机械模拟肺在ICU新护士规范化培训中机械通气教学的应用效果评价

目的:探讨机械模拟肺在重症医学科新护士规范化培训中机械通气教学的应用效果,提高护士在机械通气方面的理论与技能水平。方法:选择2019年8月至2020年7月我院护理学本科专业且参加规范化培训的60名护士,试验组采用机械模拟肺进行机械通气理论与实践教学,对照组利用普通模拟肺进行传统讲授式机械通气教学,培训结束后实施理论及实践考核,通过发放问卷,进行教学效果评价。结果:试验组理论考核简答题成绩及总分均高于对照组;试验组实践考核成绩在手法肺复张、测定阻力和顺应性、机械通气波形识别方面均优于对照组,差异均有统计学意义(P<0.05)。结论:机械模拟肺应用在重症医学科新护士规范化培训机械通气教学效果显著,提高了护士在机械通气方面的理论与技能水平,提升了教学满意度,值得推广应用。

Study on air flow dynamic characteristic of mechanical ventilation of a lung simulator

As an important life support treatment, mechanical ventilation is usually adopted in clinics. With the development of the res-piratory diagnostic and treatment technologies, air flow dynamics of mechanical ventilation is usually referenced in the evaluation of pulmonary status and assessment of respiratory therapy. In order to improve the ventilation efficiency and provide a reference for pulmonary diagnostics, in this paper, a new mathematical model of mechanical ventilation system was set up. Furthermore, a prototype mechanical ventilation system for an artificial simulating lung was designed and experimentally studied. Lastly, in order to improve the ventilation efficiency and provide a reference for pulmonary diagnostics, the air flow dynamics of the mechanical ventilation system was illustrated through simulation and experimental studies. The study can be helpful to the optimization of the mechanical ventilation system.
