Hyperbaric oxygen as prophylaxis or treatment for radiation myelitis
HBO radionecrosis radiation myelitis
2009/6/12
This animal study was designed to investigate HBO as a treatment or prophylaxis for radiation myelitis. All animals received identical spinal cord radiation doses of 69 Gy in 10 daily fractions. Group...
Modification of oxygen tolerance in rats by adaptation to combined hypoxia and hypercapnia
pulmonary hypoxia oxygen toxicity hypercapnia carbon dioxide animal rat
2009/6/12
Tolerance to 100% O2 or to O2 with 60 torr PICO2 (O2-CO2) was determined at pressures of 1.0-4.0 atm abs in normal rats and in rats adapted to combined hypoxia and hypercapnia (HHA) before O2 or O2-CO...
Does hyperbaric oxygen have a cancer-causing or -promoting effect? A review of the pertinent literature
HBO hyperbaric literature review cancer
2009/6/12
We reviewed all known published reports or studies related to a possible cancer-causing or growth-enhancing effect by hyperbaric oxygen. Published articles were retrieved using Medline searches for th...
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...
Effect of air,heliox,and oxygen breathing on air bubbles in aqueous tissues in the rat
helium heliox retinal eye decompression diffusion decompression sickness animal rat air
2009/6/12
Our purpose was to examine the behavior of air bubbles in three non-lipid tissues (skeletal muscle, tendon, and the anterior chamber of the eye) during breathing of air, helium-oxygen (heliox, 80:20),...
Protective effect of oxygen and heliox breathing during development of spinal decompression sickness
decompression sickness helium heliox oxygen spinal cord animal rat air
2009/6/12
A rat model of spinal decompression sickness (DCS) allows study of spinal cord function for at least 3 h after decompression to 1 atm abs (101 kPa) after an exposure to air at 3.8 atm abs (385 kPa) fo...
Hyperbaric oxygen therapy in hemorrhagic radiation cystitis: a report of 20 cases
HBO multiplace cystitis radionecrosis radiation hyperbaric
2009/6/12
Radiation cystitis with macroscopic hematuria has been a frustrating clinical problem for urologists. Since 1985 hyperbaric oxygen (HBO) has been used to treat this disease, showing favorable results....
Failure of normobaric oxygen therapy to reduce ischemic brain damage in rats
outcomes ischemic brain damage animal rat
2009/6/12
We investigated the effects of 24-h oxygen therapy on focal cerebral ischemia in rats. Under halothane anesthesia, a 3-0 nylon thread was introduced into the neck internal carotid artery to occlude th...
Hyperbaric oxygen therapy is used in ophthalmology in ischemic pathologies of the anterior and posterior segments. Our experiment was done on a healthy group of volunteers aged between 10 and 50 yr. W...
Influence of hyperbaric oxygen on left ventricular contractility, total coronary blood flow, and myocardial oxygen consumption in the conscious dog
HBO CO2 carbon dioxide hyperbaric cardiac output air dog animal myocardial contractility
2009/6/12
It is known that hyperbaric oxygenation (HBO) decreases total coronary blood flow (TCBF) and cardiac output (CO). To determine whether this is related to an alteration in myocardial contractility, 10 ...
Effect of radical scavengers and hyperbaric oxygen on smoke-induced pulmonary edema
HBO pulmonary hyperbaric smoke radical scavenger animal rabbit
2009/6/12
Respiratory complications, especially pulmonary edema, account for over 50% of mortalities in inhalation injuries. This study was conducted to determine the effect of free radical scavengers and hyper...
Probable lung injury by long-term exposure to oxygen close to 50 kilopascals
saturation decompression oxygen toxicity pulmonary
2009/6/12
To investigate the possibility of lung injury after long-term saturation dives where oxygen partial pressure was kept between 42 and 50 kPa, we measured lung volumes, diffusing capacity (DLCO/VA), and...
Salutary consequences of oxygen therapy on the long-term outcome of hemorrhagic shock in awake, unrestrained rats
oxygen toxicity hypoxia outcomes hemorrhagic shock animal rat
2009/6/12
Decreased oxygen delivery and cellular hypoxia are major factors in the pathophysiology of shock. We studied the effects of 100% O2 at 0.1 and 0.3 MPa (1 and 3 atm abs) in severe hemorrhagic shock in ...
