Plethysmography

Plethysmography is a test used to measure how much air your lungs can hold and how well they function. During the test, you sit inside a small, sealed chamber, where you breathe normally for a short period. The equipment records changes in pressure inside the chamber as you breathe, allowing doctors to determine lung capacity and airflow rates. This information helps identify any breathing problems or diseases, providing valuable insights into your lung health. It’s a safe and effective way to assess respiratory function.
