Pulmonary Function Tests

Spirometry measures the lung functions by determining the amount of air that enters and exits the lungs. This test is used to diagnose pulmonary conditions such as asthma, chronic pulmonary disease, and pulmonary fibrosis.
Lung Volume Measurement
The test measures the size and volume of air in the lungs when the person breathes. The test is performed in the glass booth in which the patient breathes into a tube connected to the computer that measures the lung volume.
Gas Diffusion Capacity
Gas diffusion tests measure the exchange of gas between the lungs and the bloodstream. Its purpose is to measure how effective the lung delivers oxygen to the red blood cells and the bloodstream transferring carbon dioxide to the lungs.
Methacholine Challenge Test
Methacholine Challenge Test measures the lung functions after breathing in specific chemicals. The purpose for the use of the chemical is to determine whether the patient has asthma and the effectiveness of the asthma medicine. The types of chemicals used during testing include methacholine and histamine.
Pulmonary Stress Test
The test involves performing a six minute walk test to evaluate the patient's respiratory function. It identifies the symptoms of the patient that occurs during the test such as shortness of breath and wheezing.
Cardiopulmonary Exercise Test
This technique measures the reaction of the heart and lungs during exercise performed on the stationary bike. During the process, the test measures the patient's respiratory function, the amount of oxygen needed, and the speed and efficiency of the heart beat.
Indirect Calorimetry
This test measures the metabolic energy consumption and concentrations of oxygen and carbon dioxide.
