human trimix HPNS high pressure nervous syndrome rapid compression
2009/7/16
In 1978 a series of deep trimix (He-N2-O2) dives was initiated to establish the relationship between a given nitrogen percentage and the rate of compression required to prevent the high pressure nervo...
Effect of compression rate on use of trimix to ameliorate HPNS in man to 686 m (2250 ft)

2009/7/16
Previous man dives, in a series designed to evaluate the physiological effects of helium, nitrogen, and oxygen (trimix), investigated the comparative effects of 5 percent vs. 10 percent nitrogen with ...
Central nervous system reactions during heliox and trimix dives to 31 ATA
human trimix heliox Central nervous system
2009/7/16
Two groups of divers were compressed to 300 msw (984 fsw) with heliox (n = 3) and trimix (n = 3). Neuropsychological/neurological testing was performed repeatedly during the compression and on reachin...

Two groups of divers were compressed to 500 msw with heliox (n = 3) and trimix (n = 3). They were followed with repeated neuropsychological and neurological tests during compression, at stable interme...
Soleus H reflex studies in humans at 40-70 bar in helium-oxygen-nitrogen (trimix)
decompression human trimix Hoffmann reflex
2009/7/15
Excitability of the Hoffmann (H) reflex was studied in 6 subjects at pressures of 40 to 70 bar during two trimix exposures (10percent N2, 0.5 bar O2, the remainder He; Atlantis II and III simulated di...
Two groups of divers (Group A and B) were compressed to 500 msw with trimix (n = 3) and heliox (n = 3). After 4 d at saturation depth Group A had a gas change to heliox. Both groups were followed with...
Rat brain catecholamine release at 1,10,20,and 100 ATA heliox,nitrox,and trimix
helium heliox nitrogen narcosis animal rat nitrox chamber catecholamine
2009/7/10
The pattern of neurotransmitter release in the rat caudate and hypothalamus was studied following exposure to pressure in combination with various gas mixtures. The caudate was selected for its contro...
An investigation of cardiovascular reflexes during a trimix saturation dive to 450 msw (GUSI 17)
human baroreflex cardiovascular saturation trimix
2009/7/8
The study examines the hypothesis that the carotid sinus heart rate baroreflex responses are changed in human subjects on exposure to 450 msw. Baroreceptor reflex changes in heart rate (expressed as m...
