Spirometry / Flow Volume Loop
This is a fundamental and reliable lung function test that provides key information regarding airflow, in particular the FEV1.
What is a spirometry test used for?
Spirometry is ideal for the diagnosis and management of asthma and asthma symptoms through serial lung testing, as well as monitoring patients with COPD.
How is a spirometry test performed?
During a spirometry test, the patient breathes into a device called a spirometer. Here, patients are instructed to take an individual deep inhalation, and then a forced exhalation as quickly and completely as possible. This same process is performed again after having salbutamol. This component of the test is useful in differentiating asthma from COPD.Â
For patients with asthma, the FEV1 usually normalises with salbutamol, while for patients with COPD, the FEV1 will at most partially normalise. This is a common area of misunderstanding. It is important to remember that most patients with COPD will have a bronchodilator response (that’s how most of the inhaled therapies now available work); it simply is not complete.
Who needs a spirometry test?
Your GP may recommend spirometry if a patient has a chronic cough, is a smoker over 35 years old, experiences wheezing and shortness of breath, or has general lung misfunction symptoms or increased risks of condition development.
