I've just been given an oxygen cylinder for emergency use by my doctor, mainly because there seems to be a bit of an ambulance shortage in Notts at the moment, made worse by the World Cup, and I was getting edgy about how long I might have to wait for an ambulance.
It's a small cylinder, 300 litres, PD. I was experimenting to make sure I know how to use it in an emergency, and it only goes up to 4l/min, which just barely drives a neb pretty slowly, I reckon it would take 20 - 30 mins to do a whole neb. Obviously in an emergency I need to be able to back-to-back nebs as quickly as possible as well as getting extra O2.
My husband says I should use my neb and mains driven compressor in the normal way and stick the oxygen tubing through one of the holes in the neb mask to give a bit of extra O2, but that doesn't sound very scientific to me! Obviously I'm going to go back to my doc to ask if I need one with a faster flow rate, but I just wondered what type of oxygen cylinders others have got and how they get round this problem.
Obviously, I only would be using it for emergencies and ideally it needs to be transportable for going away etc, so a concentrator (which I know some of you have) would be completely inappropriate.
Hope you can help
