Feeling short of breath is alarming, especially when you don’t know the cause. You may breathe normally while sitting at your desk but struggle to catch your breath when going about your daily routine or exercising.
Tests such as a pulmonary stress test and pulmonary monitoring can provide valuable information about how your lungs respond to different situations. But how do you know which test you need?
At Respacare in Bridgewater, New Jersey, our sleep pulmonologists, Dr. Nehal Mehta and Dr. Prashant Patel, recommend testing based on your symptoms, health history, and what we need to learn about your breathing.
Understanding the difference between these tests can help you know what to expect.
Pulmonary stress testing is an exercise-based test that evaluates how your lungs, heart, and muscles work when your body is physically stressed. Exercise increases your body’s need for oxygen, requiring your lungs and cardiovascular system to work harder.
During the test, you ride a stationary bike or walk on a treadmill while breathing through a mask. The test measures factors such as oxygen use, breathing, and your heart’s response to exercise.
Your appointment may last about 90 minutes, although the actual exercise portion is typically much shorter. The test can help identify problems that may not show up when resting.
Pulmonary monitoring provides information about your breathing and other vital signs during normal daily activities. Instead of testing you under controlled exercise conditions, remote monitoring allows us to collect information from the comfort of your home.
Health monitoring sensors worn under your clothing collect data and transmit it to a home health hub, which then sends information to us. Depending on your monitoring plan, this may provide information such as oxygen levels, breathing patterns, and heart rate over time.
This approach is especially helpful when symptoms come and go or aren’t present during an office visit. It can also help us see how you’re responding to treatment and identify changes in your condition sooner.
Both tests can provide important information about your lung health, but they answer different questions.
A pulmonary stress test looks at how your body responds when you exercise. By increasing your body’s demand for oxygen, it can help reveal problems that occur specifically during physical exertion.
Pulmonary monitoring looks at your breathing over time during everyday life. It can help identify changes or patterns we might not capture during a single office visit or exercise test.
Think of it this way: A pulmonary stress test gives us a snapshot of how your body responds to a controlled challenge, while pulmonary monitoring can provide a more continuous picture of what’s happening throughout your normal routine.
The right test depends on your symptoms and what your doctor is trying to find. If your shortness of breath primarily occurs during exercise, a pulmonary stress test may provide useful information. If your symptoms occur at different times throughout the day, during sleep, or during normal activities, you may benefit from pulmonary monitoring.
You may also benefit from testing after starting treatment to help determine whether it’s working and prevent worsening symptoms. In some cases, your doctor may recommend both tests to get a more complete picture of your lung and heart function.
Persistent or unexplained shortness of breath is concerning and needs an evaluation. When and how your symptoms occur can help us determine what type of testing you need.
