The oxygen sensor on the device have? The CO2 absorber in the circuit is (tin of pellets)?
information is not enough. Inhalation for 2 hours do to ordinary people. 2 (TWO HOURS)! for example, in the case of the treatment of drug addiction and other .... daily 2 month for 2 hours.
It's in a scientific report read. In any normal installation on classical or semi-closed anesthetic circuit with CO2 absorber. With mask are to be used during lengthy operations that can take hours( and dozens of hours, including under xenon anesthesia). While there is only replace the CO2 sorbent and the fluid traps on the middle parts of the tubing set and replace them.
There is no problem to breathe as long as you want until you get bored, if the composition of the MIXTURE is maintained within the permissible limits, namely:
oxygen in abundance (at least air 21%), xenon is LESS than 71% (because 71 - the minimum anesthetic concentration causing complete blackout), CO2 - trace quantities in the air (because when a few percent of the body reacts frantically wants to breathe, even if the lack of oxygen - that's the way our breathing reflex). Other gases - at the Minimes unless defined otherwise specifically (otherwise the effectiveness of treatment falls), for this reason, the first deep EXHALE, then begin to breathe pure oxygen and breathe it a few minutes and then, preferably on the exhale and holding the breath change oxygen to clean and add xenon.
Then the maximum efficiency.
You described like three options:
1) in a mixture of real-time oxygen is not added in a proper amount (must be a small flow of gas all the time, or just a large - impulse usually hands performing the procedure)
2) from a mixture of CO2 is not removed or is not properly removed. It is highly likely that (time dentist)
is here any such thing com/watch?v=psiNc3A7CnM">

if you carefully watch the video - where the sorbent poured in maaaaaaany the bottle doesn't flow type. This is nonsense. It will be something to absorb a little bit, this circuit is suitable for 3-5 minutes inhalation before a dental session but not normal therapy!
It turns out that there is no absorption of CO2 and after some time due to its excess in the circuit, there is a feeling not a grasp of air (the desire to breathe - a reflex result of excess CO2)
here is a typical circuit for operating
http://www.intersurgical.ru/products/ci ... -soda-lime
the photo shows that the Bank - flow, and significant amount of of square. In addition, typically, the circuit - reversing valve.
3) well, there is a third option - an excess of xenon and oxygen deprivation, the desire to breathe deeply - the result of hypoxic hypoxia (
is the correct term to indicate the source of hypoxia - lack of oxygen)
Do the same Pipchenko xenon is not just "kaboom" and under his careful supervision - he barely adds and asks your reaction at the appointed sign - this is usually such as to raise the arm and twist your palm is enough xenon, all individual threshold of sensitivity. T/e/ there is no need to pour gas to "everything swam before my eyes"....
In this version as You currently have (if you breathe in a large amount of gas for a few minutes) out throwing money and their office in a literal sense - to the wind.....
Gas is a lot less to spend or therapy for the same amount of gas a few times or simply much longer.
If I'm right and the fact that it's a camera "stacks" with a very funny cartridge for absorbing CO2, then in principle it is possible to "cure" by placing between the mask and the tube (for example together with or instead of bactericidal cartridge) jar of standard nozzles with soda lime.
The nozzles can be recovered from spent cartridges. Soda lime is cheap and should be in the office to be time they service your machine, and the Bank suitable household plastic 0.4-0.6 liters with a tight lid. In the bottom and lid to make holes for bonding of pipes or parts of a disassembled filter from the back side to attach the net a La a nylon stocking (to granules and dust of lime do not slide in the tube).
Ffffce..... This will fix this drawback. Well, if allowed to do so.<
