Spirometry Procedure: What to Expect

 

A spirometry procedure is a form of pulmonary function test that checks the proper functioning of the lungs. In this procedure, the expert measures how much air goes into and leaves the lungs while breathing. It also oversees the pace at which one can exhale air from the lungs.

 

Reasons for Spirometry Test

 

Healthcare professionals generally perform a spirometry test for the following reasons:

 

  • Diagnose conditions like asthma, COPD, and other respiratory disorders.
  • Monitor disease progression and response to treatment.
  • Evaluate symptoms such as chronic cough, wheezing, or shortness of breath.
  • Assess lung function before surgeries, especially thoracic or abdominal procedures.

Determine the impact of occupational exposures on lung health.

 

Preparations for Spirometry Test

 

To ensure accurate results with this test, you can prepare yourself in the following ways:

 

  • Avoid having heavy meals right before the procedure.
  • If you are on any medication, consult your doctor about the prescription beforehand.
  • Avoid smoking for at least 24 hours before the test.
  • Experts recommend not engaging in an intensive physical workout 30 minutes before the procedure.
  • Wear loose, comfortable clothing that does not restrict breathing.

 

Process of Spirometry Test

 

The spirometry test involves the following steps:

 

  • Positioning:You will be seated upright, and a clip will be placed on your nose to ensure all breathing is through the mouth.
  • Breathing Manoeuvre: You will take a deep breath in, then exhale as forcefully and completely as possible into a mouthpiece connected to the spirometer.
  • Repetition: This process is typically repeated at least three times to ensure consistency and accuracy.
  • Bronchodilator Test (if applicable): In some cases, you will inhale a bronchodilator medication, wait 15 minutes, and then repeat the test to assess the medication's effect on your lung function.

The entire procedure usually takes between 15 to 30 minutes.

 

Interpretation of Spirometry Test Results

 

Spirometry results are compared to standard reference values based on age, sex, height, and ethnicity. Key interpretations include:

 

  • Normal: FEV₁ and FVC values are within the expected range.
  • Obstructive Pattern:Reduced FEV₁/FVC ratio, indicating conditions like asthma or COPD.
  • Restrictive Pattern:Reduced FVC with a normal or increased FEV₁/FVC ratio, suggesting conditions like pulmonary fibrosis.

Your healthcare provider will discuss the results and any necessary next steps.

 

Risks Involved in Spirometry Test

 

While spirometry is safe for most people, it may not be recommended if you have:

 

  • Recent heart attack or unstable heart conditions
  • Uncontrolled high blood pressure
  • Recent eye, chest, or abdominal surgery
  • Active respiratory infections

These conditions can increase the risk of complications during the test, so a medical evaluation is essential beforehand.

 

The spirometry procedure is a common test that medical experts advise their patients to undergo when they visit with issues relating to breathing. It also gives reliable outcomes on the basis of which experts make foolproof treatment plans for subjective patients. Make sure to always consult your healthcare provider to determine if spirometry is appropriate for you.
