body plethysmography

Body plethysmography is a medical test used to measure how well your lungs work. During the test, you sit in a sealed chamber and breathe through a mouthpiece. By measuring changes in pressure and lung volume as you breathe, doctors can determine the total amount of air your lungs can hold and how easily air moves in and out. This helps diagnose lung conditions like asthma or COPD, especially when standard tests might not give a complete picture. It provides accurate, detailed information about lung capacity and airflow, aiding in proper diagnosis and treatment planning.
