This is the amount of air expired during the first, second, and third seconds of the FVC test. Forced expiratory flow FEF. This is the average rate of flow during the middle half of the FVC test. Peak expiratory flow rate PEFR. This is the fastest rate that you can force air out of your lungs. Normal values for PFTs vary from person to person.
The amount of air inhaled and exhaled in your test results are compared to the average for someone of the same age, height, sex, and race. Results are also compared to any of your previous test results. If you have abnormal PFT measurements or if your results have changed, you may need other tests. There are many different reasons why pulmonary function tests PFTs may be done.

Ann Spirometry is a test that is part of the testing done during a pulmonary function study but it is also done as a single test.
John A spirometer is a device used to perform spirometry. Lyn Spirometry is a type of pulmonary function test used in conjunction with other findings to diagnose certain lung conditions such as COPD, asthma , and pulmonary fibrosis.
Leon Chronic Obstructive Pulmonary disease COPD is a clinical diagnosis that should be based on careful history taking, the presence of symptoms , and assessment of airway obstruction. It has major uses in COPD and can help to: Confirm the presence of airway obstruction Provide an index of disease severity Help differentiate COPD from asthma Detect COPD in subjects exposed to risk factors , predominantly tobacco smoke Enable monitoring of disease progression Help assess the individual's response to therapy Spirometry has many other applications in assessing and managing respiratory disease.
