After calibration, into detection interface；
C. subject's relevant information is filled in；
D. judge whether previous step is completed, if it is not complete, subject continues to fill in, it is full into measurement blood oxygen if completed
And degree；
Measurement blood oxygen saturation: blood oxygen module is worn on any one clean finger top of subject and carries out detecting sphygmus and blood oxygen saturation
Measurement；
F. judge whether previous step is completed, if it is not complete, whether the position of prompt subject wears' blood oxygen module is correct, or
Whether finger has foreign matter, and tester continues to measure detecting sphygmus and blood oxygen saturation；If completed, measured into lung capacity；
G. before subject starts expiration, software can prompt blowing method and points for attention, and subject exhales according to prompt；
H. judge whether previous step is completed, if it is not complete, prompting subject to carry out again the reason of prompt subject's failure
Expiratory measurements；If completed, measured into exhalation concentrations；
I. when exhalation concentrations measure, the acquisition of exhaled gas is carried out first, before subject starts expiration, software can prompt blowing gas stream
Section is measured, expiratory gas flow is maintained 3 ~ 10s in section according to prompt by subject；
J. judge whether previous step is completed, if it is not complete, prompt subject carries out exhalation test again；If completed, into
Enter the exhaled gas concentration analysis stage；
