Sean, there is so much in your thread ...

Yes, I agree, you should discuss it with your doctor, BUT, there are a lot of doctors that do not know about the advantages of pure oxygen, and you have to go to another doctor, or even go behind their backs.

Rule of thumb is, if your bag is 1/2 to 3/4's full during use, you are at the correct LPM for you. If your bag is always full, your regulator is too high and an overflow of o2 will fill your mask, causing the o2 to leak out the sides without you breathing it, thus you are basically wasting it. This is very important if you are "self" pay. If your bag is collapsed, you need to increase flow etc etc.
As far as not needing to go higher than the 15LPM, or even not as high, it is totally dependent on the user. There are some, on this site, that are able to abort, successfully, at only 8LPM, and that is GREAT!
BUT, those are in the minority. Most need AT LEAST 15LPM. Many need to go higher. Not saying that these people cannot abort at 15LPM, but it can be done SO much quicker, at a higher LPM.
There are also those that CANNOT abort at 15, but can at the higher flow rate.
I am not sure about all the reasons (I am NOT a doctor or scientist), but I feel it has to do with several factors:
Lung size
Lung expansion capability
Lung condition
PH levels
Amount of CO
2 in the system, and being produced
Strength and elasticity of vasal bodies
And probably many other conditions, too.
We have found that hyperventilating pure oxygen has amazing abortive capabilities. It forces you to stop producing CO
2, which is a major vasal dilator. By having low to no CO
2 and an excess of O
2 you have tremendous vasal constriction, thus cluster headache aborting. We have shown that in many cases, myself for instance, we have cut the abort time from around 20 minutes, to less than 7 minutes, some even at 4 minutes! THAT is a AMAZING improvement! The quicker the abort, the easier it is to live our lives in a normal mode.
I agree with the statement that if your bag stays full, the flow rate is too high. BUT, if you are breathing properly, there is NO WAY that the bag can remain full!
By breathing in, and then holding it, and waiting for the bag to fill again, you are not slowing the production of CO
2. You need to breath deep, and fast, in order to do that, and that cannot be done with 15LPM.

Yes, this is true. If you regularly clean your equipment, you will prevent this from happening. This is one of the reasons that many of us have given up using the bubbler. It is a lot easier to stop for a second, and grab a swig or two of water.
Sean C wrote on Feb 9th, 2009 at 9:39pm:My forth and last comment is that 100% o2 inhaled 100% over long extended periods has not been proven harmless.
This is flat out wrong. The military has had its fighter pilots breathing 100% oxygen for two or more hours, straight, while they fly their missions. They have been doing this for 60 or more years. The military would NOT do this, if it was dangerous. They have studied it MANY times, and found no ill effects.
Remember, I am NOT a doctor or scientist, but this is the result of my reading, and personal experience.
