Pulmonary Function Test

A pulmonary function test, also known as spirometry, is used to determine lung function. It is most commonly used to evaluate the breathing of people with asthma, emphysema, and acute or chronic lung infections. It can also be used to help in diagnosing/treating patients with cough. This will be ordered by your physician, and the pulmonary lab will contact you to set this up …..the results will be reviewed by your doctor (and you will be called or ask to return for follw-up appointment)

Below is a brief description of some of the procedure, but the details will be reviewed with you by the personnel doing the testing (which will depend on the location of the test – either Baylor Medical Center at Irving or Las Colinas Medical Center)

You will be called directly by the lab doing the testing so that you can schedule it. You will then be called (or asked to make appt) regarding the results.

General description:

  • Nose clips are placed on the nose (to prevent air from escaping through the nostrils) and you will be instructed to breathe into a flexible tube called a spirometer.
  • Various breathing patterns are tested, such as breathing normally, exhaling as fast as possible after inhaling normally, or inhaling and exhaling deeply.
  • You may also breathe specific quantities of helium, nitrogen, or pure oxygen.

Risks:

  • Usually none.
  • Some people with respiratory disorders or infections may experience varying levels of shortness of breath or a temporary worsening of their condition.
  • Most people recover without additional problems once the testing is stopped.
  • Sometimes medications are used to assist your breathing during the testing.
