  • Background: The purpose of this study was to investigate the effects of HBOT (hyperbaric oxygen therapy) on the pain, ROM (range of motion) and muscle fatigue recovery of DOMS (delayed onset muscle soreness). Design: Randomized Controlled Trial. Methods: Twenty-six subjects who are student in their 20s at a university participated in this study, these subjects were assigned into two groups, a control group (n=12) and an experiment group (n=14). The subjects in experimental group were intervened by HBOT (40 minutes, 1.3 ATA), while ones on control group weren't by any intervention after induced DOMS. Results: First, in the comparison of VAS (visual analog scale), there were significant variations with the period (p<0.001), interaction of period (p<0.05) and group (p<0.05). In the comparison of PPT (pressure pain threshold), there were significant variations with the period (p<0.001) and interaction of period (p<0.05). Second, in the comparison of ROM, there were significant variations with the period (p<0.001), interaction of period (p<0.001) and group (p<0.01). Third, in the comparison of CK (creatine kinase) and LDH (lactate dehydrogenase), there no signigicant variations with all measure variables. Conclusion: The above results indicated that HBOT were effective to decrease the pain and improve the ROM in DOMS. Also the statistical significant variations of blood factors of muscle fatigue were not found in this.

  • There is a delicate balance between too little and too much supplemental oxygen exposure in premature infants. Since underuse and overuse of supplemental oxygen can harm premature infants, oxygen saturation levels must be monitored and kept at less than 95% to prevent reactive oxygen species-related diseases, such as retinopathy of prematurity and bronchopulmonary dysplasia. At the same time, desaturation below 80 to 85% must be avoided to prevent adverse consequences, such as cerebral palsy. It is still unclear what range of oxygen saturation is appropriate for premature infants; however, until the results of further studies are available, a reasonable target for pulse oxygen saturation ($SpO_2$) is 90 to 93% with an intermittent review of the correlation between $SpO_2$ and the partial pressure of arterial oxygen tension ($PaO_2$). Because optimal oxygenation depends on individuals at the bedside making ongoing adjustments, each unit must define an optimal target range and set alarm limits according to their own equipment or conditions. All staff must be aware of these values and adjust the concentration of supplemental oxygen frequently.

  • Malignant tumors of the head and neck frequently require treatment with both radiotherapy and surgery. Reconstruction of the defect in previously irradiated field is a challenge to surgeon, who must produce both a functional and an esthetic result. Hyperbaric oxygen therapy(HBO) has been used in an attempt to reduce the deleterious effects of radiation. But the issue of whether prior irradiation and HBO of the recipient site of a free flap affects the result of reconstruction continues to generate controversy. So, the effects of irradiation and hypergbaric oxygen therapy on microvascular anastomosis was evaluated in an experimental study in femoral vessels of rats. The experimental groups were divided into 3 groups, contorol group, irradiation group, and irradiation and HBO group. Preoperative irradiation was delivered in the left groin field with single dose corresponding 2,000cGy and total 48 hours of HBO was given 100% oxygen at 2.4 atmosphere for 4 weeks. The femoral vessels of 60 rats were anastomosed after irradiation and HBO treatment. Three days, 1 week, 2 weeks and 4 weeks after surgery, the femoral vessels were evaluated for patency and histopathologic changes. There was no notable effect of irradiation on patency of femoral vessels in rats and the radiation effects were obvious on histological examination which showed the sloughing of the endothelial cells, subintimal hyperplasia and fibrosis on the media and adventitia of femoral arteries. The histologic changes of the femoral veins were mild and not typical. But the effects of hyperbaric oxygen therapy after irradiation was seen not marked difference in irradiation group.

  • Purpose: The aim of this study was to characterize the healing in the grafted calvarial defects of rats after adjunctive hyperbaric oxygen therapy. Methods: Twenty-eight male Sprague-Dawley rats (body weight, 250-300 g) were randomly divided into two treatment groups: with hyperbaric oxygen therapy (HBO; n=14) and without HBO (NHBO; n=14). Each group was further subdivided according to the bone substitute applied: biphasic calcium phosphate (BCP; n=7) and surface-modified BCP (mBCP; n=7). The mBCP comprised BCP coated with Escherichia-coli-derived recombinant human bone morphogenetic protein-2 (ErhBMP-2) and epigallocatechin-3-gallate (EGCG). Two symmetrical circular defects (6-mm diameter) were created in the right and left parietal bones of each animal. One defect was assigned as a control defect and received no bone substitute, while the other defect was filled with either BCP or mBCP. The animals were allowed to heal for 4 weeks, during which those in the HBO group underwent 5 sessions of HBO. At 4 weeks, the animals were sacrificed, and the defects were harvested for histologic and histomorphometric analysis. Results: Well-maintained space was found in the grafted groups. Woven bone connected to and away from the defect margin was formed. More angiogenesis was found with HBO and EGCG/BMP-2 (P<0.05). None of the defects achieved complete defect closure. Increased new bone formation with HBO or EGCG/BMP-2 was evident in histologic evaluation, but it did not reach statistical significance in histometric analysis. A synergic effect between HBO and EGCG/BMP-2 was not found. Conclusions: Within the limitations of this study, the present findings indicate that adjunctive HBO and EGCG/BMP-2 could be beneficial for new bone formation in rat calvarial defects.

  • Purpose: The aim of this study was to develop a simulation-based High Flow Nasal Cannula Oxygen Therapy training program based on NLN/ISF to identify the effect on knowledge, clinical performance, and educational satisfaction compared to a group who had traditional High Flow Nasal Cannula Oxygen Therapy training after applying it to clinical nurses. Methods: 31 experimental groups and 33 control groups were conducted from August 2019 to September 2019 for inexperienced nurses over 4 months to 5 years with no experience using high-flow oxygen therapy. Educational programs were developed in scenarios according to Airvo2 and Optiflow, such as facilitator, participant, educational condition, design, characteristics, and educational outcomes. The education application was conducted in advanced for knowledge and clinical performance ability after watching therapy video. Since then, a total of 90 minutes have been conducted for respiratory failure theory training, airvo2 and optiflow simulation training, and debriefing. After applying the education, the medical institution measured nurses' knowledge, clinical performance, and education satisfaction. Data were analyzed using descriptive statistics, with the SPSS/WIN 22.0 program. Results: Both knowledge and educational satisfaction were higher in the experimental group than in the control group (t=-14.09, p<.001), (t=-12.99, p<.001). The clinical performance for both use of Optiflow and Airvo2 were higher in the experimental group than in the control group (t=-11.39, p<.001), (t=-11.38, p<.001). Conclusion: Results showed that the simulation-based High Flow Nasal Cannula Oxygen Therapy training was effective with the experimental group having increased scores for every area of this study.

  • Background: The coronavirus disease (COVID-19) can manifest in a range of symptoms, including both asymptomatic systems which appear nearly non-existent to the patient, all the way to the development of acute respiratory distress syndrome (ARDS). Specifically, COVID-19-associated pneumonia develops into ARDS due to the rapid progression of hypoxia, and although arterial blood gas analysis can assist in halting this deterioration, the current environment provided by the COVID-19 pandemic, which has led to an overall lack of medical resources or equipment, has made it difficult to administer such tests in a widespread manner. As a result, this study was conducted in order to determine whether the levels of oxygen saturation (SpO2) and the fraction of inhaled oxygen (FiO2) (SF ratio) can also serve as predictors of ARDS and the patient's risk of mortality. Methods: This was a retrospective cohort study conducted from February 2020 to Mary 2020, with the study's subjects consisting of COVID-19 pneumonia patients who had reached a state of deterioration that required the use of oxygen therapy. Of the 100 COVID-19 pneumonia cases, we compared 59 pneumonia patients who required oxygen therapy, divided into ARDS and non-ARDS pneumonia patients who required oxygen, and then investigated the different factors which affected their mortality. Results: At the time of admission, the ratios of SpO2, FiO2, and SF for the ARDS group differed significantly from those of the non-ARDS pneumonia support group who required oxygen (p<0.001). With respect to the predicting of the occurrence of ARDS, the SF ratio on admission and the SF ratio at exacerbation had an area under the curve which measured to be around 85.7% and 88.8% (p<0.001). Multivariate Cox regression analysis identified that the SF ratio at exacerbation (hazard ratio [HR], 0.916; 95% confidence interval [CI], 0.846-0.991; p=0.029) and National Early Warning Score (NEWS) (HR, 1.277; 95% CI, 1.010-1.615; p=0.041) were significant predictors of mortality. Conclusion: The SF ratio on admission and the SF ratio at exacerbation were strong predictors of the occurrence of ARDS, and the SF ratio at exacerbation and NEWS held a significant effect on mortality.
