The code is going smoothly. Good CPR is being delivered, and IVs have been established, allowing you to give first-round drugs. And although you don’t have the patient intubated, your partner is bagging effectively, you have good chest rise, and the capnography waveform is textbook. Suddenly, the patient’s entire stomach contents erupt. The firefighter doing CPR is doused, the airway is now obstructed, and your perfect code is spinning out of control.
