SURGEON Daren Forward was acting as major trauma consultant when Jason arrived at the QMC following his accident.
He said: "I was the first person to see him as he came through the door, and coordinated his immediate treatment.
"He had chest and head injuries, a fractured shoulder blade, neck, and ribs, and a major blood vessel to his right arm had been torn near his collarbone.
"He had collapsed lungs on both sides, and a bleed on the brain. Most of his injuries were concentrated in the head and neck region, and were consistent with leaving his motorbike at speed and hitting something.
"At that stage, his head and chest injuries, and the bleeding, meant Jason had three different reasons to die.
"We got him incubated, put tubes down his throat, and put chest drains in each side to reduce the pressure so he could be ventilated properly.
"With his arm, the focus was keeping him alive and then trying to identify why it was bleeding, stop it, and restore circulation. He also had a number of scans to the head, chest and arm, all within the first 30 minutes of arriving.
"That half-hour window for people on the edge is critical."
Nearly a year on, Mr Forward said it was fantastic to see the extent of Jason's recovery.
He said: "You see people like Jason completely wiped out, dead in the bed, and nearly a year later they are back. It's pretty amazing really.
"People clearly surviving who would have died is a fantastic achievement for everyone in the hospital. It's a huge team effort by the nurses, porters, those in the blood bank, radiographers, and paramedics.
"There's probably hundreds of people involved in that one person's care."
Of the benefits the Major Trauma Centre has brought, he added: "The main impact is that critical patients are now coming to the right place first time, and the quality of care is better and as perfect as it can be.
"With people like Jason, the centre is making that difference in the first 24 hours between them dying and surviving."
