What tests will be used to diagnose bronchospasm?

Your provider may recommend certain assessments to determine how well your lungs are functioning. These tests may include:

  • Pulse oximetry. A device is placed on your finger or ear to measure how much oxygen is in your blood.
  • SpirometryA spirometer is a device that measures the force of air as you breathe in and out of a tube.
  • Lung volume assessment. This tells your provider how much air your lungs can hold.
  • Lung diffusion capacity. During this test, you breathe into a tube to determine how well oxygen is transferred or diffused between your lungs and your blood.
  • Arterial blood gas tests. This test measures the amount of oxygen and carbon dioxide in your blood. It also measures the pH level of your blood.
  • Eucapnic voluntary hyperventilation. Your healthcare provider may use this test to check for exercise-induced bronchospasm. During this assessment, you breathe in a mixture of oxygen and carbon dioxide, which mimics breathing during exercise. If it has a negative impact on your lungs, then you probably have exercise-induced bronchospasm.

In addition to the breathing tests, your healthcare provider may also take imaging tests to look for infections or other lung problems. These tests could include chest X-rays and CT scans.
