{"title":"A Critical Look at Soft-Sided and Hard-Sided \"Mild\" Hyperbaric Chambers - Risks, Regulations, and Ethical Oversights.","authors":"Ryan A Murray","doi":"","DOIUrl":"","url":null,"abstract":"Soft-sided hyperbaric chambers, as well as some hard-sided (mild) hyperbaric chambers, which are low-pressure, hyperbaric chambers that are typically designed for operational pressures of 3-5psi, have gained popularity in recent years. They are marketed as safe and effective for various conditions but lack compliance with critical regulatory and safety standards and codes. This raises concerns regarding patient safety, the validity of manufacturers' claims, and the ethical obligations of medical professionals and regulators.This manuscript examines the risks, regulatory gaps, and ethical implications of using soft-sided fabric chambers, as well as hard-sided (mild) hyperbaric chambers, focusing on their failure to meet FDA clearance, NFPA 99 & NFPA 101 codes, and ASME-PVHO standards.A comprehensive review of regulatory guidelines, safety reports, and marketing practices was conducted, supplemented by illustrations of adverse events linked to the use of these devices. Ethical principles, including beneficence, non-maleficence, and informed consent, were applied to analyze the responsibilities of manufacturers, healthcare providers, patients, and regulators.These chambers are often marketed with misleading claims about their efficacy and safety. Their non-compliance with FDA clearance, as well as not following industry standards and safety codes increases the risk of patient harm, including otic and pulmonary barotrauma, suffocation, fire hazards, structural failure, and, in extreme cases, death. Regulatory oversight remains inconsistent, allowing manufacturers to exploit loopholes. Furthermore, ethical concerns arise when patients are not fully informed of the limitations and risks of these devices.The widespread use of these hyperbaric chambers poses significant safety and ethical challenges. Stricter enforcement of regulatory standards and codes, transparent marketing practices, and ethical accountability from healthcare providers and manufacturers are essential to protect patients and uphold public trust in medical technologies.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"53 3","pages":"523-534"},"PeriodicalIF":0.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149117301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each group was further randomized into four time-point subgroups (6 hours, 24 hours, three days, seven days). Basso, Beattie, Bresnahan (BBB) scores and DTI parameters, including fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD), and mean diffusivity (MD), were collected and analyzed. Spinal cord tissues were processed for hematoxylin, eosin, and Nissl staining.Results: HBO-PC groups exhibited higher FA values than SCI groups at different time points (all p < 0.05). RD and MD values were higher in SCI groups than in HBO-PC groups from 24 hours to 7 days (all p < 0.05). The SCI group showed more pronounced inflammatory cell infiltration and neuronal atrophy than the HBO-PC group. The number of surviving neurons in the injured spinal cord in the HBO-PC group was higher than that in the SCI group at each time point (all p < 0.05). FA values were negatively correlated with BBB scores, while RD and MD values were positively correlated with BBB scores.Discussion: HBO-PC can reduce neuronal cell death and promote nerve function recovery. DTI can quantitatively evaluate HBO-PC's protective effect in rats with SCI.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"53 3","pages":"455-466"},"PeriodicalIF":0.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149117266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe type II DCS, characterized by neurological involvement, is particularly disabling and life - threatening. Traditional decompression treatments often show limitations in severe cases. This case report highlights the effectiveness of saturation diving decompression in the treatment of such severe DCS.Case report: A 33-year-old male diver experienced severe type II decompression sickness (DCS) following an emergency ascent from a depth of 56 meters of seawater (msw) due to an underwater explosion. The condition was characterized by coma, as well as bleeding from the nose and ears. Initial treatment utilizing a 60 msw recompression protocol demonstrated limited efficacy, with symptom recurrence observed during the decompression process. Subsequently, a 15 msw air saturation diving decompression treatment was implemented, which extended the stay time at each station to facilitate the desaturation of gas bubbles. The patient's symptoms improved significantly. Repeat MRI 4 days later showed a ≥50 % reduction in lesion volume. The patient was discharged neurologically intact on day 11 and, at 3-month follow-up, had resumed land-based duties without sequelae.Discussion: This case underscores the effectiveness of saturation diving decompression in the management of severe DCS, highlighting the critical role of ultra-high-pressure recompression and prolonged desaturation periods.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"53 3","pages":"417-422"},"PeriodicalIF":0.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149117325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Hyperbaric Oxygen Treatment for Enhancing Athletic Recovery: A Systematic Review and Meta-Analysis.","authors":"Shrinit Babel, Gerardo Bosco, Enrico Camporesi","doi":"","DOIUrl":"","url":null,"abstract":"Introduction: Hyperbaric oxygen treatment (HBO₂) uses increased atmospheric pressure and fractional oxygen to enhance tissue oxygen delivery. HBO₂ has gained attention as a tool for athletic recovery and performance, but past reviews in the literature are limited or inconclusive. This systematic review and meta-analysis aim to provide an update and assess the effect of HBO₂ on athletic recovery.Methods: Literature searches were performed across PubMed, Cochrane Central, Google Scholar, and Embase (January 1, 2015-September 15, 2024), following PRISMA guidelines. Studies included healthy athletes undergoing HBO₂ to assess athletic performance, metabolic recovery, and physiological responses. Quality assessment was performed using Cochrane's risk of bias tools (ROB2 and ROBINS-1). A meta-analysis with subgroup analyses by age, body mass index, and body fat mass percentage was conducted, along with a meta-regression examining HBO₂ protocol characteristics and outcomes.Results: Eleven met the eligibility criteria; six studies were included in the meta-analysis. The meta-analysis showed that HBO₂ significantly reduced post-recovery blood lactate levels (effect size: -1.71; 95% CI: -3.10 to -0.32). Subgroup analysis revealed that younger athletes and those with lower fat mass receiving HBO₂ exhibited significant reductions in post-recovery lactate levels. Meta-regression was inconclusive but suggested treatment effect heterogeneity based on HBO₂ protocol characteristics. HBO₂ showed limited application in short-term power output and force production.Discussion: Hyperbaric oxygen treatment is an efficient method for improving athletic performance, particularly by reducing post-exercise lactate levels, thereby supporting faster metabolic recovery. Future studies should focus on standardized protocols, diverse populations, and long-term outcomes to better understand HBO₂'s potential in orthopedics and sports medicine.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"53 2","pages":"305-318"},"PeriodicalIF":0.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148347074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Mixed Compartment Syndromes and Neuropathy Resolution With Hyperbaric Oxygen.","authors":"Michael Strauss, Arielle Sass, Katherine Wilson, Stuart Miller","doi":"","DOIUrl":"","url":null,"abstract":"Introduction: Skeletal muscle compartment syndrome (SMCS) and exertional compartment syndrome (ECS) are two distinct conditions. This case report describes a situation in which both conditions resulted from the same triggering events. The importance of this case lies in the fact that the residual neuropathy associated with the SMCS resolved after a single hyperbaric oxygen (HBO₂) treatment.Case report: This report was generated from a retrospective analysis of the patient's combined compartment syndromes, SMCS and ECS, residual functional deficit, and resolution of the latter with HBO₂ treatment. Severe leg pain developed after two strenuous back-to-back ballet and gymnastics sessions. Similar leg pains of lesser severity had occurred previously but always resolved after the activity was stopped. During this episode, the pain subsided; however, the next day, the patient began to walk with a steppage gait. The athlete received HBO₂ treatment, which restored her peroneal nerve function. Subsequently, the patient underwent an ECS evaluation, bilateral leg fasciotomies, and returned to athletic activities without symptoms.Discussion: A residual nerve palsy can result from an SMCS. This symptom, combined with the rapid resolution of pain symptoms consistent with an ECS, suggests that both problems resulted from the same cause. The delayed onset of the drop foot was attributed to the self-perpetuating cycle of ischemia and edema associated with the lag phase of the SMCS. The resolution of the peroneal nerve palsy with HBO₂ treatment adds additional validation for the roles of HBO₂ in SMCS.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"53 2","pages":"227-234"},"PeriodicalIF":0.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148347102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mild hyperbaric oxygen treatment may benefit peripheral microcirculation, parasympathetic activity, and metabolism but has not been studied extensively as a wound treatment modality. Due to the lower oxygen concentrations used in mild hyperbaric oxygen treatment, the risk of oxidative damage may be lower with this treatment than with traditional hyperbaric oxygenation. However, both mild and traditional hyperbaric oxygenation are associated with potentially life-threatening adverse events, including chamber explosion and/or fire. Careful adherence to safety standards may reduce the occurrence risk of such incidents, but compliance with those standards is not universally mandated and may vary among facilities.Discussion: Traditional and mild hyperbaric oxygen treatment differ in physiology and clinical uses. Both treatments are associated with significant risks, but adherence to safety standards may reduce the incidence of adverse events and optimize patient care.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"53 2","pages":"247-254"},"PeriodicalIF":0.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148347063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
