1157 - Wireless Spirometer Sensor

The Smart Wireless Spirometer best data notes:

To get the best data from any practical

• Make sure the sensor is held vertically during data collection
• Use the calibrate before any data collection to give a zero value for zero airflow (minimise any potential data drift)
• Start data collection during an exhalation

The Smart Wireless Spirometer can be used to investigate a number of scientific experiments such as:

• Measurement of tidal volume
• Breathing patterns before, during, and after exercise
• Lung capacities
• Lung efficiencies FVC, FEV1 and FEV6, MVV (also known as Forced Vital Capacity)
• Flow volume curves
• Slow Vital capacity (SVC): The user should breathe normally 3 times and then inhale to the maximum extent of total lung capacity and then expire to the maximum extent
• Maximal voluntary ventilation (MVV): The user should breathe as deeply and as rapidly as possible over a period of 6 to 12 seconds 

Note: Care should be exercised when performing this test as there is a danger of hyperventilation. Ensure the test subject is sitting down.

Care and maintenance.

• After use wipe the inner surface of the spirometer with anti-bacterial wipes.
• Remove the flow head used by the user and discard, they are single use.
• Store with the “fixed” flow head and guard in position.
• Make sure the spirometer is dried out from use – if necessary leave out to dry overnight – any residual moisture has the potential to allow unwelcome microorganisms to grow.
• After several uses (lessons, not individual) consider replacing the fixed head.

The flow heads are 90%+ effective in trapping bacteria and fungal spores, and will offer high resistance to transfer of viral particles in moisture droplets.

The moisture trapped in the filter of a user’s flow head makes it unacceptable to save the filters for use “another day”.
