This report details a case study of a non-smoking 33-year-old female nurse who developed occupational asthma as an Inside Attendant (IA) in a hyperbaric chamber. The report analyzes the nurse's medical history, working environment, and potential causes. After beginning work in the hyperbaric chamber, an IA experienced respiratory symptoms, including coughing, wheezing, and fatigue. Her symptoms improved during a break attending a hyperbaric nursing certification program but returned when she resumed work in the IA hyperbaric chamber. Spirometry confirmed airflow obstruction, and the IA was subsequently diagnosed with occupational asthma. As a result, the IA had to terminate their employment in the hyperbaric chamber. The literature review indicates that diving and hyperbaric exposure can negatively affect respiratory function, particularly in individuals susceptible to respiratory issues. We emphasize the necessity for further research on the effects of hyperbaric exposure on the respiratory system of IAs.

Hyperbaric oxygen therapy (HBOT) is a non-invasive method of O2 delivery that induces systemic hyperoxia. Hyperbaric chamber consists of a pressure vessel and a compressed breathing gas supply, which can regulate internal pressure. The chamber delivers 100% O2 to patients according to predetermined protocols and is monitored by trained personnel.

Background: The immunologic factors are the chief reason for recurrent pregnancy loss (RPL) and induction of maternal-fetal tolerance is the main treatment for this cause of RPL, but the effect of this method is uncertainly and needs multiple doses and/or interventions. The aim of this study was to investigate whether a single administration of transforming growth factor-β1 (TGF-β1) can improve the pregnancy outcomes of RPL mice and whether the improvement is cause by TGF-β1 driving the expression of immune tolerance molecule indoleamine 2,3-dioxygenase (IDO).
Materials And Methods: In this experimental study, 40 RPL model mice were equally divided into a control group, that received 0.

Middle ear barotrauma (MEBT) is the most common complication in providing hyperbaric oxygen therapy (HBO). This study explored the impact of altering the shape of the time-pressure curve with the aim of reducing the occurrence of MEBT and optimizing the HBO experience during the pressurization process. Four distinct mathematically derived protocols-Constant Pressure Difference (CPD), Constant Volume Difference (CVD), Constant Ratio (CR), and Inverted Constant Ratio (ICR)-were investigated using computer simulations on a simple ear model.
