Study summary

Acute hypoxemia is common and deadly in resource variable settings. While studies in high income countries (HICs) have indicated a possible benefit to high flow oxygen as compared with standard flow oxygen, rigorous studies in low or lower middle income countries (LMICs) have not been performed. Studies in sepsis have demonstrated that interventions that improve outcomes in one context may actually be neutral or harmful in a different context.

The goal of this study is to test whether high flow oxygen results in better outcomes for hypoxemic adult patients, as compared with standard flow oxygen, in five LMIC hospitals. The main questions it aims to answer are:

  1. For hypoxemic adults in these LMIC study settings, does high flow oxygen or standard flow oxygen result in lower mortality?
  2. What are the facilitators and barriers to using high flow oxygen in these settings?
  3. Does high flow or standard flow oxygen use more oxygen?

Participants will be randomized to receive either high flow oxygen through a large nasal cannula, or to receive standard flow oxygen, through nasal cannulas, face masks, or non-rebreather masks. Researchers will compare the outcomes for the two groups, to see if one group of patients has better outcomes than the other.

The study will also examine how much oxygen is used by the two patient groups, as well as other factors relevant to the feasibility of implementation of high flow oxygen in these sites.

Plan to share: No — IPD will not be shared with other researchers for the trial overall. IPD is owned and managed by each of the sites for the trial, in accordance with the data protection requirements of each country where the sites are located.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2023 (actual). Primary completion is estimated for Oct 2026, 36 months after the start.

Of 321 non-industry interventional studies with no phase under Hypoxia, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 27. This study's planned 36 months is above that.

Counting every sponsor, half of 351 studies reached it within 12 months; a quarter within 3 and three quarters within 27.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 15, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
