Circus1031,
The jury is actually very accurate in their comments. A flow rate of 8 liters/minute using a properly functioning non-rebreathing oxygen mask will work in many cases at the lower cluster headache pain levels... if you start the oxygen as soon as you feel the onset symptoms of an approaching attack...
Once the pain has reached the point where the eye and nose start to gush, you'll likely be at a Kip-6 to Kip-7 pain level. At that point, the odds are against you and an abort with 8 liters/minute is unlikely or it could take a long time.
If the pain is such that you start the cluster two-step dance or you're head banging on the carpet or wall, an oxygen flow rate of 8 liters/minute is useless. It may even prolong your attack due to CO2 buildup because of insufficient lung ventilation when constrained by the low oxygen flow rate and non-rebreathing mask. The increased physical activity associated with the higher cluster headache pain levels requires much higher lung ventilation volumes than 8 liters/minute to clear CO2. 25 liters/minute is not unreasonable.
As a suggestion, call you home oxygen provider and ask for a regulator good for a flow rate of 25 liters/minute and a properly configured non-rebreathing oxygen mask with all three check valves (2 exhaust and 1 inlet)...
Tell them you suffer from cluster headaches NOT COPD and that you need the higher oxygen flow rates as an abortive for cluster headaches and not as supplemental oxygen for COPD with a nose cannula.I your home oxygen supplier balks at 25 liters/minute, ask for a regulator good for 15 liters/minute.
If that fails, call the physician who prescribed your oxygen therapy and ask what he or she indicated in the Rx... If it was written for an oxygen flow rate 15 liters/minute with a non-rebreathing oxygen mask, call your home oxygen provider and ask for the name of the physicians in their organization who changed your doctors prescription. If there was no physician, advise them that changing your doctor's prescription amounts to practicing medicine without a license and that's a Federal offense.
If your physician wrote the Rx for 8 liters/minute, plead the same case for a flow rate of 25 liters/minute and a fallback of 15 liters/minute.
You may need to send your physician the following standards of care for the proper treatment of your cluster headaches.

It's also a good idea to read the post on "How To" obtain a proper prescription for oxygen therapy at the following link:

It addresses the problem you're having to a "T" and contains some downloads at the end of the post that you can print and send or take with you to your physician when you ask for the higher flow rates.
Finally, most of us who use the higher oxygen flow rates above 25 liters/minute have purchased our own 0 to 60 liter/minute regulators and love them or we use a demand valve with one of these regulators and love it too.
Please feel free to PM me and I'll be happy to send you the contact info and ordering specifications as they build these regulators to order.
Take care,
