Objective To analyze and evaluate the therapeutic effect of health education on lung function of infants with bronchiolitis . Methods Totally 120 infants with bronchiolitis were randomly divided into control group and observation group , with 60 cases in each group.The control group received routine care , while the observation group was given health education guidance on the basis of the control group.Indicators change of lung function , parents ’ related knowledge and compliance behavior were analyzed in order to evaluate the therapeutic effect.Results In observation group VT was 6.41 ±1.15 mL, TPTEF/TE was 17.92 ±6.79, and VPEF/VE was 21.98 ± 4.12.They were higher than those in the control group (5.79 ±1.51 mL, 15.31 ±6.69, and 20.29 ±4.18, respectively) (t value was 2.53, 2.12 and 2.23, respectively, all P<0.05).The respiratory rate (RR) of the observation group was significantly lower than that of the control group (38.12 ±9.28 min vs 41.97 ±10.11 min) (t=2.17, P<0.05).It indicated that airway obstruction was milder and the illness was milder in the observation group after intervention .The awareness rate of knowledge on disease , rate of compliance behavior, understanding rate of spirometry and overall satisfactory rate of nursing quality in the observation group were 96.67%, 93.33%, 91.67%and 96.67%, respectively.And they were 58.33%, 65.00%, 53.33% and 78.33%, respectively in the control group .The values of the observation group were significantly higher than the control group (χ2 value was 25.28, 14.60, 22.11 and 9.22, respectively, all P <0.05).Conclusion Health education guidance improves the knowledge of parents on disease , understanding of spirometry, compliance behavior and overall satisfaction , and improves the lung function of the cases .The treatment has played a crucial role.%目的：分析并评价健康教育对毛细支气管炎婴幼儿肺功能治疗效果的影响。方法将选取的120例婴幼儿毛细支气管炎患儿随机分为对照组和观察组各60例，对照组给予常规护理，观察组在对照组的基础上给予健康教育指导，分析患儿肺功能各项指标变化、相关知识掌握和遵医行为等情况，以评价其治疗效果。结果观察组患儿肺功能测定各项指标值中，潮气量（VT）为（6．41±1．15）mL、达峰时间比（TPTEF/TE）为（17．92±6．79）、达峰容积比（VPEF/VE）为（21．98±4．12），均高于对照组患儿肺功能测定的各项指标VT（5．79±1．51）mL、TPTEF/TE（15．31±6．69）、VPEF/VE（20．29±4．18）；而观察组患儿呼吸频率（RR）为（38．12±9．28）min，低于对照组患儿RR（41．97±10．11）min，组间经比较差异均具有统计学意义（t值分别为2．53、2．12、2．23和2．17，均P＜0．05），说明观察组患儿干预后气道阻塞轻，病情较轻。观察组患儿家长对疾病知识掌握率为96．67％，遵医行为率为93．33％，肺功能测定了解率91．67％，护理质量总满意率为96．67％；对照组各项调查项目分别为58．33％、65．00％、53．33％、78．33％，观察组高于对照组，组间经比较差异均具有统计学意义（χ2值分别为25．28、14．60、22．11和9．22，均P＜0．05）。结论健康教育指导有效提高了患儿家长对疾病知识的掌握、肺功能测定了解、遵医行为和护理质量总满意度，改善患儿肺功能，对治疗起到至关重要的作用。
