Whole-Body Plethysmography

Whole-body plethysmography is a test used to measure the volume of air in the lungs and assess lung function. During the test, you sit inside a sealed chamber that looks like a small room. As you breathe normally, the device records changes in pressure inside the chamber, allowing healthcare professionals to determine how much air your lungs can hold and how well they work. It is commonly used to diagnose conditions like asthma or chronic obstructive pulmonary disease (COPD) and provides valuable information about respiratory health without discomfort.
