DAS 2025 — Difficult Airway Society 2025 Guidelines for Management of Unanticipated Difficult Tracheal Intubation in Adults

Use a planned linear rescue strategy from tracheal intubation to supraglottic-airway ventilation, facemask ventilation, and emergency front-of-neck airway; maximize first-attempt success, continue oxygen delivery throughout airway management, use videolaryngoscopy whenever possible, confirm ventilation with sustained waveform capnography, and limit laryngoscopy attempts to 3 plus one final attempt by a more experienced operator.
