- Young lad breathing too fast
- Mildly aggressive or attention seeking behaviour
- Tingling in hands and fingers (also in feet but not in this case)
- Feeling of being strangled
- Pain in chest
- If there is something causing stress, remove it from the equation or take the person away from it, or, as in this case, get bystanders to walk away.
- Be firm, polite, but firm and reassure them.
- Get the casualty to... what was it the Prime Minister said? "Calm down Dear!"
- Lower the oxygen level and raise the CO2. How? I hear you say, well there is always the good old paper bag trick, but I'm a bit more high-tech than that...
So what was this magic gas that did such a fine job of restoring the lads health? Nothing much, no seriously, nothing. I didn't connect the mask to the gas cylinder. It was an oxygen cylinder anyway. He was hyperventilating, so the last thing I wanted to do was give him more oxygen, but he didn't know that. All he was doing was breathing in and out of a mask with a bit of tube stuck on it. But the nice medic made him better with this magic gas. Yeah, I'm nice like that!
Now, after my little lesson, everyone of you will know what to do if you find a mate hyperventilating, so I can relax and go watch telly.
Oh, one last thing, here's a new word for you...
Go look it up ;o)
