Reactive Oxygen Species, Mitochondria, and Endothelial Cell Death during In Vitro Simulated Dives
SCUBA DIVING OXIDATIVE STRESS REACTIVE OXYGEN SPECIES MITOCHONDRIAL MEMBRANE POTENTIAL CELL DEATH ENDOTHELIAL DYSFUNCTION
2017/4/19
Purpose: Excessive reactive oxygen species (ROS) is considered a consequence of hyperoxia and a major contributor to diving-derived vascular endothelial damage and decompression sickness. The aims of ...

Hyperbaric arthralgia during helium-oxygen dives from 100 to 850 fsw.
Decompression sickness during saturation dives
saturation decompression neurological chamber
2009/7/20
Available Navy saturation diving data were analyzed for an evaluation of the therapeutic adequacy of decompression sickness treatment procedures and for delineation of precipitant factors in the etiol...
Joint crepitation after chamber air dives to 188 fsw. Undersea Biomed. Res. 4(1):89-94.-Joint crepitation was observed in all subjects (8) who were decompressed from 188 fsw (gauge) dry chamber air di...
Hematologic changes after daily asymptomatic dives
human Hematologic Erythrocyte Blood Coagulation
2009/7/20
Hematologic alterations after daily exposure to compression/decompression in open water are described. A standard dive to 100 fsw for 25 min was employed. Erythrocytes decreased postdive, reaching an ...
Nature and treatment of decompression sickness occurring after deep excursion dives
human case report decompression sickness saturation excursion
2009/7/17
During Predictive Studies IV (PS IV), the fourth in a series of collaborative undersea investigations, plans were made for excursion compressions to 1200 and 1600 feet of sea water (fsw) from saturati...
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...
EEG and evoked potential changes during gas- and liquid-breathing dives to 1000 msw
compression high pressure nervous syndrome neurological symptoms liquid breathing oxygenated fluorocarbon liquid
2009/7/15
To test the hypothesis that compression in helium gas and compression without gas (hydrostatic compression) both produce the same neurological symptoms of high pressure nervous syndrome (HPNS), groups...
Central nervous system reactions during heliox and trimix dives to 51 ATA, DEEP EX 81
nitrogen human heliox trimix
2009/7/15
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...
Circulatory functions during immersion and breath-hold dives in humans
cardiac output dives humans
2009/7/15
An unusual circulatory state exists in humans immersed in water at or near 35 degrees C. This circulatory state is characterized by a persistent and elevated stroke index (SI) but heart rate (HR) chan...
Respiratory function during simulated wet dives
human Respiratory exercise Work of Breathing
2009/7/15
This presentation focuses on the effects of static lung loading (SLL) on diver performance. It is noted that SLL may arise from depth differences between the diver's chest and his breathing gear. Stud...
Seventy-six men and 7 women performed a 2nd dive in a pressure chamber under dry conditions after intervals at the surface of 10, 30, 90, or 120 min. Of these, 35 persons performed a 3rd dive after an...
Effects of He-O2 breathing during experimental decompression sickness following air dives
decompression sickness pulmonary cardiac output heliox treatment air embolism animal dog
2009/7/14
The effects of ventilation with He-O2 during decompression sickness (DCS) and venous air embolism were studied. Fifteen anesthetized dogs were mechanically ventilated and subjected to repeated air div...
Intraosseous pressure changes during simulated dives: fact or transducer artifact?
Intraosseous pressure bone animal rabbit
2009/7/14
Anesthetized rabbits were placed in a compression chamber and the intraosseous pressure (IOP) in one femur was recorded during simulated dives to a depth of 20 m. No change in IOP was observed during ...
