Pulmonary Function Test (PFTs)

This is a simple function test to determine how well your lungs take, hold and receive air. PFTs are performed to diagnose certain kinds of lung disease such as asthma, bronchitis and emphysema. They can also be performed to determine if environmental contaminants or medications may be affecting one’s lung function.

Using an instrument called a spirometer, you will breathe into a mouthpiece. The spirometer will document how much time it takes for you to inhale and exhale air over a set period of time. The test takes 20-30 minutes and may be repeated during follow up visits.

Patients may experience some lightheadedness and/or shortness of breath since the PFT requires forced and rapid breathing.

Test results are based on patient history, medical history and the PFT results. Your doctor will thoroughly discuss your test results, determine if any treatment is necessary and if needed, create a personalized treatment plan to meet your specific needs.

Cardiopulmonary Stress Test

A Cardiopulmonary stress test (CP stress test) is an exercise test that uses a special bicycle called an ergometer, and state-of-the-art computer equipment to measure how well your lungs work as you exercise, as well as take an electrocardiogram (ECG) of your heart. This test will reveal if the heart and/or lungs has any problems while exercising, which will help your physician determine a more accurate diagnosis and create an suitable treatment plan for you.

As you are riding this specialized bicycle, you will breathe into a breath analyzer, which measures the exchange of gas to your lungs. ECG wires will also be attached to your chest to record how well the heart functions as you exercise. We will continually take your blood pressure throughout the test as well.

Starting out slow, the resistance will steadily be increased until you are unable to continue or the maximum predicted heart rate is achieved.

The CP stress test along with your patient and medical history will help your physician make an accurate diagnosis and determine the best treatment option to meet your needs.
