Nice, quick note, lifting the legs when someone is out isn't going to positively influence how quickly bloodflow returns to the brain. It's an old practice but choking stops fresh blood from going into the brain and oxygenated blood from leaving the brain. Lifting the legs actually slows the exit of old blood and can actually close the airway prolonging reduced oxygen. Really the best thing to do is protect the airway and if they look like they will throw up (which can happen) rolling them into the recovery position (side lying) allows vomit to leave without blocking the airway.

Thank you for the tips, but what do you mean by protecting the airways? Can you explain better? Thank you
