This case report describes the successful management of an out-of-hospital arrest in a diver following a suspected arterial gas embolism (AGE). It illustrates both the inherent risks of diving and the importance of prompt and effective implementation of the "chain of survival" from bystanders. Rapid on-scene responses from paramedics and helicopter emergency medical services facilitated prompt evacuation to a Category 1 (multiplace) recompression chamber (RCC) where specialists in cardiology and hyperbaric medicine were available...

BACKGROUND: Doppler ultrasound is used currently in decompression research for the evaluation of venous gas emboli (VGE). Estimation of heart rate from post-dive Doppler ultrasound recordings can provide a tool for the evaluation of physiological changes from decompression stress, as well as aid in the development of automated VGE detection algorithms that relate VGE presence to cardiac activity. METHOD: An algorithm based on short-term autocorrelation was developed in MATLAB to estimate the heart rate in post-dive precordial Doppler ultrasound...

BACKGROUND: Rheumatoid arthritis is a debilitating and destructive disease for which limited therapeutic options exist. OBJECTIVE: This report summarizes serial magnetic resonance imaging (MRI) findings from nine study participants treated with hyperbaric oxygen (HBO2) therapy and expands upon an earlier pilot study that showed improvement in disease activity and joint pain as determined by multiple, validated clinical measures. METHODS: Rheumatoid arthritis patients received 30 hyperbaric oxygen treatments over six to 10 weeks...

INTRODUCTION: Deep second-degree burn injuries are the most challenging situations for the burn surgeon in the treatment of adult cases. While waiting for spontaneous closure increases the risk of hypertrophic scar and keloid, early excision and grafting pose the risk of donor site wound and permanent color differences. Unlike many studies in the literature, the current study was planned in a way to minimize factors other than burn wounds to investigate the effect of adding hyperbaric oxygen (HBO2) therapy to conventional treatment in deep second-degree burn wounds...

BACKGROUND AND OBJECTIVE: Hyperbaric oxygen (HBO2) has been the subject of research in many areas of dentistry. HBO2 seems to be a useable, additional treatment method. However, there are still no certain conclusions and clear guidelines for procedures. The aim of the study was to collect current literature assessing the use of hyperbaric oxygen therapy in the treatment of periodontitis. MATERIALS AND METHODS: The following review was performed using medical databases Medline via PubMed and Google Scholar...

INTRODUCTION: Radiation therapy to the pelvis can result in radiation-induced vaginal soft tissue necrosis. This significantly impacts quality of life. Studies evaluating the efficacy of HBO2 are limited. METHODS: In this retrospective report, we reviewed the medical records of patients treated with once-daily HBO2 for radiation-induced vaginal soft tissue necrosis. We included females between the ages of 18 to 90 with history of pelvic cancer treated with radiotherapy and resultant soft tissue radionecrosis...

Acute carbon monoxide (CO) intoxication may result in delayed neurological sequelae, which can include amnesia, ataxia, aphasia, emotional lability, disorientation, dysphagia, and other manifestations. A 27-year-old man reported symptoms of aphasia with agraphia and alexia in a review after CO intoxication. The patient received outpatient speech therapy, as well as repeated sessions of hyperbaric oxygen for 15 days, interspersing speech therapy with hyperbaric oxygen therapy for two months. After this period of combined treatment the aphasic symptomatology remitted, and oral and written language was normal...

As the UHMS observes the distinguished anniversary of the publication of 50 volumes of the Undersea and Hyperbaric Medicine Journal, two of our past editors take a look at the evolution of our flagship publications.

Central retinal artery occlusion (CRAO) is a relatively rare emergent condition of the eye resulting in sudden painless vision loss. This vision loss is usually dramatic and permanent, and the prognosis for visual recovery is poor. A wide variety of treatment modalities have been tried over the last 100 years with little to no success, with the exception of hyperbaric oxygen therapy. The optimum number of treatments will vary depending on the severity and duration of the patient's symptoms and the degree of response to treatment...

OBJECTIVE: Hyperbaric oxygen (HBO2) is used in several clinical and research fields. This study aimed to analyze the 100 most-cited hyperbaric-related publications of the past 10 years to understand the trends in HBO2 research. METHODS: This was a literature review. All publication and citation data were retrieved from the Scopus database. Publications with "hyperbaric oxygen," "hyperbaric oxygenation," "HBO," and "HBOT" in the title, abstract, or keywords published between January 01, 2011, and December 31, 2020, were enrolled...

BACKGROUND: Early recompression therapy is suggested for a better clinical outcome of decompression sickness (DCS) patients. This study analyzed the efficacy of our 24-hour on-call system for early recompression therapy. METHODS: We conducted a single-center retrospective cohort study. They were classified into DCS Type I versus Type II, duty time versus non-duty time groups based on the time of emergency department (ED) admission, and hospitalization versus discharge groups according to clinical outcomes...

INTRODUCTION: We aimed to assess the efficacy and safety of a standardized hyperbaric oxygen (HBO2) therapy protocol in patients with retinal artery occlusion (RAO). METHODS: A retrospective study was conducted in our tertiary care center from July 2016 to September 2019. Patients experiencing central RAO and branch RAO for less than seven days were included. Once the diagnosis was made, patients were urgently referred to the HBO2 department to receive a first 90-minute HBO2 session at a pressure of 2...

PURPOSE: The aim of our study is to investigate the effects of hyperbaric oxygen (HBO2) therapy on retinal layers in healthy eyes. METHOD: Thirty patients who were taken to outpatient HBO2 for any indication were included in the study. All patients underwent 10 sessions of HBO2; 20 healthy patients were taken as the control group. We used the spectral-domain optical coherence tomography (SD-OCT) to obtain automated measurements of thickness for each retinal layer - i...

INTRODUCTION: Several causes can lead to carbon monoxide (CO) intoxication. A first-line treatment option for such intoxications is hyperbaric oxygenation (HBO2) therapy. The COVID-19 pandemic has been changing everyday life in Germany since March 2020, mainly caused by statutory provisions. Our aim was to review whether these changes have an influence on the causes and frequency for the development of CO intoxication. METHODS: We retrospectively analyzed the data of patients who were treated for CO intoxication in our institution between April 2019 and March 2021...

Arsenic (As) is a toxic substance that damages the human body through exposure to drinking water. This exposure damages many organs and tissues in the body, especially the liver and kidneys. Hyperbaric oxygen (HBO2) therapy is a treatment method that acts by reducing oxidative stress parameters in tissues with high-pressure oxygen. Based on this, our study aimed to investigate the effectiveness of HBO2 on liver and kidney tissues with chronic arsenic toxicity. In the study 24 male Wistar albino rats (220-300 g, two to three months old) were equally divided into four groups: Control; As; HBO2; and As+HBO2...

PURPOSE: In a disabled submarine scenario, a pressurized rescue module (PRM) may be deployed to rescue survivors. If the PRM were to become disabled, conditions could become hot and humid exposing the occupants to heat stress. We tested the hypothesis that the rise in core temperature and fluid loss from sweating would increase with rising dry bulb temperature. METHODS: Twelve males (age 22 ± 3 years; height 179 ± 7 cm; mass 77.4 ± 8.3 kg) completed this study...
