Spirometry

Spirometry is a vital diagnostic tool used to assess lung function by measuring the volume and flow of air that can be inhaled and exhaled. During the test, you will breathe into a device called a spirometer, which records various parameters, including the Forced Expiratory Volume in one second (FEV1) and the Forced Vital Capacity (FVC).

This information is essential for the diagnosis and management of respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other pulmonary disorders.

Accurate spirometric measurements allow healthcare providers to evaluate the extent of lung impairment, monitor disease progression, and tailor treatment plans effectively.

Regular spirometry testing is crucial for individuals at risk of lung disease, ensuring timely intervention and improved patient outcomes.

The Spirometry Procedure

  • ✺STEP 1

    Your physiologist will take a detailed medical history, which will include your current symptoms, any previous health issues, and the medications you are currently taking.This ensures that a complete understanding of your health status is obtained.

  • ✺STEP 2

    You will need to answer some questions to confirm you are fit for testing. This questionnaire will be emailed to you with your booking confirmation and again on the day of testing to check for any changes.

  • ✺STEP 3

    Your physiologist will then take several measurements, including your height, weight, body mass index (BMI), oxygen saturation levels, heart rate, and blood pressure. These assessments are essential for gaining a comprehensive understanding of your overall health and lung function.

  • ✺STEP 4

    The physiologist will then thoroughly explain the various tests that will be conducted and demonstrate the correct technique to ensure the accuracy and reliability of the results.

  • ✺STEP 5

    The first test will be a Slow Vital Capacity (SVC) test, which measures how much air you can slowly exhale after a deep breath.

    You will perform a minimum of three efforts and testing will be complete when three technically acceptable and repeatable results are obtained.

  • ✺STEP 6

    The second test is the Forced Vital Capacity (FVC) test, which measures how much air you can force out after taking a deep breath in.

    You need to perform at least three attempts, and the test will finish when you have three technically acceptable and repeatable results.

  • ✺STEP 7

    Your results will be sent back to the clinican that referred your for tests. They will be discussed with you during your follow up consultation. The results will help your doctor, nurse, or consultant make an accurate diagnosis.

Frequently Asked Questions.

  • Your doctor may recommend a spirometry test if you have symptoms of a lung condition, such as shortness of breath, wheezing, or a persistent cough. It helps in diagnosing conditions like asthma and COPD, and in monitoring the effectiveness of treatment.

  • You will receive information on how to prepare for your test when you receive booking confirmation.

    • Avoid smoking for at least an hour before the test.

    • Do not consume alcohol for at least four hours before the test.

    • Avoid heavy meals before the test.

    • Wear loose, comfortable clothing.

    • Follow any specific instructions given in your booking confirmation

  • The test itself usually takes about 15-30 minutes. However, you may need to spend additional time at the clinic for preparation and post-test discussions with your healthcare provider.

  • You should inform your healthcare provider about all medications you are taking. They will advise you on whether to continue or temporarily stop any medications before the test.

  • Spirometry results include measurements such as Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second. Your doctor can explain what your results mean at your follow up consultation.

  • There are a few contraindications to spirometry testing.

    The main risks involve high pressure in the chest affecting organs, blood flow, and lung expansion. These risks are usually low but should be considered alongside the clinical benefits of the test.

    Contraindications will be checked twice prior to teasting. The first will be via questionnaire at booking and again on the day of the test. It is important to contact us if you develop any contraindications before your appointment.
