800 ARDS patients to be studied for better treatment insights
NCT ID NCT07186140
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study will follow 800 adults with acute respiratory distress syndrome (ARDS) in a Korean hospital to learn about their symptoms, treatments, and outcomes. Researchers will collect data from medical records and monitor how different ventilator settings affect recovery. The goal is to improve understanding of ARDS and guide future care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help doctors better understand ARDS and improve treatment strategies for future patients.
- What could go wrong
- This is an observational study, not a treatment trial. It will not directly benefit participants and may not lead to immediate changes in care.

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 years. * Receiving respiratory support with one of the following: * High-flow nasal oxygen (HFNO) at a flow rate ≥ 30 L/min, * Noninvasive ventilation (NIV) with positive end-expiratory pressure (PEEP) of ≥ 5 cm H₂O, or * Invasive mechanical ventilation with PEEP of ≥ 5 cm H₂O. * Within 48 hours before or after eligibility screening, the following criteria must be met: * PaO₂/FiO₂ ≤ 300 mmHg under the above respiratory support. * Bilateral opacities on chest radiograph or computed tomography, not fully explained by effusions, lobar/lung collapse (atelectasis), or pulmonary nodules/masses. * Respiratory failure not fully explained by cardiac failure or fluid overload; when no clear ARDS risk factor is identified, an objective assessment (e.g., echocardiography) is required to exclude hydrostatic edema. Exclusion Criteria: * Refusal of informed consent by the patient or a legally authorized representative. * Chronic respiratory failure, defined as: * Patients receiving long-term oxygen therapy or home mechanical ventilation (except for CPAP used solely for obstructive sleep apnea), or * Outpatients with PaCO₂ \> 60 mmHg. * Diffuse alveolar hemorrhage. * Interstitial lung disease. * Moribund patients expected to survive \< 24 hours. * Patients expected to require high-flow nasal oxygen or mechanical ventilation for \< 48 hours. * Patients with a decision to withhold life-sustaining treatment (except those for whom full support is provided other than cardiopulmonary resuscitation).
