you has my sympathy for your medical comdition - i know several asthmatics and it sucks to be them
but :
in-line heating is std on ventilators - a simple google - or reading the many ATS threads - would inform you of that
ventilation is often combined with nebulising therapy - the exact type depends on why the patient is ventilated
as for gases - this was my primary irk with your posts in this thread
and this is where you clearly have no clue
your " sugestions " in no particular order :
carbon dioxide - no just fook NO - look up the efects of increased CO2 [ % chart - hint when you get to 10 - its DEAD ]
nitrogen - WTF ???? its an asphysiant - look up the argument for using pure nitrogen as an execution gas [ a idea i support ] - in diving - the entire
point of all the mixes - is to reduce nitrogen intake
oxygen - wow - you actually got something right - but hey 15l / minuite = the std treatment for almost anything [ contradictions include COPD ,
paraquat poisoning ] - more exotic oxygen threapies are availiable
the rest are tech dive gasses - that are [ after nitrox - which is just air with added oxygen - ie EAN 32 = 32% oxygen , EAN 40 = 40% oxygen ]
increasingly techical mixes for advanced DEEP [ > 60m ] dives - and all have < 20% oxygen - because of oxygen toxicity at pressure . the trimix for
80m runs @ just 10% oxygen - which is not enogh for surface use - so you need desent tanks - then switch to bottom gas - then asscent and
decompression mixes
nitrox is a " shallow use " gas [ > 50m ] - thats used to increase bottom time offset nitrogen narcosis - and decrease decompression time
the others replace nitrogen [ a slow gas ] with helium - or really tech stuffs hydrogen which are fast gases
reducing nitrogen = vital to offset nitrogen narcosis - which starts @ 30m on straight air [ typically ]
30m = 4bar pressure - you cannot generate that in an ICU - you need a full spec hyperbaric chamber ]
hospital " hyperbaric treatments " - in a tent - run at just 1.1 bar
so see - thats a primer on your suggested gases - see why i say - you have no clue ?
