PhysiciansDiagnostic testing

A number of different tests might be appropriate to determine how best to improve your breathing.

  • Pulmonary function tests measure the flow of air and the volume of air in your lungs.
  • Pulse oximetry shows how much oxygen is in your blood (oxygen saturation). This may be done at rest as well as during and after exercise.
  • Arterial blood gas tests measure levels of oxygen and carbon dioxide in your blood.
  • Chest x-rays show the size and shape of your lungs. They can also show certain problems in the lungs.
  • CT (computed tomography) scans produce images of lungs that are more detailed than x-rays.
  • 6-minute walk
  • Pulmonary stress test
  • Maximum ventilatory oxygen testing
