目的探讨肺功能检查视听教材对肺功能检查的作用,为进一步推广普及肺功能检查和调整我国肺功能临床应用策略提供依据。方法选择肺功能检查受试者525例,随机分为对照组320例和暴露组205例。对照组进行常规的肺功能操作教育,暴露组采用播放视听教材及常规肺功能操作教育,从而比较两组受试者用力肺活量检查完成的质量。结果两组受试者年龄、性别、肺功能严重程度无统计学意义(P>0.05),具有可比性。对照组和暴露组在用力肺活量中第一次内就能完成达标的F-V曲线分别为21.9%和37.6%(=-4.195,P<0.01);第一次内完成达标V-T曲线分别为23.0%和36.1%(=-4.195,P<0.01);第一次内呼出达标外推容积分别为22.2%和31.2%(=-2.675,P<0.01);检查总次数控制在5次以内的达标率分别为53.6%和68.3%(=-3.733,P<0.01);测试时间控制在5分钟内完成的达标率分别为27.2%和43.4%(=-4.334,P<0.01)。结论肺功能测试需要受试者良好的配合和指导人员的专业操作及指导,肺功能检查全国卫生试听教材有助于提高受试者在第一次内完成达标的用力肺活量测试,并减少了测试时间和总检测次数,有效提高了受试者配合程度及检查效率。
Objective To investigate the effect of audio-visual teaching materials of pulmonary function tests on pulmonary function tests, and to provide evidence for further popularizing universal pulmonary function tests and adjusting the clinical application strategies of lung function in our country. Methods 525 subjects with pulmonary function tests were randomly divided into control group (320 cases) and exposure group (205 cases). The control group was given routine pulmonary function education. The exposed group was given audiovisual teaching materials and routine pulmonary function education so as to compare the quality of the forced vital capacity examination performed by both groups. Results There was no significant difference in age, sex and pulmonary function between the two groups (P> 0.05). The FV curves of the control group and the exposure group that were able to achieve compliance within the first time of forced vital capacity were 21.9% and 37.6%, respectively (= - 4.195, P <0.01). The first-order compliance VT curves were 23.0% 36.1% (= - 4.195, P <0.01). The first extraoral volume was 22.2% and 31.2% respectively (= -2.675, P <0.01) Were 53.6% and 68.3% respectively (= - 3.733, P <0.01). The compliance rate of test time control within 5 minutes was 27.2% and 43.4% (= - 4.334, P <0.01) respectively. Conclusion Pulmonary function tests need good cooperation of the subjects and professional guidance and guidance of the instructor. The national health audition teaching materials of pulmonary function tests can help to improve the subjects’ forced vital capacity test in the first time and reduce the test Time and the total number of tests, effectively improve the degree of cooperation with the subjects and check the efficiency.
