Three-min Step Test and Exercise Desaturation Detection in Chronic Respiratory Insufficiency Patients

France27 participantsStarted 2022-04-15

Plain-language summary

The study project will aim at the evaluation of the occurrence of exercise desaturation phenomenon during two different modalities of exercise (walking and stepping condition). This study will allow determining the sensibility of the 3-minute step test to detect exercise desaturation, in comparison with the gold standard (6-minute walking test). The 3-minute step test could therefore appear as a complementary tool for the evaluation of oxygen desaturation in chronic respiratory disease.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients aged by 18 and more ; * Patient with an chronic obstructive respiratory insufficiency, confirmed by clinical and functional criteria ; * Patient with exercise-induced oxygen desaturation ; * Patient clinical ly stable, with no exacerbation period within the last 2 months before inclusion ; * Consent form signed by the patient. Exclusion Criteria: * Patient in exacerbation period at the inclusion time ; * Pregnant and breastfeeding women ; * Patient with orthopedic disorder that could limit the ability of stair climbing; * Any other disease that could influence exercise capacity of the patient or that could impair exercise test realization ; * Patient with law protection (guardianship or protection of vulnerable adults)

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
