Without wishing to be rude, that is like saying ‘my brother fell off his bike and broke his leg and got completely better after six weeks in a cast. I know your leg has been crushed by a forklift for four hours, but isn’t it basically the same? Why do they have to amputate?’
This isn’t just a glitch. It’s catastrophic carnage.
Archie isn’t just ‘not breathing’ he can’t manage his blood pressure, or his fluid balance. He can’t absorb nutrition. I’m not even sure he’s maintaining his body temperature. He can’t regulate his most basic bodily stability. His brain STEM (the bit that dues this most basic life maintenance) was without oxygen for a considerable period of time, by a method which prevents all blood flow - not an injury which loses blood, or a deterioration which prevents higher functions developing - but a complete loss of blood flow. Parts of his brain are no longer even located in his head, and are necrosing in his back, as it swelled so badly they were forced out of his skull into to his spinal column. Hanging is a method which fairly invisibly and cleanly destroys the most fundamental ability to control the most basic bodily functions.
All brain injuries are not the same. All children are not the same. I am so very sorry it is so, but Archie’s body is just on the very brink of what the most advanced and skilled medical care can do to keep his heart beating. It’s a tight rope he can stay on only with the most intensive and skilled support. It’s very difficult for people to appreciate this, I know. We think of our brain is just the thinking part of us. It’s not. It’s unbelievably and astonishingly complicated beyond most people’s comprehension, as comments like this demonstrate. (Telly has a lot to answer for here!). It’s not in the slightest bit comparable ‘a child in a study’. Twenty years ago, Archie would not have made it into the ambulance.
