Frequently Asked Questions About Pulmonary Function Testing in NYC

patient undergoing pulmonary function testing in NYCA Pulmonary Function Test, also known as a PFT, is a noninvasive test that helps a doctor assess how your lungs are functioning. This type of test has evolved over the years in terms of what’s involved with performing the test and where it can be done. Traditionally, a lab environment was where PFTs were performed. Today, new technology allows patients to undergo pulmonary function testing right from the doctor’s office. It involves performing a series of breathing maneuvers, done by simply blowing into a handheld device that’s connected to a specialized machine. It is safe, quick, and easy to perform.

In this blog, experienced Manhattan lung specialist, Dr. Marc Bowen, will address the most commonly asked questions about pulmonary function testing.

Why would I need to undergo pulmonary function testing?

There are a number of reasons why a pulmonary function test might be recommended – ranging from an initial diagnostic evaluation, to following the progression of an existing lung disease, or to determine clinical response to treatment. In addition, pulmonary function testing is commonly required as part of a preoperative surgical evaluation. Prior to bariatric, thoracic, cardiac, vascular or major intra-abdominal surgery (among other types of surgery), a PFT is often needed to assess how well your lungs are functioning, to be able to identify and optimize any physiologic derangements, in order to reduce perioperative pulmonary risks.

Furthermore, there are a number of symptoms that might warrant pulmonary function testing as well. These include:

What does a pulmonary function test reveal?

Pulmonary function testing reveals multiple things, including:

  • Lung volumes – how much air the lungs can hold at any given time throughout the respiratory cycle
  • Lung capacity – how much air the lungs can exchange at the end of maximal inspiration (after inhaling as deeply as possible)
  • Airflow rates – how quickly you can move air in and out of the lungs
  • Gas exchange – how well your lungs are able to transport gas across lung tissue, into the circulatory system, and back out again

Based on the information gathered during a PFT, Dr. Bowen can diagnose new lung disorders or evaluate the progression of existing lung conditions, such as:

  • Asthma
  • Chronic obstructive pulmonary disease, including chronic or asthmatic bronchitis and other smoking-related diseases
  • Emphysema
  • Pulmonary fibrosis
  • Inflammatory lung diseases
  • Pulmonary vascular disorders
  • Neuromuscular disorders

What can I expect during pulmonary function testing in NYC?

Does a pulmonary function test hurt?

Pulmonary function testing is noninvasive and it does not involve any needles or painful aspects. However, certain parts of the test will require you to blow as hard as you can into the handheld device, which can cause you to cough, or even feel out of breath or light headed for a short period of time. This is not common and usually is not problematic.

How do I prepare for my PFT?

Dr. Bowen will provide specific instructions about how to prepare for the test. Some of the most common inquiries from patients include questions about eating and taking medications. You do not need to have an empty stomach to undergo pulmonary function testing, but you should not eat a heavy meal right before taking the test. In some cases, your doctor may ask you to not take your bronchodilator inhalers on the day of the test. Patients should wear loose-fitting clothing that does not restrict breathing.
