06/13/2013: "First aid - CAB (circulation, airway, breathing)"
You've tourniqueted the bleed or splinted the fracture, and checked the victim's pulse and blood pressure. You also need to make sure he's breathing, especially if he's unconscious.
Note: Several months after we held this seminar, the American Heart Association revised the order in which to do these steps from ABC to CAB. The rest of the information in the video still applies. (Note that the speaker references the upcoming change; the AHA just hadn't made it yet.)
Part 1: introduction, vital areas
Part 2: bleeding
