There is some slight leakage around my plastic tubing with tests also but the bag still inflates pretty well--You can test it with the oximeter on your finger like I did--Get the oxygen out of your lungs while inflating the bag,then pull it down to your neck and do 5 deep breaths--See if your oxygen dropped from 98 to 45 like mine(oximeter reading lags by a few seconds)I did some test today but something seems wrong. I used a elastic cord as explained in PPH, adjusted very tighly to a glass vase. The plastic bag needs like 1 minute to inflate even at 25 lit/min and it is just 45x45 cm. There is no apparent leakage but the bag never fully inflate. The upper corners are very loose and just can feel some gas exiting around the hose. It gets better if i manually press the bag around the hose but the bag is never at tension. At least there is no risk of bag exploding or open in the upper side but I am not sure if it is inflated enough. I will try with a sport elastis band to test if there is a significant difference. Maybe the bag is functioning well and is just the atmospheric pression doing its work, but i wanted to ask how tension the bag must be.
I'm using a maxdog regulator but the max is 15 lpm not 20 lpm, but my tank is 3000 liters so I'm sure that will be sufficient to ctb---Greenberg disagreed with much of FromGermany's statementsN means nembutal. Many like myself come to this forum because had heard of Sarco or exit bag, but nembutal is a best method and maybe you can get it. Make sure you read about it before buying inert gas equipment.
Supossedly you can change a regulator of one gas for another if you calculate the flow, but @FromGermany do some warning about cheap equipment and reconversion of oxigen regulators to nitrogen use (MaxDog) might not be adecuated because of regularity of flow and max PSI suportted. I dont know is he is right, but i wouldnt change regulators just in case. I bought a argon tank and an argon flowmeter-regulator (it doesnt matter if is argon or nitrogen) from a local gas shop. Sadly the regulator dont have a trademark or something so I guess is a cheap chinese one. More reason to do a full test with to see everything is ok (nor fuges, bag is ok, sufficient gas, adecuate flow, cord doesnt get loose, etc). I recommend as fromgermany did to use a head mannequin or something similar to you neck width (a vase, a lamp, etc).
Relating to the energy of the convulsions, according to multiples accounts attendants just need to hold their hands. In this 4-case report is described in detail: https://www.jstor.org/stable/20696752. I strongly recomend read it. Search it in Sci hub. They seems sincopal myoclonus because the brain is turning off, not tonic clonic seizures (some type of epileptic seizure) as I initially believed. Nevertheless, as you can see in the fourth case, it can occur unexpected results so better assume the worst case scenario, especially if you have epilepsy. In either case, just a knot holding your wrists should be enough. Neck movements seems limited, but the same what can be said about hitting your head against the bed can be said about the headpiece of a seat. Remove it if you can. Also add weigh in the chair base if it is too light so it dont fall.
In the mentioned study, they used mask and i assume they were in bed because of the model photographs. This study showed why you should NEVER USE A MASK. Using a bag plus a non-rebreather mask maybe it is not a bad idea as a double safety method if the bag get broken but I had read anything about it. They just assume that wont happen.
Respect the flow. USE AT LEAST 20 L/MIN. The article mentioned says you need minimun 25 l/min to a rapid lost of conscious and death. At least for 40 min, 1 hour is better. Do the math and you will need at least 1 m3 or 1000 litres.
