The test measures how quickly and how much air you can breathe in and out.1 It is part of the testing done with full pulmonary function testing which may include other assessments (see below).

Depending on the clinical situation, additional investigations may be indicated such as: Sputum culture – if sputum is purulent and persistent (to identify organisms). The FEV1 is calculated as a percentage of the FVC (FEV1/FVC). The findings of the spirometry test can be used in the following ways 2: To find out whether or not you have COPD: If your FEV 1 /FVC ratio is less than 0.7, you likely have COPD.

Spirometry with an obstructive pattern after the administration of bronchodilators is required for the diagnosis of COPD. If COPD seems likely then perform post bronchodilator spirometry to confirm the diagnosis (2): presence of a post bronchodilatory FEV1/FVC < 0.7 confirms persistence airflow limitation and thus a diagnosis of COPD in patients with appropriate history and symptoms ; consider alternative diagnoses or investigations in: A spirometry test is a tool you and your doctor can use to determine which COPD treatments are right for you at each stage of the disease.

As many as 12 million Americans have COPD and haven’t been diagnosed. This test combines spirometry with the use of a bronchodilator, … Marijuana smoke has many of the same chemicals as tobacco, but the link between marijuana use and COPD is not as clear. However, diagnosing the disease is just one way this test can be helpful for COPD patients.

Pulmonary function tests (PFTs) are used to assess various aspects of your lung function. Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease. This tells your doctor how your test results compare with someone of the same sex, age, race, and height and is presented as “percent predicted.” If your FEV1 is less than 80% of predicted, it means that your lungs are not working as well as would be expected for someone of your sex, age, race, and height.2. Your FEV1is less than 30 percent of normal predicted values or less than 50 percent with chronic respiratory failure.
