Pulmonary Medicine

Special Testing


A technique to look inside the airways and lungs to help determine the cause of your child's chronic lung problems. Cultures of the lungs can be performed to check for infection. This test is usually done as an outpatient, but requires sedation medicines.


These sleep studies help your doctors determine if your child has problems breathing while asleep. Special equipment measures the movement of oxygen and carbon dioxide in and out of the lungs, the stage of sleep, heart rate, and other parameters. These studies require an overnight inpatient visit.

Cardiopulmonary Exercise Testing

These studies may help determine the cause of breathing problems that occur during exercise. The study usually involves your child exercising on a treadmill or exercise bicycle, after which breathing tests and heart tests are performed. The results are jointly interpreted by one of the pulmonary doctors and one of the cardiology doctors.

Sweat Testing

This test is used to diagnose Cystic Fibrosis. A chemical is applied to the arm to stimulate the sweat glands to be more active. Sweat is then collected for 30 minutes, and the amount of salt in the sweat is then measured. This test is not painful, but produces a tingling 'pins and needles' feeling in the arm.

Radiological Testing

Tests such as chest x-rays, computed tomography (CAT) scans and ventilation-perfusion scans can help your doctor understand the anatomy and function of your child's lung problems. Other tests such as a barium swallow or milk scan (scintiscan) can help determine the presence or cause of gastroesophageal reflux.
