(Pulmonary function)

Measure lung function by breathing directly into the device.
· As you get older, your lung function gradually decreases. However, since the loss of lung function occurs little by little, it is difficult to know , so periodic lung function measurements let you know whether or not lung function is lost, and regular management can prevent lung function loss before it deterioated.
· In particular, since lung function can be measured simply and easily , the results can be obtained immediately. Thanks to these advantages, it is possible to measure lung function decline more effectively and respond early.
· Inspection items: Total lung capacity (TLC), Effort expiratory volume for 1 second (FEV1), etc
