Radiotherapy is a widely recognised treatment for non-melanoma skin cancer. We report three cases of radiation-induced skin ulcers in which hyperbaric oxygen therapy was administered in 90-min sessions, 5 days a week at 2.4 absolute atmospheres in a multiplace hyperbaric chamber. Hyperbaric oxygen therapy is an outpatient treatment that does not displace other classical treatments and may be used as an adjunct therapy.

OBJECTIVE: Hyperoxia is known to influence cardiovascular and endothelial function, but it is unknown if there are differences between younger and older persons. The aim of this study was to monitor changes in myocardial diastolic function and flow-mediated dilatation (FMD) in younger and elderly volunteers, before and after exposure to relevant hyperbaric hyperoxia. METHODS: 51 male patients were separated into two groups for this study. Volunteers in Group 1 (n=28, mean age 26 ±6, "juniors") and Group 2 (n=23, mean age 53 ±9, "seniors") received standard HBO₂ protocol (240kPa oxygen)...

BACKGROUND: Central retinal artery occlusion (CRAO) is an ophthalmological emergency, the retinal analog of a stroke. To date there is no consensus or national guidelines on how this disorder should be managed. As academic neurologists and ophthalmologists treat CRAO frequently, we set out to understand how these clinicians approach patients with CRAO with a national survey. METHODS: We identified university-associated teaching hospitals offering vascular neurology, neuro-ophthalmology and/or retina fellowships in the US and asked the directors of the programs to respond to questions in an open response format to profile the acute management of CRAO at their institution...

INTRODUCTION: Perfluorocarbons (PFC) are fluorinated hydrocarbons that dissolve gases to a much greater degree than plasma and hold promise in treating decompression sickness (DCS). The efficacy of PFC in a mixed gender model of DCS and safety in recompression therapy has not been previously explored. METHODS: Swine (25 kg; N = 104; 51 male and 53 female) were randomized into normal saline solution (NSS) or PFC emulsion treatment groups and subjected to compression on air in a hyperbaric chamber at 200 fsw for 31 min...

OBJECTIVE: To investigate the effects of N-butylphthalide (NBP) on cognitive function in acute severe carbon monoxide (CO) poisoning rats and its mechanism. METHODS: 120 health Sprague-Dawley (SD) rats were randomly divided into three groups (n = 40): normal control group (NC group), CO poisoning group (CO group) and NBP treatment group (NBP group). The acute severe CO poisoning model was established in a hyperbaric oxygen chamber by intoxicated with 1 000 ×10-6 CO for 40 minutes, followed with 3 000 ×10-6 CO for another 20 minutes, and then received hyperbaric oxygen therapy 1...

Decompression sickness (DCS) occurs when ambient pressure severely reduces during diving and aviation. Hyperbaric oxygen (HBO) pretreatment has been proven to exert beneficial effects on DCS in rats via heat-shock proteins (HSPs). We hypothesize that HBO pretreatment will also reduce DCS via HSPs in swine models. In part 1, six swine were subjected to a session of HBO treatment. HSP 32, 60, 70 and 90 were detected, before and at 6, 12, 18, 24 and 30 h following exposure in lymphocytes. In part 2, another ten swine were randomly assigned into 2 groups, 5 in each...

BACKGROUND: Hyperbaric oxygenation (HBO₂) involves breathing 100% oxygen under elevated ambient pressure in a hyperbaric chamber, thereby dissolving oxygen in the plasma. This results in an increase of arterial partial pressure of oxygen (pO₂). Though well established in experimental studies, HBO₂ treatment for ischemic stroke is still under discussion. METHODS: From 2002-2014 HBO₂ (2.2 bar, 90 minutes one/day; average number per patient: 4.7) was applied in 49 consecutive patients (32 males, 17 females, mean age: 68...

Objective: Use test methods to assess the oxygen compatibility of various wound care products. Approach: There are currently no standard test methods specifically for evaluating the oxygen compatibility and safety of materials under hyperbaric oxygen (HBO) conditions. However, tests such as the oxygen index (OI), oxygen exposure (OE), and autogenous ignition temperature (AIT) can provide useful information. Results: The OI test measures the minimum oxygen concentration that will support candle-like burning, and it was used to test 44 materials...

INTRODUCTION: Diving is an activity performed in more than 1 atmosphere absolute pressure (ATA) either underwater or in a hyperbaric chamber. We aimed to compare lung function values of trained divers in 1.5 ATA hyperbaric chambers after inhaling 100% oxygen and regular air. METHODS: This experimental study with crossover design involved 18 trained divers in 1.5 ATA hyperbaric room, which is equivalents to a 5-meter depth. The eighteen subjects as the supplementation group, using oro-nasal mask, inhaled 100% oxygen for 30 minutes followed by a one-day washout period...

BACKGROUND AIMS: Umbilical cord blood (UCB) provides an alternative source for hematopoietic stem/progenitor cells (HSPCs) in the treatment of hematological malignancies. However, clinical usage is limited due to the low quantity of HSPCs in each unit of cord blood and defects in bone marrow homing. Hyperbaric oxygen (HBO) is among the more recently explored methods used to improve UCB homing and engraftment. HBO works by lowering the host erythropoietin before UCB infusion to facilitate UCB HSPC homing, because such UCB cells are not directly exposed to HBO...

Background: The Brain uses 20% of the total oxygen supply consumed by the entire body. Even though, <10% of the brain is active at any given time, it utilizes almost all the oxygen delivered. In order to perform complex tasks or more than one task (multitasking), the oxygen supply is shifted from one brain region to another, via blood perfusion modulation. The aim of the present study was to evaluate whether a hyperbaric oxygen (HBO) environment, with increased oxygen supply to the brain, will enhance the performance of complex and/or multiple activities...

REVIEW
Ran Arieli
Decompression illness (DCI) occurs following a reduction in ambient pressure. Decompression bubbles can expand and develop only from pre-existing gas micronuclei. The different hypotheses hitherto proposed regarding the nucleation and stabilization of gas micronuclei have never been validated. It is known that nanobubbles form spontaneously when a smooth hydrophobic surface is submerged in water containing dissolved gas. These nanobubbles may be the long sought-after gas micronuclei underlying decompression bubbles and DCI...

BACKGROUND: High-altitude flight simulation familiarizes military trainees with the symptoms of hypoxia to prepare them for emergency situations. Decompression sickness (DCS) can occur as a result of these simulations. In cases when ground-level supplemental oxygen does not resolve symptoms, hyperbaric oxygen (HBO) therapy is indicated. Many military hyperbaric chambers have been closed because of cost reductions, necessitating partnerships with community hospitals to ensure access to treatment...

Skin lesions are visual clinical manifestations of decompression sickness (DCS). Comprehensive knowledge of skin lesions would give simple but strong clinical evidence to help diagnose DCS. The aim of this study was to systematically depict skin lesions and explore their pathophysiological basis in a swine DCS model. Thirteen Bama swine underwent simulated diving in a hyperbaric animal chamber with the profile of 40 msw-35 min exposure, followed by decompression in 11 min. After decompression, chronological changes in the appearance of skin lesions, skin ultrasound, temperature, tissue nitric oxide (NO) levels, and histopathology were studied...

We report the case of a 54-year-old male compressed-air worker with gas bubbles detected by computed tomography (CT). He had complained of strong abdominal pain 30 minutes after decompression after working at a pressure equivalent to 17 meters of sea water for three hours. The initial CT images revealed gas bubbles in the intrahepatic portal vein, pulmonary artery and bilateral femoral vein. After the first hyperbaric oxygen treatment (HBO₂ at 2.5 atmospheres absolute/ATA for 150 minutes), no bubbles were detected on repeat CT examination...
