I think there are nine hurdles in the divers’ Grand National and, of these, there
are two that may or may not prove to be insurmountable obstacles, anaesthesia
by inert gases and the effects of pres...
Effect of brief, repeated hyperbaric exposures on susceptibility to nitrogen narcosis
nitrogen narcosis hyperbaric chamber adaptation
2009/3/30
We investigated the effect of brief, repetitive exposures to 5.5 ATA (148 fsw) in a hyperbaric chamber on adaptation to nitrogen narcosis. A standing-steadiness task, which measures body sway, was adm...
Relationship between the event-related brain potential P300 and inert gas narcosis
narcosis cognitive inert gas narcosis
2009/3/28
It is known that inert gas narcosis slows both reaction time (RT) and the event-related brain potential P300 in a correlated and dose-dependent manner. On the assumption that P300 reflects the time to...
Nitrogen narcosis and ethyl alcohol increase the gain of the vestibular ocular reflex
helium heliox nitrogen hyperbaric air alcohol narcosis dive
2009/3/26
The effects of air, helium-oxygen (6.4 ATA), and ethyl alcohol (40% by volume at a dose of 1.5 ml/kg body weight) were examined on the gain, number of beats, and phase lag of the vestibular ocular re...
We examined the perception of thermal comfort in six male subjects immersed in water at 28 degrees C (study I) and 15 degrees C (study II), breathing either room air (AIR) or a normoxic mixture cont...
