New trial tests CPAP combo to save lives in breathing crisis
NCT ID NCT06213168
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two oxygen therapy strategies for adults in the ICU with severe breathing failure. One group gets high-flow oxygen alone, the other gets high-flow oxygen plus CPAP sessions. The goal is to see if adding CPAP reduces the need for a breathing tube and lowers the risk of death within 90 days. About 1,084 participants will be enrolled.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Continuous positive airway pressure (CPAP) and high-flow nasal cannula oxygen therapy
- What this could lead to
- If it works, this could show that adding CPAP to high-flow oxygen helps more people survive severe breathing failure without needing a breathing tube.
- What could go wrong
- This is a large trial, but earlier studies on CPAP for this condition have had mixed results. The treatment may not lower death rates and could cause discomfort or delays in needed intubation.

Inclusion Criteria: 1. Adults (≥ 18 years old) 2. Admitted in the ICU for ≤ 24 hours 3. De novo hARF defined by the three following criteria: 1. Respiratory rate \> 25 breaths/min or signs of respiratory distress such as labored breathing or paradoxical inspiration 2. PaO2/FiO2 ≤ 200 mmHg under HFNC with flow ≥ 45 L/min, actual FiO2 being considered. 3. Uni or bilateral pulmonary infiltrate on chest X-ray or CT scan 4. Informed consent from the patient or her/his next of kin or another substitute decision maker, or inclusion procedure in emergency if the patient is unable to consent Exclusion Criteria: 1. Refusal of study participation by the patient or the proxy 2. Anatomical factors precluding the use of a nasal cannula or CPAP 3. Long term oxygen 4.
