Pulmonary Function Tests

Lung Function Tests

Pulmonary function tests are a series of tests used to provide your doctor with information about lung function. These tests give your doctor measured data about your ability to breathe and how well your lungs work in providing you with oxygen.

There are several types of pulmonary function tests, including:

  • Body plethysmography

  • Functional residual capacity (FRC)
  • Residual volume
  • Total lung capacity
  • Forced expiratory volume (FEV)
  • Forced expiratory flow (FEF)
  • Peak expiratory flow rate (PEFR)
