HFNO Versus Face Mask for Cerebral Oxygenation During Procedural Sedation
2026년 7월 16일 업데이트: AHMET AKSU, Firat University
Effects of High-Flow Nasal Oxygen Versus Conventional Face Mask Oxygen on Cerebral Oxygenation During Out-of-Operating-Room Procedural Sedation: A Prospective Randomized Controlled Trial
This prospective randomized controlled trial aims to compare the effects of high-flow nasal oxygen (HFNO) and conventional face mask oxygen therapy on cerebral oxygenation during procedural sedation performed outside the operating room.
Adult patients undergoing elective diagnostic or interventional procedures under procedural sedation will be randomly assigned to receive either HFNO or conventional face mask oxygen.
Regional cerebral oxygen saturation will be continuously monitored using near-infrared spectroscopy (NIRS), while sedation depth will be assessed using the Patient State Index (PSI, SedLine) and the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale.
Secondary outcomes include peripheral oxygenation, ventilation parameters, arterial blood gas values, airway interventions, hemodynamic variables, and patient and practitioner satisfaction.
