Yes, pure oxygen causes scarring to the lungs.

They had me on ventilation for the first week or two, plus wired to an apnea monitor and kept me warm (womb temperature, LOL). I also had to be fed via nasal tube as I was too young to suck properly. I have got photos where my diaper was up to my chest because I was so tiny, and one of my dad holding me in the palm of his hand - I actually fit in the palm of his hand.

My H was full term (9lbs, 12ozs - ouch!) but he reacted badly to pain medication his mother was given in the labour and so he had breathing trouble as well and was also in neo-natal intensive care.
He has other problems inherited by genes from his dad, which could have passed onto our children, but luckily they are all fine.

I have had 3 miscarriages also so I have a theory that I lost the ones which had inherited H's faulty chromasome. The risk was 50/50 and I gave birth to 4 healthy ones and spontaneously lost 3, so that would work out about right.
Just a theory, though, I may be wrong.

I think it's why I got into medical litigation etc for a career - my background seemed to be an ideal training ground for it. I write health books and H is a computer technician by trade (when he can fit it in with home eding the girls).

It is a relief that our dd's can have their own kids without worrying about the gene, which means our grandkids will be healthy too (unless they get something else wrong with them).

Anyhow, sorry about rabbiting on about nothing. This board is supposed to be about M/D etc and I've just gone off on a tangent!
