Pulmonary Function Test

Alternate Names : Spirometry

Pulmonary Function Test | Preparation & Expectations | Results and Values

What do the test results mean?

Normal values for the match test, the FEF, and the PER tests are as follows:

match test: the flame is blown out easily

FET test: all the air in the lungs is expelled in two to five seconds

PEF: the value should be 80% of the predicted normal value

A person's spirometer readings from the MVV, FVC, and FEV1 are compared with values from a standard table. The table provides values based on a person's age, sex, and body size. Based on the patterns seen, the provider can diagnose different lung problems.

Abnormal results may indicate the following:

changes in lung function due to medications

exposure to contaminants in the air

lung disease
