I had a friend watch this recently with a relative and they weren't allowed to say what was in the cocktail (so I wonder if this person could get in trouble for making this public lol). There was also an attending physician who made sure the patient finished the whole thing. The second he stopped, they said he has to keep going and finish it. And they were right next to him to the whole time, inches from his face.
Sounds like this was a failure by the attending paramedic, who was too far or had the slowest reflexes in the world lol.
