Effects of age and magnesium ions on oxygen toxicity in the neonate chicken
hyperbaric age magnesium ions oxygen toxicity animal chicken
2009/7/20
White Leghorn male chicks, 2-6 days and 4 weeks old, were injected with MgCl2 (2 mM Mg/kg body weight) and exposed to 100% O2 at 75 lb/in2 (approximately 5 atm). Compared to saline-injected controls, ...
Pulmonary oxygen toxicity in chickens and rabbits
hyperbaric animal rabbit chicken Pulmonary oxygen toxicity
2009/7/17
Chickens exposed to hyperbaric oxygen (3 to 5 ATA) or to 100percent oxygen at atmospheric pressure for prolonged periods showed no pathologic pulmonary damage, although hydrogen peroxide did accumulat...
Acute oxygen toxicity in a saturation diver working in the North Sea
exercise pulmonary human oxygen toxicity commercial saturation
2009/7/16
A commercial diver taking part in a saturation dive (O2-He) was exposed intermittently to 1.4 b of oxygen for a total of 55 h. He developed the syndrome associated with oxygen pulmonary toxicity. Deta...
Acetazolamide and CO2 in hyperbaric oxygen toxicity
Acetazolamide oxygen toxicity carbon dioxide
2009/7/16
The role of CO2 in hyperbaric oxygen toxicity was investigated by administering acetazolamide (Diamox), Tris buffer [tris(hydroxymethyl)aminomethane], and sodium bicarbonate by i.p. injection, and by ...
New perspectives on hyperoxic pulmonary toxicity--a review.
CNS oxygen toxicity in the rat: role of ambient illumination
hyperbaric CNS oxygen toxicity Central Nervous System animal rat
2009/7/14
The effect of ambient illumination on sensitivity to CNS oxygen toxicity was studied in awake male rats. Continuous recording of the EEG was obtained with chronically implanted cortical electrodes. Th...
Central nervous system oxygen toxicity in closed circuit scuba divers II
human oxygen toxicity Central nervous system
2009/7/14
Central nervous system oxygen toxicity is currently the limiting factor in underwater swimming/diving operations using closed-circuit oxygen equipment. A dive series was conducted at the Navy Experime...
Blood glucose as a predictive measure for central nervous system oxygen toxicity in conscious rats
hyperbaric oxygen toxicity rats Blood glucose
2009/7/14
Blood glucose concentration was measured during continuous electrocorticographic (ECoG) recording in conscious rats exposed to 3 and 5 atmosphere absolute oxygen (ATA O2). The preconvulsive oxygen-ind...
CNS oxygen toxicity in oxygen-inert gas mixtures
oxygen toxicity nitrogen hyperbaric animal rat
2009/7/14
Central nervous system oxygen toxicity in hyperbaric oxygen-inert gas mixtures was studied by exposing male rats to various gas mixtures having the same oxygen partial pressure and varying pressures o...
Visual reaction time performance preceding CNS oxygen toxicity
human oxygen toxicity visual
2009/7/14
The visual reaction time performance of divers experiencing CNS oxygen toxicity was assessed during the development of closed-circuit 100percent oxygen breathing diving schedules at the U.S. Navy Expe...
Central nervous system oxygen toxicity in the resting rat: postponement by intermittent oxygen exposure
pulmonary oxygen toxicity seizure hyperbaric outcomes nitrox
2009/7/14
Intermittent O2 breathing is a proven means of delaying pulmonary O2 toxicity during exposure to hyperbaric oxygen. The effect of an intermittent exposure in the pressure range toxic to the CNS was st...
High ambient pressure of 41 bar increases the cerebral toxicity of penicillins
animal rat drug
2009/7/10
Sodium benzylpenicillin, cloxacillin, and azlocillin were infused intravenously in awake rats at 1 and 41 bar until they convulsed. The doses necessary to elicit convulsions were significantly lower a...
A test for variations in individual sensitivity to hyperbaric oxygen toxicity
HBO oxygen toxicity hyperbaric outcomes human
2009/6/12
It has been suggested that some individuals have above-average sensitivity to hyperbaric oxygen toxicity. An extensive human study completed at the Naval Experimental Diving Unit (NEDU) tested human t...
