I don't think you can get a burst lung from a nitrogen and exit bag? Where did you get this information from?I also was wondering this. But just in case IIRC a high flow rate can cause a burst lung which would be extremely painful
I believe it's the case in mechanical ventilation, so as long as there isn't too much air pressure going directly into your lungs via a mask or something then it's probably fine. Although you wouldn't want the gas to finish too soon so a lower flow would be idealI don't think you can get a burst lung from a nitrogen and exit bag? Where did you get this information from?
Are you sure that higher flow wouldn't cause you to pass out quicker?More flow means more noise and also means the tank will drain faster.
Even if you set the flow on max you wont die any faster. The extra flow will cause the gas to escape from the bag faster. It wont enter your body any faster.
just saw your other post and I'm sorry that you're going through so muchAre you sure that higher flow wouldn't cause you to pass out quicker?
@bennay a higher flow rate would flush out the CO2 that much better.I did some additional research on this, from what I read a flow rate of 15-20 liters is recommended to avoid accumulation of co2 in the bag which would/could cause uncomfortably if too high.
@Itsallover123 thank you for your sentiments. Would the higher flow rate cause unconsciousness sooner?just saw your other post and I'm sorry that you're going through so mucha higher flow would expel gases from the bag quicker but that would waste some nitrogen and might make the supply run out too soon.
@Hyd999 Are you sure?More flow means more noise and also means the tank will drain faster.

I know, but I'm pointing out that's all it's for. It's not going to make you go unconscious any faster.@bennay a higher flow rate would flush out the CO2 that much better.
Should a larger tank be used then with more gas then the flow rate increased?I know, but I'm pointing out that's all it's for. It's not going to make you go unconscious any faster.
More remaining O2, also due to exhaled air, which has at least 14 % O2, makes unconsciousness slower. It's not only about CO2, it's also about removing O2 or at least diluting it. A quick low level of O2 makes one quick unconscious, and low flow rates have been the reason for failure, because people didn't go unconscious so fast they expected and then SI kicked in while they have been conscious. In addition, a low flow rate will not have that positive pressure to avoid that O2 will come in through the neck, where countless but no real specific advices are given to make the bag not too tight or 2-finger-tight or whatsoever. It's vague.
There is a reason, why EEBD systems are working with a very high flow.
The "crunch the bag out of air" is anything but to ensure, there is no O2 remaining in the bag. Of course, there is still some air into it. If you pull the with N2 filled bag down, it's impossible that not again some air will replace some N2. I personal would wait at least 10 more seconds before the first deep breath, so that the flow will reduce the percentage of O2 as most as possible.
CO2 is very important, but the whole system based on the lack of O2, and this includes the speed of unconscious. A higher flow will dilute or remove not only the CO2 from the exhaled air but also the 14 % O2 in the exhaled air.
@Greenberg I'm confusedThe only parameter to consider is the "dead space."
Dead space is the initial volume of air that needs to be displaced to create a wholly nitrogen-saturated environment. In the case of a bag, the dead space is large and would benefit from an initial "rush" of nitrogen to displace the air. In contrast, a small mask such as an oxygen mask would require very little nitrogen to flush out the initial pocket of air within, so a high flow rate is not required.
In terms of an ongoing flow rate during CBT, I believe 15 LPM would be sufficient. Any more, in my opinion, would be a waste and loss to the environment. Please bear in mind that the average person consumes no more than 7.5 liters of air per minute; as such, there is no question that a 15 LPM flow rate would recreate a positive pressure environment.
Having stated the above, I do respect @FromGermany remarks for a 20 LPM flow rate.
As mentioned in my reply: For a bag setup, a higher flow rate would flush out the initial dead space gases quicker. Thereafter, you have the choice to reduce the nitrogen flow. If you have a larger canister (i.e., more than 20 cf) then just leaving it at the higher flow rate is fine.@Greenberg I'm confusedso would a higher flow be best to ensure that the 02 and c02 is flushed out and uncontiousness comes quicker? How can one know if they are leaving enough space open at bottom of bag or too much space? I have a 20 cu canister of nitrogen.
I have an argon regulator that will be set to 25 or 30 this will be sufficient?
@Greenberg no it's between 25 to 30 for my regulator. If I'm understanding correctly you are saying the nitro flow doesn't flush out the CO2 buildup?From recall, I thought the 15 LPM of nitrogen equivalent was 12.5 LPM on an argon flow meter. My recall might be wrong; you may wish to check this. There are calculations presented on my blog.
When you "wear" the bag, it will opens up, thereby drawing air from the environment. Unfortunately, the dead space does not go away.
I am sorry that I am not more helpful. Best, G@Greenberg no it's between 25 to 30 for my regulator. If I'm understanding correctly you are saying the nitro flow doesn't flush out the CO2 buildup?
@FromGermany I am very ill and weak but I'm 56 not 70 and I'm not terminally ill. Final exit have guides that use this method, they have witnessed many people who CTB and are there with the people who use this method. From what I have been told not all are old weak and terminal. Why do you think one has to be old and weak to use this method? (Final exit will be with me on the date I have chosen)If one does not a research at all available sources and cases, studies, this will end up in a permanent brain damage like with the Scuba instruction guide, which is very dangerous and should be removed. The cheap ice mask is sealing nothing and the stage will be anything but airtight, put it in the mask with some piece of butter, what?!, and after unconsciousness the mouthpiece will flop out of the mouth and that's the way, brain damage work.
The nice person who has promoted the exit bag method for months and months as it is the Holy Grail with just an exit bag and gas, at then end, he did not use this method and was going to Swiss. It's one thing to say, how easy and fine everything is, so that other people shall use it, but if one is not ready to use the method for his own, then for me it's a signal to research more, what I have done, and so many things, which have been discussed on this forum as the real thing, can be debunked, because they are too risky.
I really don't understand, why people take this serious matter so easy. Just look at Humphry's insane old two helium tanks instructions video. If you are not over 70 or terminally ill without any power, the chances of failure are 80 % or even more with that "guide" and not because of any probably dilluted Helium.
There are probably many people with brain damage in the care homes, who failed with this method, like this is the case with hanging. It's not like SN or N. In this case you can not say later, oh well, if I did that or that, it would have been worked. It's too late then. This method was designed for people who are almost dead or so old, that there is not so much SI or physical resistance. It's not made for younger people. Younger people have to consider many more things and true knowlegde from all available world wide sources, this is the real thing to have a good chance, that it will work, the only one, if you are not 70+ or terminally ill without any power.
At any age or any health, you're depriving your body of oxygen in which it needs for survival and this method will be fatal unless mistakes are made. Too many think it's just putting together the set up and that's it.If one does not a research at all available sources and cases, studies, this will end up in a permanent brain damage like with the Scuba instruction guide, which is very dangerous and should be removed.

@bennay Final exit guides have never experienced a failure with this method. Using the tried and true nitrogen tank 20 cu and the exit bag. Everything is checked before hand to make sure is operating correctly and there are no leaks. But yet I'm still afraid of failure and I guess that's normal.At any age or any health, you're depriving your body of oxygen in which it needs for survival and this method will be fatal unless mistakes are made. Too many think it's just putting together the set up and that's it.
For starters:
- helium needs to be off the table completely for this method as you can't be sure if purity anymore.
-Do NOT buy cheap scuba gear
-You are not supposed to leave the mouthpiece on the regulator
-The use of butter or lubricant is to help put the regulator in the mask AFTER the mouthpiece is removed.
- be sure you have enough gas to last up to 60 minutes
- Be aware of what could happen during unconsciousness
- I can't stress this enough… do your research!
This method REQUIRES attention to detail, careful planning, and full knowledge of how it works in order to be successful and should not be taken as a "quick & easy" backup method just because the supplies are easy to obtain.
Hey, Im right there with ya. I think that the concern of failure is generally normal with any method.@bennay Final exit guides have never experienced a failure with this method.

@bennay I think @FromGermany is is thinking that an older feeble weak person is less likely to struggle or suffer from SI then a younger stronger person. But I'm not sure of the research behind this.Hey, Im right there with ya. I think that the concern of failure is generally normal with any method.
I think @FromGermany is right, an older/terminally ill person would be less likely to struggle or experience heightened SI. Thats not to say that a younger/healthy person couldn't die from this method at all. Again, research and proper planning is imperative. I, myself, am apart of the younger generation so I feel entitled to say that most in my generation do the simplest of searching, take information at face value and run with it, and in a situation like this, that type of mentality is what will cause failure with severe consequences.@bennay I think @FromGermany is is thinking that an older feeble weak person is less likely to struggle or suffer from SI then a younger stronger person.

@bennay ahhh I see. I am 56 and in very bad health and illnesses. I am weak, but not that weak.I think @FromGermany is right, an older/terminally ill person would be less likely to struggle or experience heightened SI.
