Hello everyone. My name is Molly and this is my first post although I have been lurking for a couple weeks. My boyfriend of two years suffers from clusters. He has been in remission since we met but they are back and they are ramping up. This is my first foray into the messed up world of clusters. I am trying to learn as much as I can to do whatever I can to try to help but am really green to this.
He has tried many of the treatments explained here and the only thing that has provided relief is O2.
Here is my question-the neuroligist has refillied the O2 script (I think the flow is like-18). The 02 company charges an outrageous amount to rent the regulators. He owns a regulator for the big tank so the O2 is affordable but he really needs a small tank for his car and his work truck. He is living in fear that he is going to have an episode while the O2 is not at arms length. How do I go about buying a regulator for the small tank? Are the regulators all the same or do the differ between tanks? Can you just buy a regulator and how do you control the flow. What is the size of the little tanks for the car. Sorry-I am sure I could figure this all out between the neuroligist and the O2 company but you all seem to be the experts so I thought I would try here first.
Although you don't know it you have already been a wealth of information to me. I am glad I found this forum and thank you all for your invaluable advice.

Some, here, have bought inexpensive regulators off of ebay.

Thanks, the oxygen terms explained helped a lot.

Start price is $1.00!
