Name of the Procedure:

Spirometry (Pulmonary Function Test)

Summary

Spirometry is a simple breathing test that measures how much and how quickly you can move air out of your lungs. This test is commonly used to diagnose and monitor lung conditions such as Chronic Obstructive Pulmonary Disease (COPD).

Purpose

Spirometry primarily addresses respiratory issues associated with COPD. The goals are to assess lung function, diagnose the severity of COPD, monitor disease progression, and evaluate the effectiveness of treatment.

Indications

• Patients experiencing chronic cough, breathlessness, wheezing, or recurrent respiratory infections.
• Smokers and former smokers aged 40 and above.
• Patients with a family history of COPD.
• Individuals exposed to respiratory irritants.

Preparation

• Avoid heavy meals before the test.
• Do not smoke or engage in strenuous exercise for at least an hour before the test.
• Inform your doctor about all medications you are currently taking; some may need to be paused before the test.

Procedure Description

1. The patient will be seated and a clip will be placed on their nose to prevent air leakage.
2. The patient will be instructed to take a deep breath and exhale as forcefully and completely as possible into a spirometer.
3. The test may be repeated several times to ensure accuracy.
4. Sometimes, the procedure includes repeating the test after administering a bronchodilator to evaluate its effect on lung function.

Duration

The procedure typically takes around 15 to 30 minutes.

Setting

Spirometry is usually performed in a hospital, outpatient clinic, or specialized pulmonary function lab.

Personnel

The test is typically conducted by a respiratory therapist or technician, and the results are interpreted by a pulmonologist or a primary care physician.

Risks and Complications

• Common: slight dizziness, shortness of breath, or coughing immediately after the test.
• Rare: induced asthma attack or fainting in patients with severe breathing issues.

Benefits

• Accurate diagnosis and assessment of COPD severity.
• Enhanced ability to tailor treatment plans based on lung function.
• Early detection of lung function decline, allowing for timely interventions.

Recovery

No significant recovery time is required. Patients can usually resume their normal activities immediately after the test. If a bronchodilator is used, mild jitteriness or palpitations may occur but will subside shortly.

Alternatives

• Peak Flow Measurement: Less detailed but can be done at home.
• Full Pulmonary Function Testing: More comprehensive but usually requires more equipment and time.

Patient Experience

During the test, patients may experience some discomfort due to the forceful breathing required. However, the test is generally not painful. If discomfort occurs, it is usually brief. Healthcare providers will give instructions and support to ensure the patient's comfort and correct technique.
