Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. [1]
Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.

[18] In May 2013, the American Thoracic Society issued the first treatment guidelines for EIB, recommending use of "a short-acting β2-agonist before exercise in all patients with ...
He assembled a cylindrical tube partially filled with water, with an open water source entering the bottom of the cylinder. He occluded his nostrils, inhaled through an outlet at the top of the cylinder and measured the volume of air displaced by water. Nowadays, this technique is very important in determining parameters of lung volume.
Pulmonary drug delivery is mainly utilized for topical applications in the lungs, such as the use of inhaled beta-agonists, corticosteroids and anticholinergic agents for the treatment of asthma and COPD, the use of inhaled mucolytics and antibiotics for the treatment of cystic fibrosis (CT) and respiratory viral infections, [1] and the use of inhaled prostacyclin analogs for the treatment of ...
An incentive spirometer is a handheld medical device used to help patients improve the functioning of their lungs.By training patients to take slow and deep breaths, this simplified spirometer facilitates lung expansion and strengthening.
