DIVERS nitrogen elimination aerobic capacity Decompression Sickness chronic training nitrogen oxygen interval training heart rate exercise
2009/6/2
INTRODUCTION: The rate of nitrogen elimination may be an important factor in evaluating the risk of DCS following dives. The present study determined the reproducibility of a method for evaluating nit...
The effect of hyperbaric oxygen on intraocular pressure
Hyperbaric Oxygenation eye intraocular pressure hyperoxia Humans Intraocular Pressure physiology Analysis of Variance
2009/6/2
The effects of hyperoxia on intraocular pressure (IOP) have been studied in experiments on human beings and animals. The changes occurring in IOP in patients during routine HBO2 therapy are unknown. I...

Hyperbaric Oxygenation neurological HYPOTHERMIA ischemia animal gerbil brain hippocampus
2009/6/2
Moderate hypothermia may have a beneficial effect on the neurological outcome. However, ischemic deterioration such as brain swelling during rewarming has been reported as a notable complication after...
Does hydrostatic pressure have an effect on reactive oxygen species in the eel?
reactive oxygen species ROS metabolism hydrostatic pressure migration silvering process animal yellow eel hydroxyl radical superoxyde dismutase catalase malondialdehyde antioxidant enzyme
2009/6/2
Eels are submitted to hydrostatic pressure (HP) during their spawning migration (about 6000 Km). Before migration, they change from the yellow to the silver stage (silvering process). The effects of H...
Effect of heliox, oxygen and air breathing on helium bubbles after heliox diving
DIVING heliox oxygen air helium animal rat DECOMPRESSION bubble decompression sickness
2009/6/2
In helium saturated rat abdominal adipose tissue, helium bubbles were studied at 101.3 kPa during breathing of either heliox(80:20), 100% oxygen or air after decompression from an exposure to heliox a...
The life-saving effect of hyperbaric oxygenation during early-phase severe blunt chest injuries
Hyperbaric Oxygenation Human blunt chest injury trauma cardiorespiratory injury
2009/6/2
The effect of hyperbaric oxygenation (HBO2) on survival during the early phase of severe blunt chest injury (BChI) has not been elucidated. Our aim was to investigate this effect on human victims of B...
Effect of varying deep stop times and shallow stop times on precordial bubbles after dives to 25 msw (82 fsw)
Decompression DECOMPRESSION SICKNESS deep stops DOPPLER Humans
2009/6/2
In our previous research, a deep 5-min stop at 15 msw (50 fsw), in addition to the typical 3-5 min shallow stop, significantly reduced precordial Doppler detectable bubbles (PDDB) and "fast" tissue co...
The effect of body position on inspiratory airflow in divers

2009/6/2
The purpose of this study was to examine the possibility that body position influences inspiratory airflow of submerged subjects. Our previous studies have suggested that for a given (negative) inspir...
There is general agreement that the basic problem in
decompression is gas coming out of solution and forming a
gas phase. However, it is also well known that a
considerable number of bubbles can be...
