Breathe Some Life into Physiology with Spirometer Experiments

 

Breathe some life into Physiology- Spirometer (PS_2152)575x100

The Spirometer Sensor is a great way to get students interested in respiration and lung volume— and it can be used to perform several pulmonary function tests (PFTs). The sensor uses a disposable mouthpiece and differential pressure sensor to accurately report the flow rate (L/s), total flow (L), and max flow rate (L/s) for both inhalation and exhalation. Depending on the test being performed, students can set up a graph to display a volume-time curve or flow-volume loop. Two of the most common tests are the forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) which can be used to calculate their FVC/FEV1 ratio. This ratio is often used to test for respiratory disorders such as asthma. To find out how to collect and analyze data for the FVC and FEV1 tests watch these quick tutorials by clicking on the links below.

Please remember that this equipment should not be used for medical diagnosis.
