Embodiment Construction
[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0032] A kind of pulmonary function test method based on exhalation mathematical model of the present invention comprises the following steps:
[0033] (1) read the expiratory curve of the subject's forced vital capacity test;
[0034] (2) using the data processing module of the spirometer to be tested to perform data processing on the forced expiratory curve in step (1), to obtain the evaluation index value of lung function;
[0035] The expiratory curve described in step (1) in the present embodiment is figure 1 The dotted line shown in , which meets the forced exhalation time of more than 3 seconds, and also meets the following criteria recommended by the American Thoracic Society / European Medica...
