OBJECTIVE To evaluate the mRNA expression of T helper (Th)1, Th2, and Th17 cell-associated inflammatory mediators in cells of bronchoalveolar lavage fluid samples collected from healthy horses exposed to hyperbaric oxygen (HBO) and to monitor blood oxygen concentration during and following HBO therapy. ANIMALS 8 healthy horses. PROCEDURES In a randomized controlled crossover design study, each horse was exposed (beginning day 1) to 100% oxygen at a maximum of 3 atmospheres absolute (304 kPa) daily for 10 days or ambient air at atmospheric pressure in the HBO chamber for an equivalent amount of time (control)...

A number of studies have reported benefits associated with the application of hyperbaric oxygen treatment (HBO) delivered immediately prior to radiation therapy. While these studies provide evidence that pre-treatment with HBO may be beneficial, no measurements of intratumoral pO2 were carried out and they do not directly link the apparent benefits to decreased hypoxic fractions at the time of radiation therapy. While there is empirical evidence and some theoretical basis for HBO to enhance radiation therapy, without direct and repeated measurements of its effects on pO2, it is unlikely that the use of HBO can be understood and optimized for clinical applications...

Carbon monoxide acute intoxication is a common cause of accidental poisoning in industrialized countries and sometimes it produces a real mass casualty incident. The incident described here occurred in a church in the province of Verona, when a group of people was exposed to carbon monoxide due to a heating system malfunction. Fifty-seven people went to the Emergency Department. The mean carboxyhemoglobin (COHb) level was 10.1±5.7% (range: 3-25%). The clinicians, after medical examination, decided to move 37 patients to hyperbaric chambers for hyperbaric oxygen (HBO) therapy...

INTRODUCTION: Osteoradionecrosis of the jaws produces a considerable amount of esthetic as well as functional deficits seriously affecting quality of life of the patient. Cases are often notoriously difficult to treat and manage owing to associated comorbidities of the patient, post irradiation fibrosis and decreased vascularity at the site, which complicates free tissue flap and graft transfer, that subsequently succumb to failure. Hyperbaric oxygen therapy (HBOT), in which 100 % oxygen is administered by mask under 2...

The U.S. territory of Guam attracts thousands of military and civilian divers annually and is home to the only recompression facility within a 5,000-km radius that accepts critically injured dive casualties. As recompression chambers are confined spaces and standard use of electrical cardioversion cannot be used, cardiac resuscitation at depth must deviate from advanced cardiovascular life support (ACLS) algorithms. Furthermore, many hyperbaric chambers that accept dive casualties are in remote locations, a situation that requires providers to approach cardiac resuscitation in a different way when compared to an in-hospital or ICU setting...

Hyperbaric oxygen therapy is the primary treatment for arterial gas embolism, decompression sickness and acute carbon monoxide poisoning. Though there has been a proliferation of hyperbaric centers throughout the United States, a scarcity of centers equipped to treat emergency indications makes transport of patients necessary. To locate and characterize hyperbaric chambers capable of treating emergency cases, a survey of centers throughout the entire United States was conducted. Using Google, Yahoo, HyperbaricLink and the UHMS directory, a database for United States chambers was created...

Carbon monoxide poisoning is one of the most frequent types of poisoning caused by gases. Exposure of a pregnant woman to carbon monoxide is connected with transmission of this gas to her fetus what may cause oxygen deficiency, and further, the damage to its organs. The article describes a case of carbon monoxide poisoning of a 28-weeks pregnant woman who was treated in a hyperbaric chamber. Therapy was successful and the woman gave birth to a healthy, full term infant. In case of poisoning to a pregnant woman the above seems to be the most advantageous solution...

Oxygen is an essential gas. Oxygen is also a biological medicine. Hyperbaric oxygen therapy is a treatment which is based on the respiration of pure oxygen in a particular pressurised environment (hyperbaric chamber). The pressure allows the diffusion of oxygen into the blood at a concentration which is ten/fifteen/twenty times the normal level. The increase in oxygen in bodily liquids stimulates the synthesis of a gas, nitric oxide (NO), which has a powerful anti-inflammatory effect and promotes the formation of new blood vessels (also through the employment of stem cells) thus accelerating the healing of wounds...

INTRODUCTION: Radiation-induced hemorrhagic cystitis is a serious side effect of radiation therapy. Anemia requiring transfusion can ensue. Treatment methods include bladder irrigation, fulguration, and hyperbaric oxygen (HBO2) therapy. Failure of treatment leads to cystectomy associated with a high risk of severe complications (42%) and mortality (16%). Continuous bladder irrigation (CBI) is often required to prevent further clot formation. HBO2 supports the healing process of radiation cystitis...

Hyperbaric oxygen therapy (HBOT) is a scientifically justified and internationally established therapy, which is however not well-known thus rarely used in Germany. During a HBOT, the ambient pressure is raised while the patient breathes 100% O2, causing tissue partial oxygen pressure (ptO2) to increase distinctly. Through that, various pressure- and O2-associated processes are initiated. Herein 3 case studies are described that illustrate the mechanism of action and the range of applications of HBOT.
