The major objective of this study was to demonstrate the advantages of transforming raw scores to ipsative form (deviation scores calculated around each subject's mean), particularly in diver research...
Air and nitrox saturation decompression:a report of 4 schedules and 77 subjects
decompression saturation report
2009/7/15
Seventy-seven subjects were decompressed from air or nitrogen-oxygen (nitrox) saturation exposures at 18.3 to 40.2 meters sea water (msw) [60 to 132 feet sea water (fsw)] using four different decompre...
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...
CO2 retention during hyperbaric exercise while breathing 40/60 nitrox
exercise CO2 carbon dioxide air nitrox
2009/6/9
We evaluated CO2 retention in 24 Navy construction divers breathing air at 1 atm abs (101.3 kPa) and 40% O2 (40/60) nitrox at 4 atm abs (Po2 of 162.1 kPa) inside a pressure chamber. The divers sat imm...
Measurement of fatigue following 18 msw dry chamber dives breathing air or enriched air nitrox
Analysis of Variance air Atmosphere Exposure Chambers Atmospheric Pressure Attention Decompression
2009/6/4
Many divers report less fatigue following diving breathing oxygen rich N2-O2 mixtures compared with breathing air. In this double blinded, randomized controlled study 11 divers breathed either air or ...
BSAC gives the OK to nitrox
DIVING nitrox training
2009/5/26
The possible use of nitrox (oxygen-enriched air) for
sport diving was first examined by a BS-AC working group
set up at the end of 1991. Having examined the advantages
and disadvantages in some det...
“Nitrox” is an easy word to use for the range of
oxy-nitrogen mixtures but there are several other terms also
in use. For those mixtures in which the oxygen content is
greater than 21%, “Enriched A...
Squeezed side by side between walls of silt, my
buddy and I excavate among the collapsed timbers of the
200-year-old brigantine. Our airlift, rising vertically
between us, spills plumes of sediment...
