Helmet Noninvasive Ventilation vs. High-flow Nasal Cannula in Moderate-to-severe Acute Hypoxemic Respiratory Failure
Italy110 participantsStarted 2020-10-13
Plain-language summary
Helmet noninvasive ventilation and high-flow nasal cannula are novel tools for the first-line treatment of acute hypoxemic respiratory failure. Compared to face-mask noninvasive ventilation in randomized trials, both have improved clinical outcome of patients with moderate-to-severe hypoxemic respiratory failure.
As compared to high-flow nasal cannula, helmet noninvasive ventilation improves oxygenation, reduces inspiratory effort, respiratory rate and dyspnea. Whether these physiological benefits are translated into improved outcome remains to be established.
The investigators designed a randomized trial to establish whether first line treatment with Helmet noninvasive ventilation is capable of increasing the number of 28-day respiratory-support-free days, as compared to high-flow nasal cannula in patients with moderate-to-severe acute hypoxemic respiratory failure.

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.
