Pulmonary Function Testing (PFT) made simple

Several factors affect lung volumes; some can be controlled, and some cannot be controlled. Lung volumes vary with different people as follows: A person who is born and lives at sea level will develop a slightly smaller lung capacity than a person who spends their life at a high altitude. This is because the partial pressure of oxygen is lower at higher altitude which, as a result means that oxygen less readily diffuses into the blood… WebThe peak expiratory flow (PEF) is the peak flow occurring during exhalation.
