I phoned Andy's mother and step-father to offer my sympathies that they are going through this.
Apparently he has made a minor improvement since yesterday and now takes 5 breaths per minute on his own, and has a vague awareness (kind of semi-conscious) now they have lowered his morphine a bit, but still pretty much relying on ventilation and they have made a hole in his neck to put this tube down to help him breathe (can't think of the name for it, begins with trach). They still don't know the outcome, he could go either way as he worsens and then improves, and then worsens etc, and his leg isn't great, but he at least has been making an effort to breathe.
The trouble is, his lungs are already scarred from the last time he had pneumonia so even though they've drained off the fluid, it's still difficult for him.
I let them know I was thinking of them. There's nothing else I can do, and I don't think it works going round there to help Andy.
