Spirometry
Spirometry is a safe, non-invasive, breathing test used to assess how well your lungs are working. It provides multiple indices relating to lung function based on tthe amount of air you can inhale and exhale, as well as how quickly you can expel it.
Why is it performed
Spirometry is essential for diagnosing and monitoring several respiratory conditions, including:
- Asthma: Identifying airway narrowing or inflammation.
- COPD: Monitoring Chronic Obstructive Pulmonary Disease, including chronic bronchitis and emphysema.
- Pulmonary Fibrosis: Assessing restrictive lung patterns.
- Cystic Fibrosis: Tracking lung function over time.
- Pre-operative Assessments: Checking if you have sufficient lung function before a scheduled surgery.
- Post-COVID Recovery: Evaluating lingering respiratory issues after a viral infection.
- Occupation Health: Monitoring of lung function for people working in certain settings.
What to expect
The procedure is straightforward and usually takes 15 to 30 minutes:
- Preparation: You will sit upright, and a soft nose clip may be placed on your nose.
- The Manoeuver: You will take a deep breath in, then blow as hard and as fast as possible into a mouthpiece connected to a spirometer.
- Repetition: To ensure accuracy, the test is typically repeated three times.
- Bronchodilator Testing: In some cases, you may be asked to inhale a medication to see if it improves your results (reversibility testing).
