First Aid procedures change intermittently, which our trainer on my refresher course last night explained is a mixture of planned reviews and new evidence coming to light. We were told that the new advice is to call for help at the scene before checking a casulty's airway.
I was reminded by May's post today that my first instinct on being told this was to yell "Heyulp! Heyulp!" like Penelope Pitstop.
