Effects of hyperbaric oxygen on S-180 sarcoma in mice
Sarcoma 180 hyperbaric superoxide dismutase animal mice
2009/6/9
The contents of oxygen free radicals (OFRs) and malondialdehyde (MDA) in S-180 sarcoma tissues were measured in four groups of mice: an untreated normoxic group, a normoxic hyperbaric group, a hyperba...
Brainstem auditory evoked potentials during a helium-oxygen saturation dive to 450 meters of seawater
saturation helium heliox ear high pressure nervous syndrome auditory evoked potentials
2009/6/9
When divers are exposed to extreme atmospheric pressures they may exhibit symptoms of the high pressure nervous syndrome (HPNS). Although clinical HPNS symptoms are well described, little is known abo...
Brain computerized tomography after hyperbaric oxygen therapy for carbon monoxide poisoning
HBO carbon monoxide computerized tomography hyperbaric outcomes
2009/6/9
The role of brain computerized tomography (CT) imaging in predicting clinical outcome was investigated in patients receiving hyperbaric oxygen therapy for serious carbon monoxide (CO) poisoning. From ...
An alternative oxygen supply technique for the difficult patient
multiplace monoplace chamber oxygen tracheostomy cuff case report
2009/6/9
A modified oxygen delivery system was developed for a patient too claustrophobic for the monoplace chamber or the hood in the multiplace chamber. The adaptation delivered O2 through the patient's trac...
Modulation of sensitivity to hyperbaric oxygen by CO2 in newborn rats
HBO CO2 carbon dioxide pulmonary hyperbaric animal rat
2009/6/9
We examined the modifying effects of CO2 on the CNS and pulmonary manifestations of hyperbaric oxygenation (HBO) in newborn rats. Four- to seven-day-old rats were exposed to HBO with inspired PCO2 (PI...
Hyperbaric oxygen, oxygen-ozone therapy, and rheologic parameters of blood in patients with peripheral occlusive arterial disease
HBO hyperbaric arterial disease
2009/6/9
For many years, clinical practice has consolidated the use of both hyperbaric oxygen and oxygen-ozone therapy in the treatment of peripheral occlusive arterial disease (POAD). We investigated the infl...
Use of transcutaneous pressure of oxygen in the evaluation of edematous wounds
HBO hyperbaric wound air
2009/6/9
Transcutaneous pressure of oxygen (Ptco2) was measured in edematous wounds before and after a regimen of hyperbaric oxygen (HBO2) therapy, in patients breathing normobaric air (AIR), 100% normobaric o...
Hyperbaric oxygen an adjunctive treatment for delayed radiation injuries of the abdomen and pelvis
radionecrosis radiationp hyperbaric
2009/6/9
Radiation therapy is often utilized as adjunctive or primary treatment for malignancies of the abdomen and pelvis. Radiation complications are infrequent, but can be life threatening or significantly ...
Central nervous system oxygen toxicity during hyperbaric treatment of patients with carbon monoxide poisoning
carbon monoxide multiplace seizure hyperbaric oxygen toxicity
2009/6/8
Hyperbaric oxygen (HBO2) is associated with a recognized risk for clinical central nervous system (CNS) toxicity. The risk for oxygen convulsions during routine hyperbaric treatment of most routine co...
Pneumatosis cystoides intestinalis confined to the small intestine treated with hyperbaric oxygen
hyperbaric Pneumatosis cystoides intestinalis small intestine gastrointestinal disease
2009/6/8
Pneumatosis cystoides intestinalis is a rare disease characterized by the presence of multiple intramural gas-filled cysts in the gastrointestinal tract. The etiology remains unknown, but the disease ...
Measurement of oxygen concentration in delivery systems used for hyperbaric oxygen therapy
hyperbaric equipment oxygen delivery breathing mask breathing hood
2009/6/8
Efficient delivery of oxygen is important during hyperbaric oxygen therapy. We compared two systems in common use, and developed a method to ensure that O2 delivery was adequate during treatment. The ...
Effect of 12 atmospheres helium-oxygen on the response of mice to convulsant drugs
helium heliox helium convulsant drug air animal mice
2009/6/8
The mechanism by which 12 atm abs of a helium-oxygen gas mixture (heliox) antagonizes behavioral effects of ethanol is unknown. Although the threshold for pressure-reversal of general anesthesia and e...
Transcranial Doppler sonographic measurements of middle cerebral artery flow velocity during hyperbaric oxygen exposures
hyperbaric Transcranial Doppler seizure oxygen
2009/6/8
In the present study, experimental exposures to hyperbaric oxygen (HBO2) were performed (30-min exposure to 2.8 bar (280 kPa) pure oxygen). During all phases of the experiment, blood flow velocity in ...
