The Spirometer measures air flow whilst the user breathes. The air flow data can be converted to volume using a simple function in the SMARTSENSE software.

The Spirometer comes with 1 nose clip and 4 flow head filters – one ‘fixed’ and three for test subjects. A flow head contains an antibacterial and antiviral filter to lessen the possibility of cross contamination between subjects. The flow head is for a test subjects use only and should be regarded as a ‘disposable’ item. A circular guard is provided to prevent the ‘fixed’ flow head being used.

Teaching Applications:

  • Breathing patterns before, during and after exercise
  • Lung capacities
  • Lung efficiencies FVC, FEV1 and FEV6, MVV
  • 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
