You are dispatched to a “patient unconscious” and arrive on scene to find an obese man in his mid-50s, unresponsive and apneic. As his wife is describing his extensive cardiac history, the man goes into cardiac arrest and you initiate resuscitation. He is asystolic, so you immediately turn to drug therapy, only he has no veins to speak of. Your only option for drug therapy is through the endotracheal tube, which is also the best means of securing his airway, so you set up your equipment, have the suction unit close by, and position yourself for intubation. It’s not going to be easy.
