Comparing Two Devices That Measure Breathing During Exercise
This study compares two devices (Calibre and COSMED) that measure how your lungs work during exercise. The trial helps researchers understand if these devices give similar results, which could improve how doctors test breathing and heart function.
Summary written for real people, not researchers, by Clin2.

- You are between 18 and 55 years old
- You speak English and can understand study information
- You do not have active heart problems like recent heart attacks, chest pain, or fainting
- Your asthma is well-controlled, and your blood oxygen is at least 85% when resting
- Your blood pressure is not severely high (below 200/120 mm Hg at rest)

This study is developing and checking how well a pre-surgery evaluation system (using objective body measurements) can predict and help around the time of anesthesia and surgery. You might be asked to complete a clinic screening and provide consent, as long as your results fit their safety and screening thresholds.
This observational study does not change your treatment. It collects results from your usual cardiopulmonary exercise test (CPET) to help validate better ways to estimate VO2max, a measure of exercise capacity.
This study uses breath analysis and heart/electrical heart testing to look at how stiff the arteries are in people with long-term lung conditions. It may help researchers better understand lung disease effects on the cardiovascular system.
This study compares two different exercise test methods to see which works better for men and women with heart disease. The goal is to find a test that can help doctors design better exercise programs for you.
This study measures how you breathe using two methods: tracking carbon dioxide in your breath and measuring lung function with a spirometer (a breathing device). Boston Scientific is testing these measurement approaches to understand how well they work together.
This study tests if breathing in carbon dioxide can help doctors see how well blood flows to your heart muscle. It is for people with known or suspected heart disease who already had a scan showing reduced blood flow.
