Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests. It measures lungfunction, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
Spirometry is a simple test used to help diagnose and monitor certain lung conditions by measuring how much air you can breathe out in one forced breath.
Spirometry can be used to help diagnose a lung condition if you have symptoms of a problem, or your doctor feels you’re at an increased risk of developing a particular lung condition. it may be recommended if you have a persistent cough or breathlessness, or if you’re over 35 and smoke.
Spirometry tests are used to diagnose these conditions:
- COPD
- asthma
- restrictive lung disease (such as interstitial pulmonary fibrosis)
- other disorders affecting lung function
They also allow your doctor to monitor chronic lung conditions to check that your current treatment is improving your breathing.
