The staff of Ascension Crittenton’s Pulmonary Function Laboratory performs a variety of breathing tests designed to diagnose and determine treatment for lung problems such as asthma and emphysema. Using new, state-of-the-art Radiometer and Jaeger equipment, technologists perform a variety of tests, including:

Spirometry - The most common pulmonary function test, this requires patients to blow into a tube while sitting in a chair. The test measures how much air patients breathe in and out and how fast they breathe.

Arterial Blood Gas - For this test, a blood sample is taken from an artery, and the levels of oxygen and carbon dioxide are measured. From this, technologists determine how effectively your lungs are getting oxygen into your blood and carbon dioxide out.

Cardiopulmonary Stress Testing - Patients perform progressively strenuous exercise. The exhaled air is measured to assess the cardiopulmonary function when compared to the expected outcomes for age, gender and height.

One of the body’s chief and most vital function is the ability to breath. At Ascension Crittenton, our Pulmonary Rehabilitation Program is designed to help people with lung disease maximize their quality of life. People who suffer lung diseases such as asthma, bronchitis, emphysema and pulmonary fibrosis or who have or have had volume reduction surgery or lung transplantation can all benefit from the program.

The Pulmonary Rehabilitation team at Ascension Crittenton consists of highly trained professionals, including nurses, exercise specialists and a registered dietitian. Using education and exercise, they work collaboratively to help patients achieve a high quality of life through recovery and reconditioning.

A referral from a physician is all that is needed to enroll in the program.
