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 clip may be placed on your nose to ensure you only breathe through your mouth.
- 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 at least three times.
- Bronchodilator Testing: In some cases, you may be asked to inhale a medication to see if it improves your results (reversibility testing).
How to prepare
To ensure the most accurate results, please follow these guidelines provided by the HSE:
- Medication: Check with your doctor if you should avoid using certain inhalers for a period before the test.
- Clothing: Wear loose-fitting clothes that do not restrict your chest or stomach.
- Diet: Avoid eating a large meal or smoking for at least a few hours beforehand.
- Cautions: Inform our doctors if you have recently had a heart attack or surgery (eye, chest, or abdominal), as these may affect your eligibility for the test.
