What is a spirometry? 

A spirometry is a test which measures the function of the respiratory system.  It can help characterize breathing problems into two main categories – “restrictive” and “obstructive”.  By defining the breathing abnormality, a spirometry aids in diagnosing underlying respiratory diseases, such as asthma or COPD.

How do I prepare for a spirometry?

    1. Fasting is not necessary, however you should avoid taking the test after a heavy meal.
    2. Inhalers generally are not recommended for 48 hours before taking the first spirometry.  If there is already a established diagnosis and the spirometry serves to evaluate the efficacy of treatment, then bronchodilators should be used. You should contact our office to receive instructions specific to your test.
    3. If the spirometry that has been ordered includes a “bronchodilator challenge”, then inhalers should definitely not be used 48 hours before the test.
    4. On the day of the spirometry, you should avoid stimulants, such as caffeine, coffee, and tea.  Medications that can have a depressant effect, such as sleeping pills and anti-anxiety medications, should also be avoided before the test.
    5. Comfortable, nonrestrictive clothing is recommended.
