1. Pulmonary function test

2. What are PFT's? Pulmonary Function Tests are performed to measure a patient's lung volume, capacity, flow rate, and gas exchange. This allows medical professionals to obtain an accurate diagnosis and determine the best course of medical intervention for the patient

3. Types of Lung Disorders Obstructive Lung Diseases : Obstructive lung diseases include conditions that make it difficult to exhale air out of the lungs. This results in shortness of breath that occurs from narrowing and constriction of the airways and, ultimately, causes the patient to have decreased flow rates. Restrictive Lung Diseases : Restrictive lung diseases include conditions that make it difficult to fully fill the lungs with air during inhalation. When the lungs aren't fully able to expand, it causes the patient to have decreased lung volumes.
