How often should my oxygen pipe be changed they left four in sealed bags is that for one week it is still a puzzle how things are done and not long since the supplier changed.
Not on it all the time only when moving about or exercise mostly sitting down not really back onto where I was before yet.
They advised me every couple of weeks others may say different, hope you are getting along ok Val
Why does it need changing forgive me if there is an obvious answer for disposing of an item that is functioning as it should do with associated cost (waste ) that is part of the disposable culture tha twill see us run out of landfill rubbish dumps.
Been on oxygen 6 months and have only changed my cannalas once, that was because I had a cold and they are not easy things to clean. Left it until after the cold had gone though.
Thank you looks as if they have left enough for a couple of months if not longer thought it best to ask if unsure though when doing something a little different it makes you doubt what you are doing.
