you were driving calmly when suddenly a drunk driver hit the back of your car, causing you to hit a tree. Your brother, who is a paramedic, arrived with his team in an ambulance to the scene. Your brother noticed that the lung was punctured by a branch. Your brother put you in a neck brace and an oxygen mask... he's making sure you don't hurt yourself any more or that your vital signs don't drop too much. During this time, the rest of his team prepared a spinal board, a head stabilizer on a spinal board, a blanket and a carrycot. You are waiting for the fire brigade to help get you out of the car (by cutting off the driver's door).
