He is home with the tube in situ, with a thick pad between the mickey button and his skin, which is there to soak up any fluid that escapes, but has actually served to stop it leaking as it is supporting the tubing that is there making it about the right length. The new tube will be 3 ml shorter than this one and that is about the thickness of the interim padding, so hopefully it will work out. I just re-read this and it doesn't make much sense if you can't see it, but I'm too tired to try and make it make sense.....
In summary, Sam is very happy to be home, back to normal, no orifice is leaking for the first time in living memory, so we're all rapt!
Oh and today was a gr8 day, because the BOC guy came and collected the last O2 cylinder from the house! Sam's been off O2 for 4 months, but they leave 1 tank in the house 'just'n'case' and after 3 months they do another overnight reading to check how things are going....and he came back at having very few desaturations and an overnight saturation average of 96% which is gr8! So it was quite lovely to say goodbye to my friendly BOC guy, knowing that I may only ever see him again in his capacity as a person at the supermarket and not delivery oxygen for Sam.
