Intubation strategies for adults with acute hypoxemic respiratory failure
Official title: IntHyx : Intubation Strategies for Patients With Acute Hypoxemic Respiratory Failure
Run by University Hospital, Angers · NCT07189078 · Data updated 2026-11-12
This trial will test two different rules for when to intubate adults with acute hypoxemic respiratory failure to see which approach keeps patients safer while avoiding unnecessary mechanical ventilation.

Is this trial a fit for you?
✓Likely a good fit
Adults admitted to an ICU within the last 24 hours with acute hypoxemic respiratory failure requiring high-concentration oxygen (≥10 L/min) or high-flow oxygen (FiO2 ≥50%) to maintain SpO2 ≥92% and who can provide consent or have a proxy.
✕Probably not a fit
Patients with acute hypercapnic respiratory failure, cardiogenic pulmonary edema, recent invasive ventilation, neuromuscular disease, immediate need for intubation, or other listed exclusions are unlikely to benefit from this protocol.

What this trial studies
This randomized interventional trial enrolls adults admitted to the ICU within 24 hours who have acute hypoxemic respiratory failure meeting prespecified oxygen requirements. Participants are randomized to a restrictive intubation strategy or a liberal intubation strategy and managed according to the assigned protocol. The trial compares timing and indications for endotracheal intubation, with outcomes focused on need for invasive mechanical ventilation, complications related to ventilation and clinical status. The goal is to identify an approach that balances risks of delayed intubation against harms of unnecessary invasive ventilation.
Why it matters
Potential benefit: If successful, the trial could reduce unnecessary intubations and related complications while preventing harm from delayed ventilation, improving overall patient outcomes.
How similar studies have gone: Some observational studies and smaller trials have examined timing of intubation, but randomized comparisons of restrictive versus liberal intubation strategies remain limited, making this approach relatively novel in rigorous RCT form.
