Can always send patient home and tell them to come back when having symptoms, but this delays diagnosis. OF PULMONARY FUNCTION TESTS Spirometry Spirometry is the measurement of the air mov - ing in and out of the lungs during various res-piratory maneuvers.2 It allows one to deter-mine how much air can be inhaled and exhaled, and how fast. The most commonly performed PFT’s include … Figure 252-2. FVC is decreased in both obstructive and restrictive disease, so usually need to obtain lung volumes to see if restrictive component present (increased TLC). Pulmonary Function Testing (PFT) is a type of testing that measures the person’s respiratory system functionality. PFT = pulmonary function testing. Example of someone grabbing trachea—causes problems w/ inspiration and expiration = fixed obstruction. The test also measures how forcefully one can empty air from the lungs.

This is not a complete list, just some of the most common diseases that should be on your differential for obstructive lung disease. Physiologic abnormalities that can be measured by pulmonary function testing include obstruction to airflow, restriction of lung size, and decrease in transfer of gas across the alveolar–capillary membrane. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders. The Dterature on pulmonaryfunction testing insareoldo­ sis is critically reviewed. The most basic test is spirometry. The tests measure lung volume, capacity, rates of flow, and gas exchange.
