Each year we care for more than 300 children with cystic fibrosis, a life-threatening genetic disease that affects the lungs. Our Cystic Fibrosis Center is one of the largest national treatment centers accredited by the Cystic Fibrosis Foundation, and we strive to provide the highest quality care available anywhere.
One of the ways we measure our success in treating cystic fibrosis is the overall lung function of our patients. Beginning at approximately age six, children with cystic fibrosis regularly undergo lung function tests. One test — a measure known as forced expiratory volume in one second (FEV1) — is reported as a percentage of normal volume based on factors such as a patient’s age, gender and size.
The higher the percentage, the better the patient's lung function. By looking at the average lung function across all of our cystic fibrosis patients, we can assess the effectiveness of our treatment.
