC is normal, it is judged as obstructive ventilatory dysfunction. It can be seen that FVC is one of the key indicators for evaluating pulmonary ventilation function. [0003] In order to obtain accurate FVC, A...

Problems solved by technology

In fact, due to some objective reasons, it is difficult for the tester to persist in exhaling for a long enough time, which leads to the unacceptability of the FVC test results, thus affecting the diagnosis

Therefore, it is necessary to solve the probl
