Sudden Collapse After a Bedside Procedure

You are leading the care team in the pediatric intensive care unit. A 7-year-old child weighing 22 kg is being treated for a serious infection. A left subclavian central venous catheter was placed 15 minutes ago because the child's peripheral access had become unreliable. One peripheral IV remains functional.

The child suddenly develops severe respiratory distress and becomes unresponsive. A nurse, respiratory therapist, pediatric critical care clinician, and medication clinician are present. Oxygen, bag-mask equipment, pediatric airway equipment, IV and IO supplies, emergency medications, a manual defibrillator, and equipment for emergency chest decompression are immediately available.
