Pulmonary and Critical Care

Pulmonary Function Tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and choose the treatment of certain lung disorders.

There are two sorts of disorders that cause problems with air occupation and out of the lungs:

• Obstructive. this is often when air has trouble flowing out of the lungs thanks to airway resistance. This causes a decreased flow of air.

• Restrictive. this is often when the lung tissue and/or chest muscles can’t expand enough. This creates problems with air flow, mostly thanks to lower lung volumes.
