Abstract: Increased ambient pressure and oxygen partial pressure (pO2) influence cardiovascular regulation during diving and caisson work. We measured the cardiac output (Q) in subjects who practiced moderate work at a usual diving depth of 30 m. In 23 healthy male...

Hyperbaric Oxygen Therapy (HBOT) Research for Stroke
Dual effect of HBO on cerebral infarction in MCAO rats.
Abstract: Various reports in the literature have shown that hyperbaric oxygen (HBO) reduces cerebral infarction both in animals and humans. After the initial ischemic insult, however, initiating HBO treatment at different intervals has yielded conflicting results. The...
Hyperbaric oxygen therapy for treatment of postischemic stroke in adult rats.
Abstract: The efficacy of hyperbaric oxygen (HBO) therapy for treatment of stroke remains to be validated in the laboratory. We report here that adult rats subjected to occlusion of the middle cerebral artery and subsequently exposed to HBO (3 atm, 2 x 90 min at a...
Neurological accidents caused by repetitive breath-hold dives: two case reports.
Abstract: We report two Japanese male professional breath-hold divers (33 and 39 years of age) who experienced neurological disorders during repetitive dives to over 20 m of seawater. One patient had right homonymous hemianopsia, and the other presented with right...
Hyperbaric oxygen reduces infarct volume in rats by increasing oxygen supply to the ischemic periphery.
Abstract: Hyperbaric oxygen (HBO) increases oxygen supply to anoxic areas. To examine the therapeutic effect of HBO on ischemic stroke, we measured infarct volume as well as cerebral blood flow (CBF), oxygen supply, and lipid peroxidation in the ischemic periphery....
Hyperbaric oxygenation induced tolerance against focal cerebral ischemia in mice is strain dependent.
Abstract: SV129 or C57BL/6 mice were exposed to hyperbaric oxygenation (HBO, 5 days, 1 h every day, 100% O(2) at 3 atm absolute). One day after the 5th HBO session focal cerebral ischemia was induced. In SV129 mice, HBO induced tolerance against permanent focal...
[Severe diving accidents: physiopathology, symptoms, therapy].
Abstract: Decompression injuries are potentially life-threatening incidents, generated by a rapid decline in ambient pressure. Although typically seen in divers, they may be observed in compressed air workers and others exposed to hyperbaric environments....
Hyperbaric oxygen therapy for cerebral palsy: two complications of treatment.
Abstract: There is growing interest in the use of hyperbaric oxygen therapy (HBO(2)) for children with cerebral palsy. Although there is no rigorous evidence to support this management, private hyperbaric centers have been established throughout the United States and...
Hyperbaric oxygen decreases infarct size and behavioral deficit after transient focal cerebral ischemia in rats.
Abstract: Cerebral hypoxia is a major component of immediate and secondary cell damage caused by ischemia. Hyperbaric oxygen (HBO) is a potent means to increase the amount of oxygen dissolved in blood plasma. The effectiveness of HBO in clinical and experimental...
