ABCDE

Amazing how much has changed in the last 15 years since I last took first aid. Now it's not ABC but ABCDE. Airway, Breathing, Circulation, Deadly bleed, and Environment.

The "high" point of the first day was learning how to use a defibrillator. Bring on the cardiac arrest patients. Well... not really. The new way of doing CPR is exhausting after a couple of minutes, so you really need another person to trade off with. The new rule is 30:2 - 30 pumps and 2 breaths.

Also learned that the heart can beat on without the brain. I suppose I already knew that (as I blush).
