Mr. Sandpine, After she crashed she seemed fine, just a little banged up, but she wanted to try to make it to the play pit. When we were almost there she started complaining of some increased pain. by the time we got there she was feeling nausuea and weekness followed with cool clammy skin to the touch (it was during the summer and me and my son were sweating bullets)which progressed to slight shivering. In short, nausea, cool clammy skin, weakness, possible dissorientation, and shivers. I have no doubt she was borderline 2nd stage by the time we got back to the truck, but blankets, fluids, and keeping her calm did the trick. All these symptoms are common after a strong contusion or impact and or broken bones( ask Gregg ). Shock can also be brought on by the stress of the injury. We had a lady at a baseball game take a line drive shot to her face and broke her nose. The impact had flattened it flush against the front side of her cheek. Lot's of blood and trauma. Her husband had gone to the bathroom and concession stand and was absent for all the incident. We had her stabilized and were waiting the EMS when her hubby showed up. He was obviously concerned, and the first thing he said was" Honey, there's so much blood and your nose is underneath our eye!!" At this point she proceeded to go into full blown stage two shock, shaking, sweating, puking and passing out. Anytime any one has an injury and has possible shock you need to get them to the ground to prevent further injury by falling, assure them that they will be okay no matter what the extent of the injury, call 911 in there is any question of their condition, make sure they stay on the ground laying down with the head slightly elevated and ready to turn them on their side (referred to as the recovery position) in case they get sick or vomit so they don't choke on it. Once stabilized do an injury assesment by visually looking at their body for body parts out of place or misalined (Gregg!), cuts, abrasions, etc. First stage shock can quickly proceed to 2nd or 3rd stage if not handled correctly. Such as the husband mentioned above. His dialouge, without meaning to, he was just speaking without thinking, went from stabile o an emergency in less than 10 seconds. Whew, getting my daughter back out to the trailhead was another story. We actually used her bike to transport her to the street you cross to get to the pit. We sat her on the bike, me and my son stood on either side of her bike just behind the handle bars. She grabbed ahold of our Camelbacks and shoulders while we put our handson the stems of our bikes and the other ones on the stem of her bike and rolled her and our bikes out at the same time. The bike actually became the stretcher and we were able to get her to the road quicker than if I had to carry her.
