Pulmonary function testing (PFT) is a process for assessing functional status of the lungs, for screening obstructive and restrictive lung disease, and for evaluating treatment response (e.g., medications, chest physical therapy). Spirometry, using a spirometer, is the most common of the pulmonary function tests and measures the amount (volume) and the speed (flow) of air that can be inhaled and exhaled. It is designed to measure changes in lung volume and can only measure lung volume compartments that exchange gas with the atmosphere.
In preparation for PFT, bronchodilator medications are typically held so that bronchodilator response can be assessed after baseline spirometry. For example, short-acting inhaled bronchodilators should not be used for 4 h prior to testing; long-acting beta-agonist bronchodilators are typically held for 12 h prior to testing.Notably, the spirometry procedure is highly dependent on individual effort and cooperation and, to...
