Can combining two oxygen devices help patients breathe better?
NCT ID NCT07521254
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two ways of giving breathing support to adults with acute respiratory failure in the ICU. One group gets standard noninvasive ventilation (a mask that helps breathing), while two other groups get that plus a high-flow nasal cannula (a device that delivers warm, moist oxygen through the nose) at different times. The goal is to see if the combination improves oxygen levels and comfort more than the mask alone. The trial will include 75 patients and track results over 24 hours.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- High-flow nasal cannula (HFNC) device and noninvasive ventilation (NIV) device
- What this could lead to
- If successful, this could show that combining two breathing support methods helps patients with acute respiratory failure breathe easier and need less time on a ventilator.
- What could go wrong
- This is a small, early-stage study with only 75 participants, so results may not apply to all patients. The devices are already in use, so no major new risks are expected, but individual responses vary.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥18 year of both sexes. • Diagnosed with Acute Respiratory Failure (ARF) defined as the combination of a PaO2/FiO2 ratio \< 300 after 15 minutes of conventional oxygen delivered through a face mask, with a FiO2 at least of 50% and respiratory rate \> 30 breaths/min. Exclusion Criteria: * Chronic respiratory disease * Cardiogenic pulmonary edema * Life-threatening arrythmias * Hemodynamic instability requiring vasopressors * Facial abnormalities preventing NIV or HFNC application * Glasgow coma score of ≤ 12 points (Teasdale et al. 1974) * Agitated patients characterized by RASS score (Richmond Agitation Sedation Scale) ≥ +2 * Patients who needed immediate endotracheal intubation * Pregnant patients
