When a patient crashes after intubation, the airway is often blamed.
Sometimes the tube is in the wrong place.
Sometimes the ventilator has changed the physiology.
Post-intubation collapse should trigger a fast, structured differential.
First, confirm oxygenation and tube position. Esophageal intubation, right mainstem intubation, tube obstruction, mucus plugging, and equipment failure must be considered immediately.
