My walking pace quickened.
Over the next few minutes my pager would go off three more times, all stabbing victims who, I learned later, had all been at a house party when two cars full of lunatics arrived with various sharp stabby things and a thirst for random violence.
I ran from room to room to room trying to determine who was the worst injured. Two of them appeared to be completely fine, and two looked to be slightly less fine though still seriously injured. And there was one whose wound looked like it should have been actively killing him, though in reality he looked as though he could have walked home.
That, of course, was Michael.
His rather scary-looking injury was a single stab wound just to the left of his sternum. Though it was a potentially dangerous (ie lethal) area, his heart rate was 70, his blood pressure was 120/65, and he looked calmer than I (though the fact that I kept running back and forth among four other victims may have riled me slightly). He kept asking when I was going to patch him up and send him home. I did a quick ultrasound which showed a bit of fluid around his heart, and a CT scan done a few minutes later (as I was putting a chest tube into Victim #3) confirmed a hemopericardium (blood around his heart).
Except that I still had 4 other victims to tend to. Fortunately #1 and #2 just needed a few stitches and #3 and #4 both needed only chest tubes. Nothing else life threatening.
