computer via COM port or USB-to-Serial adapter. Ergometer must be selected prior to starting the test

Subject Preparation

Select the correct mask size for the subject
Selecting the appropriate mask size is crucial for accurate data and subject comfort. A mask which is too large can introduce leaks and a mask which
is too small may make the subject feel claustrophobic limiting performance on the exercise test.
The seal inside the mask should fit from the top of the nose of the subject (between the eyes) to just below the bottom lip with the base of the mask
going underneath the chin.
