I see people posting that they have trouble getting scripts or prescriptions for oxygen so I did a little look around to see what is available.
I sense that this problem may come from doctors not knowing how to get hold of oxygen set ups outside of their own surgery environment.
I have inserted some pics in this post but they may not present on the site due to my inability to post pics but if you go to the link provided you can type in the part #s and have a look.

Here in Western Australia all that is needed to get the equipment is to set up an account with BOC gasses, easily done by going to one of their outlets and simply starting one up.
You can either buy the gear yourself or for the short term if you are episodic you can hire for a monthly fee a regulator & flow meter that fits the small C size bottle, you will have to pay for the oxygen and an annual rent on the cylinder you then only need the non re-breather mask that you may be able to con from ER if you know someone there.
The beauty of the rental gear is that you don’t have the initial outlay cost and when you go out of cycle you just return the gear, when you return the bottle you should get a credit on the annual rental if you have only had it for a short time.
Here’s the part # for the portable hire gear. It is much like the oxy viva gear you see the paramedics carrying in an ambulance.
Order Code 401KITC Portable regulator & flow meter to fit C size bottle

My set up is a normal welders oxygen regulator attached to a D size medical oxygen bottle, good for home and reasonably portable with this flow meter attached.
You need to get a fitting with a barbed end to attach to the bottom of the flow meter to which you attach the tube of the non re-breather mask, I got my mask from the ER last time I was hit, they are normally throw away after use as the wont use them on anyone else for health reasons.
Flow meter part # 105215 0 to 15 Litres / Min
This is the normal D & E size bottle regulator

Non re-breather mask: The normal mask doesn’t have the bag attached and the non return valves in the side of the mask.


This is my set up kept in the spare room ready to go; I use the D size bottle and a normal welder’s regulator. The other regulator I have shown is the recommended oxygen one; I don’t think there should be much difference.

Hope this helps out.
Kind Regards
