Lung Capacity Test

Simply put, it is the total volume of air exhaled after a maximal inhalation, used to assess pulmonary function and overall physical fitness.

How to Perform the Test

First, take a deep breath—inhale as deeply as possible.
Place your lips tightly around the mouthpiece and exhale steadily and forcefully, without pausing or breaking the flow.
The device will display the measured value; typically, the test is performed 2–3 times, and the highest reading is recorded.
