I have very recently been given the above oxygen flask for amblutory use. I was thrilled to be prescribed it as it's so much lighter than the usual tanks and lasts a lot longer as instead of a continuous flow of oxygen it just gives a spurt of it on the inhaled breath. The down side of it is the HUGE tank of oxygen, however with the movement of furniture I have been able to make space for it.
However I'm having lots of teething problems with it, the first flask I was given lasted only two hours and not the five as stated, the providers very kindly bought me out a new flask and once again showed me how to fill it and told me that the oxygen would evaporate when not used. So used it to take my dog for a walk for an hour, noticed it was giving me the spurt on the exhale breath and didn't work when I used pursed lip breathing. This morning I get all ready for the gym, the flask was empty so I realised it must have evaporated overnight, tried to fill it but no luck despite following the instructions, left it for a while and tried again, no luck yet again. So missed out on the gym and shopping session I had planned.
Anyone else had problems like this ? I guess I will have to get in touch with the providers again but I'm feeling a bit stupid.
Any helpful comments welcomed
