Step 1: Preparation Make the room, the physiology, and the rescue plan ready before medications are pushed. Step 2: Timeout Convert implicit assumptions into a shared, spoken airway plan. Step 3: Airway Execute deliberately: oxygenate, clean the view, identify landmarks, pass under vision, and prove placement. Step 4: Post-intubation The airway is not done when the tube passes. Make the tube safe and the patient stable.
