Title: Too much oxygen? Post by candid on Jan 19th, 2010 at 4:57am
Hi
I've been having a really tough time for the last 2 and a half weeks. I'm a chronic and my patern became pretty consistent but all of a sudden im terrified. The oxygen hasnt been workig nearly as well. I can go through an entire E cylinder and the pain hasnt receeded. Even when I'm on the oxygen the pain isnt receeding like it used to. The oxygen is still helping but only in the way that its keeping the pain somewhat tolerable but even afer sitting on the o2 for 45 minutes - 5 mins after i get off tge pain ramps right up again. Anyway my question is if its possible to suck down too much oxygen and suffer adverse side effects. I went through 5 E cylinders yesterday and 7 the 2 days before that. What is too much? How do I know if im overdoing it? My doctor has told me I need all the help I can get and told me to use zomig on a daily basis. but with o2 not working as effectively im so scared the pain will comeback tenfold- magnified by the zomig and then i have nothing to treat that pain with. I've been using oxygen to abort my clusters for over 3 years and it was amazingly effective until 2 and a half weeks ago when i started to taper from my beta blocker-inderal. For the last 2 weeks its been pain to the point of imprisonment. I'm sorry for bitching im just reallly struggling |

Hang in there bud. I know the the pros on here will have suggestions on this. BTW, what is your flow rate?
I'm wishing you PF days ASAP! |

Thanks chad,
I use 25/lpm or 15/lpm |

Sorry that you are in such a bad way Candid :(
Have you read the o2 link? There is updated info available. Do you have a specialist in Toronto? If not send me a PM and I will pass on my MD who is a Headache Specialist as well as a Headache Researcher. He accepts new patients and is very well versed in CH. Hope you find some relief soon :) Iddy |

that's very interesting..i'm using an o2ptimask..
I guess i gotta get me some supplements. Still...is there something that can happen regarding the clusters or general health if you're sucking down 6 E's a day? |

Candid,
The average abort at a flow rate of 25 liters/minute should take 8 to 10 minutes and consume 200 to 250 liters if you're breathing properly and not having complications like a low pH. As the average E-size oxygen cylinder holds 708 liters... you get a max of 3 aborts... If on the other hand, you're not breathing properly, the pain is in the Kip-7 to Kip-9 range, and your pH is low, the aborts can take as long as 25 to to 35 minutes and aborts taking up to as much as 50 minutes are not uncommon as you've already figured out. At that rate, it's easy to burn through an E-size cylinder in one abort. See the following link: START PRINTPAGEMultimedia File Viewing and Clickable Links are available for Registered Members only!! You need to ![]() ![]() It shows a fully charged E-size cylinder will deliver 35 minutes of oxygen at a flow rate of 25 liters/minute. If we factor out the low pH condition there's a logical reason for the longer abort time when not breathing properly. When the tidal volume (the volume of oxygen inhaled with each breath) is on the order of 4.0 to 4.5 liters (a very deep breath made possible with forced exhalation... i.e., squeeze till you wheeze,) we'll have a residual volume of 1.5 to 2.0 liters remaining in our lungs. This is based on the average adult male having a total lung capacity of 6.0 liters. In this case, a tidal volume of 4.0 to 4.5 liters will ventilate the lungs to the maximum extent possible and wash out the most of the CO2. If on the other hand, the tidal volume too low, say on the order of 2.0 to 2.5 liters on the inhale cycle, we're breathing too shallow. This leaves a larger volume of residual breath (3.5 to 4.0 liters) left in the lungs. As the residual breath contains the highest CO2 concentration, we've set up a tug-of-war between elevated oxygen concentrations and elevated CO2 concentrations. An elevated oxygen concentration supports vasoconstriction that aborts the cluster headache attack, and an elevated CO2 concentration supports vasodilation that prolongs the attack. That makes oxygen your friend and CO2 your enemy... Hope this helps... Take care, V/R, Batch |

thanks batch, a lot of interesting info..
i brought up the ph thing with my doctor but he didnt seem to think i was talking about anything. So I guess I gotta get supplements and hyperventilate.. whats so frustrating is that it worked so well for so long and then it decides to stop working...God definitely knows how to test the limits of ones sanity. Thanks for putting my mind at ease about sucking too much oxygen...i guess now my worry is paying for all these cylinders. Thanks again, feel free to add i love the info |

Candid,
Just to toss in another POV - My HA specialist emphasized, and writes on the O2 prescription: "Breathe normally for 15-20 minutes, seated, facing floor". He demo'd the position, sitting, bent over, facing the floor. Supposed to help the blood flow & O2 reach the head faster. "Seated" can be a challenge if it's a hard hit and you're "dancing". I see others "huff" the O2, and I suspect their attacks are worse than mine. 15 LPM in the facing floor position has been working for me. Usually abort in 6 minutes, but always doing minimum 15 minutes O2 to ensure. 12 LPM worked before, but 15 seems to be necessary for me this cycle. Your mileage may vary. Just sharing 2 cents here, FWIW. Hoping you can knock the Beast down... Fox |

First time I've ever heard the "facing floor" thing. Sounds kind of "wives' tale"-ish to me.

The "seated facing floor" thing just kind of came to me naturally. Although I add my own twist of rocking back and forth ;)

This was a recommendation from New England Center for Headache. Take it FWIW, not straight to the bank. Whatever works best for each of us, doesn't work for all of us. Fox |
