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.

Alberta Teachers Association Conference


background 550

On November 12th our Western Canada Territory Manager, Stacey Metz traveled to beautiful Banff Alberta and experienced the breath taking Rocky Mountains. This wasn’t a ski trip however, Stacey was representing AYVA as we exhibited at the Alberta Teachers Association annual Science Conference.

Teachers ranging from elementary to post-secondary were excited to connect with each other at this three day conference. The days were packed with outstanding workshops and fantastic speakers. Teachers appreciated the range of workshop topics with lots of ideas to engage their students.

Keynote speaker and Olympic Gold Medalist, Adam Kreek was inspirational as he detailed his experience and the adventures he encountered while gathering scientific data from our oceans. He and his team continue to educate youth about the importance of conserving our ocean’s resources.
