Spirometry (Asthma)

4) Spirometry- How tests are done

Spirometry is a breathing test which can be done at your GP surgery or at a hospital outpatient clinic.

  • Your height and weight are accurately measured.
  • You sit upright with feet on floor on a chair with arms.
  • You will be asked to take a full deep breath in and then BLAST!!! out as hard and as fast as possible for as long as possible.
  • You then breathe in as fully and deeply as possible.
  • The test is repeated three times with a rest in between each test.
