We hypothesized the Zoll Z-vent® would deliver set tidal volumes incorrectly in volume control mode, but we could correct it using an algorithm. We used the Zoll Z-vent® in assist control mode in a Class A multiplace chamber and the Michigan test lung system. We identified the set tidal volumes on the ventilator that were necessary to achieve target tidal volumes at various depths. We graphed set tidal volume as a function of depth and performed linear regression modeling. From the regressions, we graphed the slope of each versus the target tidal volume and performed a second set of regressions. We generated an equation from our data to predict set tidal volumes. Set tidal volumes necessary to deliver target tidal volumes were directly proportional to depth in a linear manner. The slope of the regressions as a function of target tidal volume was also linearly proportional. The slope of the second set of regressions generated an equation that is used to predict set tidal volume for a given target tidal volume, PEEP, and gas. The Z-vent® can safely deliver mechanical ventilation under hyperbaric conditions with correction using our model. We use a spreadsheet to calculate set tidal volume for any given depth in clinical practice. We have internally validated this model on over 100 patients with multiple quality control measures in place.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 2","pages":"65-72"},"PeriodicalIF":0.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144862604","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}

We examined the data on 70 patients who suffered from SSNHL. The treatment was administered from 1 to 3 months after the onset of the hearing loss, i.e., after ineffective primary corticosteroid therapy. The monitored group was divided into three subgroups according to the degree of hearing impairment. Treatment success was assessed by using pre- and post-treatment audiograms. A statistically significant improvement in auditory threshold in all three frequency bands was observed in patients with severe hearing impairment of more than 60 dB, with mean auditory gains of 14.5 dB in low frequencies, 11.2 dB in middle (spoken speech) frequencies, and 13.2 dB in high frequencies. In this subgroup, 54.17 % of patients with severe hearing impairment experienced an improvement in hearing gain by 5 dB or more, 33.33 % by > 10 dB, and 25.00 % by > 20 dB. In patients with moderate and slight hearing impairments, the tendency to improve the hearing gain was not statistically significant. Based on our findings, we conclude that salvage HBO₂ treatment in patients with SSNHL is apparently most efficacious for individuals with severe hearing impairment. This finding is valuable for effective resource management in healthcare and public health.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 2","pages":"109-115"},"PeriodicalIF":0.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144862600","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}

We aimed to evaluate the use of hyperbaric oxygen (HBO₂) therapy in neurosurgery practice through cases followed in our clinic.Method: HBO₂ therapy was performed in 13 cases between 2019-2022 at our neurosurgery clinic. We retrospectively evaluated the cases in terms of the age at the time of treatment, the primary pathology, the number of sessions in which HBO2 therapy was performed, the sedimentation and CRP values and radiological images.Results: The mean age of the cases was 55.2 ± 16.4 years. Seven of the cases were female, and six of them were male. While 9 cases had infection secondary to spinal surgery performed for different indications, 1 case had wound site infection due to cranial surgery, 1 case had infection at the cranioplasty site, 1 case had infection in the area where a pain pacemaker was inserted, and 1 case had wound site infection after a carpal tunnel syndrome operation. The cases received an average of 30 sessions of HBO₂ therapy. While a significant decrease was seen in the sedimentation and CRP values, in all cases, a significant radiological improvement was seen in all the cases that were followed. In seven cases with surgical implants, there was no need for implant revision or removal.Conclusion: In our study, we observed that HBO₂ therapy is a good adjuvant treatment option to be used together with antibiotherapy in surgical site infections with and without implants, which are difficult to manage clinically.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 2","pages":"73-79"},"PeriodicalIF":0.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144862602","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}

From October 2013 to March 2020, the study analyzed 214 patients, including 62 treated with HBO₂ therapy. This study aims to describe the impact of HBO₂ therapy on improving tissue salvage and reducing amputation rates in severe frostbite-injured patients. The data suggested that patients undergoing HBO₂ therapy were more likely to receive thrombolytics and have larger areas of tissue impacted. They tended to be younger and had longer hospital stays. A significantly larger proportion of HBO₂ therapy-treated patients required surgical interventions, including amputation and debridement, compared to those not treated with HBO₂ therapy, reflecting the severity of their initial injury. Results indicate a complex relationship between HBO₂ therapy treatment and patient outcomes, suggesting that factors such as severity of injury, patient demographics, and thrombolytic therapy treatment significantly influence severe frostbite outcomes. This study contributes valuable insights to the limited literature on HBO₂ therapy in frostbite management and underscores the need for further controlled trials to ascertain its effectiveness conclusively.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 2","pages":"149-156"},"PeriodicalIF":0.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144862608","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}

Although the Japanese Society of Hyperbaric and Undersea Medicine officially approves paralytic ileus as an indication for hyperbaric oxygen therapy, the factors related to the prognosis of this therapy have not been determined. Accordingly, in this study, we evaluated factors that may be related to the prognosis of this therapy in patients with postoperative paralytic ileus. Patients in gastroenterological surgery, obstetrics and gynecology, and urology who underwent hyperbaric oxygen therapy for postoperative paralytic ileus from April 1, 2017, through March 31, 2022, were retrospectively evaluated. We set the primary outcome as the number of days to oral intake after the start of the therapy. First, we compared the differences in the number of days for various factors possibly related to its prognosis. Next, multivariate analysis using multiple linear regression analysis was performed. We evaluated 110 patients. Younger age, no prevalence of diabetes mellitus, the kind of surgery, no history of previous abdominal surgery, a shorter number of days from the onset to the start of therapy, and higher mean pressure of therapy had at least 1.5 fewer days of nothing by mouth. Multiple linear regression analysis revealed that only the mean pressure of therapy was a factor associated with the prognosis of hyperbaric oxygen therapy. Only the mean pressure of therapy is related to the prognosis of hyperbaric oxygen therapy. Further prospective studies adopting higher pressure therapy will be necessary to evaluate the efficacy of this treatment.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 2","pages":"93-99"},"PeriodicalIF":0.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144862601","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}
