the doctor is using a

Spirometer

Explanation:

Jake is undergoing spirometry and the equipment the doctor is using on him is called a spirometer.

Spirometry is an examination of the respiratory system, non-invasive and painless, lasting about half an hour, performed to assess whether there is any abnormality in pulmonary ventilation, screening and quantifying the presence of restrictive and obstructive lung diseases.

During the examination, the patient remains seated in a comfortable chair and must blow through a tube containing a disposable spirometry mouthpiece, connected to the spirometer.

A nose clip is used to prevent the passage of air through the nostrils, ensuring that all breathing is done through the mouth and has to pass through the spirometer that makes the measurements.

During the spirometry examination, the patient will alternatively be asked to breathe calmly for some time, to fill the lung completely and then blow as hard and quickly as possible for at least 6 seconds without stopping to completely empty the lungs and measure the released air. .
