Help for my wife in General Board Posted March 19, 2015 Yes, excellent advice. Thank you all for your help and suggestions. I currently don't have anyone here in Canberra with the type of knowledge you guys have, so I feel like I'm trying to convince Drs to try alternatives which is difficult. We will see how the next few days go and I'll start chasing up the vitamin D and O2 setup -Â I did obtain an O2 cylinder last year some time, I think with 15L/min regulator, but it was when my wife was getting 10/10 attacks and physically just couldn't get enough O2 into her. Thanks again.
