Questions about this trial
What is this clinical trial studying?
A study testing High-Flow Nasal Oxygen / Non-invasive ventilation / Standard oxygen in people with ICU and Extubation, run by Poitiers University Hospital at 2 sites in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 31 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Arnaud W. THILLE, PUPH (+33 5 49 44 38 54, arnaud.thille@chu-poitiers.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Patient respiratory effort and tidal volume (Vt) (time frame: 1h20). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04036175, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2019; AzTrials last refreshed its copy on 8 Nov 2026.
