Pulmonary function tests are used:

  • To help diagnose and evaluate lung disease
  • To determine the appropriateness and effectiveness of new and current treatments
  • To measure how severely the lung is damaged

In addition, pulmonary function tests are important to assess the health of a person's lungs before chest surgery. 

There are two general types of pulmonary function tests:

  • Ventilation tests
  • Arterial blood gas studies

Before having a ventilation type of pulmonary function test, it is best to avoid the following activities:

  • Eating a heavy meal or solid food for four to six hours
  • Smoking for four hours
  • Exercising for four hours

In addition, unless advised to do so by your doctor, you should not take any medication for four hours before the test.
