An Adaptive Randomized Controlled Trial (RCT) Comparing High-flow Nasal Cannula Oxygen and Noninvasive Ventilation to Standard Oxygenation in Non-selected Intensive Care Unit Patients Admitted for Hypoxemic Acute Respiratory Failure: The KISS Trial (Key Oxygenation Interventions in Surgical and Non-Surgical Patients)
The goal of this clinical trial is to determine whether one of the two oxygenation or ventilation strategies (NIV and/or HFNO) is superior to standard oxygen to reduce 28-day mortality rate in hypoxemic acute respiratory failure (ARF) patients.
• Adult (age ≥ 18 years)
• A diagnosis of hypoxemic ARF occurring defined as the presence and persistence for more than 30 minutes of hypoxemia (defined by a partial oxygen pressure \<60 mm Hg when breathing room air or \<80 mmHg when breathing 15 L/min of oxygen or a peripheral oxygen saturation \[SpO2\] ≤90% when breathing room air and/or a PaO2(partial pressure of oxygen)/FiO2 ratio \< 300 mmHg plus either \[1\] a respiratory rate higher than 30/min or \[2\] clinical signs suggestive of intense respiratory muscle work and/or labored breathing, such as use of accessory respiratory muscles, paradoxical motion of the abdomen, or intercostal retraction).
