ABSTRACT
Objective:To study the application of scenario simulation teaching combined with modular training in nursing education of medical rescue in manned space flight.Methods:Twenty nurses from the medical rescue team of Strategic Support Force Characteristic Medical Center were selected as the research objects. The research objects were randomly divided into the scenario simulation combined with practical training group (practical training group, n=10) and traditional teaching group (control group, n=10). Scenario simulation teaching combined with modular training and traditional teaching were used to carry out nursing training. After the training, theoretical assessment, operation assessment and satisfaction survey were organized. Results:The scenario simulation teaching combined with modular training group was significantly better than the traditional training group in theory assessment, operation assessment and satisfaction survey of nursing staff (all P<0.05). Conclusions:Scenario simulation teaching combined with modular training has obvious teaching effect, which can improve the ability and quality of nursing staff, and help to complete the manned space medical rescue mission efficiently.
ABSTRACT
Manned space environmental simulation technology is a very important branch of Space Medico-Engineering.After introducing the principles and methods of manned space environmental simulation technology,the current development of artificial atmosphere environment,space environment,dynamic environment,weightlessness environment and products of manned space environmental simulation technology were reviewed.
ABSTRACT
Objective To explore a space craft precooling temperature at which excessive thermal stress on the crew member could be prevented or reduced in an overheated launch or reentry module. Method Five young male volunteers wearing a space suit participated in 25 tests at sea level.The space suit was either ventilated in a volume air flow rate of 100 L/min (STPD) with ambient air at temperatures (Ta) of 15℃,10℃,and 5℃,respectively,or not ventilated. Rectal (Tr),mean skin (Tsk) and mean body (Tb) temperatures were measured. Result At Ta 15℃,Tr decreased without significance (from 37.0±0.2℃to 36.7±0.3℃) in 120-min tests,whereas Tsk and Tb decreased significantly,and subjects had local cold strain whether the space suit was ventilated or not; while at Ta 10℃,Tr decreased from 37.0±0.3℃ to 36.3±0.3℃(P<0.05),subjects had a whole body cold strain,and both Tsk and Tb dropped continuously and significantly. Conclusion Ambient temperature 15℃,at which the thermal comfort states of crew was not significantly degraded,was acceptable after precooling in a space craft.
