In-Depth
What You Need to Know
Pulmonary function tests (PFTs), particularly spirometry, are routinely performed in allergy and immunology practices to evaluate lung function in patients with asthma, allergic bronchitis, and other respiratory conditions. During spirometry, the patient breathes into a mouthpiece connected to a device that records the volume and speed of air inhaled and exhaled, with key measurements including forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). A bronchodilator challenge may be performed as part of the test, where spirometry is repeated after the patient inhales a short-acting bronchodilator to assess reversibility of airway obstruction, which is a hallmark of asthma. Additional PFTs such as lung volume measurements and diffusion capacity tests may be ordered for more complex cases. Regular pulmonary function testing helps allergists track disease progression, assess treatment effectiveness, and adjust medication regimens to optimize respiratory health.
