| Query on 'Off Effect'
G'Day,
From 'Oxygen and the diver: Kenneth Donald, pg 67' there is mentioned an 'Off Effect'.
Namely "The 'Off Effect' on returning to air breathing after exposure to toxic tensions of carbon dioxide is well known. there is a sudden exacerbation of symptoms often associated with headache, nausea and vomiting." "In one or two cases it appeared that convulsions were precipitated by reverting to air breathing"
Whilst, this appears to support either a good FFM or a BOV (& gag strap) that you can vomit into (& clear) and/or at least retain the ability to breathe from whilst convulsing post getting off the loop after/during a CO2 hit.
It doesn't appear to delve further into the subject with regard to air breathing, apart from that the effect is well known, does anyone know any further references/reading on the subject of the 'Off Effect'?
Have any studies been done, comparing going onto Trimix/Heliox as opposed to Air after a Co2 hit?
Regards
