In this study, the Polaris Dawn mission crew evaluated optimal methods of CPR administration in the Dragon spacecraft during spaceflight as well as the impact of CPR tasks to the vehicle.Methods-CPR was simulated by compressing a CPR Adult Manikin Bellows Piston with Clicker against different surfaces of the vehicle. Crew members performed compressions at 3 different locations to select the optimal worksite. All 4 crew members then performed a 2-min round of compressions at the optimal worksite. Workload was measured using the Bedford workload and Borg rating of perceived exertion scales, where lower scores are desirable for both scales. Vehicle impacts were monitored with navigation and carbon dioxide sensors.Results-The outboard seat was selected as the optimal worksite. When performing a full 2 min of chest compressions at this location, average Bedford workload and Borg rating of perceived exertion scores among all 4 crew members were 4.75 and 16, respectively. All 4 crew members achieved the target-frequency range (mean, 1.8 Hz; range 1.7-1.9 Hz). Vehicle accelerations were observed in all axes, and cabin carbon dioxide increased to a peak level of >3.6 mm Hg, triggering a carbon dioxide caution limit.Conclusions-Outboard seat location provided the best ergonomics for administration of CPR on the Dragon spacecraft, although task performance had high difficulty ratings. CPR also was associated with elevated cabin carbon dioxide and vehicle accelerations, as measured by the navigation system.</p>","PeriodicalId":49360,"journal":{"name":"Wilderness & Environmental Medicine","volume":" ","pages":"53S-60S"},"PeriodicalIF":1.1,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144267796","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}

Toxic exposures from inadvertent release of vehicle or payload chemicals and materials used in the operations of spaceflight are unique among them. There is a need for identification and development of clinical protocols for the management of toxic exposures before, during, and after spaceflight, particularly for acute exposures, because these events are likely to occur in austere environments with limited resources. The need for publicly available protocols is gaining importance as commercial spaceflight operations advance, and future spaceflight missions will require independence from Earth. This paper reviews the publicly available literature on toxic exposures in spaceflight to inform the development of relevant clinical practice guidelines. We performed a focused literature review and identified significant aerospace toxicologic incidents, including fatalities, injuries, and near-miss events. Sources included NASA-published literature, NASA safety reviews, published case reports, and published review articles. Searches were performed using the NASA Technical Reports Server, Google Scholar, and PubMed, and we included all cases involving exposure or potential exposure to an agent that could cause acute toxicity in spaceflight missions. Thirty-four cases were identified involving agents that can cause acute toxic effects. The two most common agents identified in acute toxicologic exposures in spaceflight operations were hydrazine and ammonia.

Although biomedical approaches commonly appear in the literature, considering psychological and social factors alongside physiologic health offers a more holistic approach to astronaut care. Integrating the biopsychosocial (BPS) framework into medical planning addresses complex spaceflight challenges and aids in developing mitigation strategies. This review examined health risks associated with long-duration spaceflight within a BPS framework. Sources included governmental space agencies, academic textbooks, and relevant publications from multiple databases. Considering the National Aeronautics and Space Administration's Human Research Program's 5 main hazards, a conceptual model was developed to highlight the multifactorial BPS effects of spaceflight. In space, astronauts face unique environments and biological adaptations, including fluid shift, plasma volume loss, bone density loss, and muscle atrophy. Noise and the absence of natural light disrupt circadian rhythms, causing sleep disturbances and fatigue, which affect physical and mental health. Studies on crews in isolated and confined extreme environments reveal psychosocial challenges, including impaired mood and cognition, interpersonal tension, and miscommunication. International collaboration in spaceflight introduces differences in communication, problem solving, and social customs due to diverse cultural backgrounds. Upcoming long-distance missions likely will amplify these challenges. This review emphasizes BPS health considerations in long-duration spaceflight.

This study investigated how varying oxygen exposure durations affect the thermal performance of these blankets to guide their optimal use in search and rescue scenarios.MethodsIn room-temperature conditions, a full-body manikin was wrapped in a standardized hypothermia model, including a chemical heat blanket, and evaluated under 3 conditions: 1) no shaking, 2) shaking for 2 min, and 3) shaking for 15 min before wrapping. Thermometers were placed inside the heating panel pockets and secured in place with tape to ensure consistent measurements. Temperature data were collected over 6 h, and each scenario was performed 4 times.ResultsBlankets shaken for 2 min achieved higher initial temperatures than those not shaken, with a significant difference sustained for 88 min.

It has been observed that climbers sometimes apply magnesium carbonate chalk to small wounds to stop bleeding, suggesting that climbing chalk may exhibit hemostatic properties useful for small cuts and scrapes. This study aimed to investigate and compare the effects of different types of climbing chalk on prothrombin time (PT) and activated partial thromboplastin time (aPTT).MethodsThree types of climbing chalk were randomly selected for comparative analysis of hemostatic properties, with talcum powder used as a negative control. PT and aPTT testing were conducted on normal plasma samples containing varying concentrations of climbing chalk (from 0.125 mg/mL to 4 mg/mL). Statistical analyses of the results were performed using two-tailed t-tests, Welch's analysis of variance (ANOVA), and Games-Howell post-hoc analysis.ResultsResults indicated that climbing chalk had no significant effect on PT but did significantly reduce aPTT compared to the negative control. Additional analyses revealed significant differences in aPTT results between different types of chalk and between higher and lower concentrations of chalk.ConclusionsMagnesium carbonate-based climbing chalks appear to have a procoagulant effect on hemostasis, likely by affecting the intrinsic pathway of the coagulation cascade.
