Abstract：
BACKGROUND: Dyspnea associated with acute respiratory tract infections is a common cause of emergency admissions and can be distressing for children. This study aimed to evaluate the impact of a handheld fan intervention on physiological parameters in pediatric patients with dyspnea.
METHODS: A total of 59 children aged 2 to 12 years presenting to an emergency department for upper respiratory tract infection between March 2022 and March 2023 were assigned to the experimental group (n = 32) or control group (n = 27) by urn randomization. Both groups received the hospital\'s standard care, including 3 doses of inhaled bronchodilator at 20-minute intervals. The fan intervention consisted of parents applying a handheld electric fan to the child\'s face at a distance of 15 cm for 5 minutes after each inhaler treatment. Oxygen saturation, heart rate, and respiratory rate were recorded before treatment and after the 3 inhaler treatments.
RESULTS: There were no statistical differences in descriptive characteristics between the experimental and control groups (P > .05). Oxygen saturation values were significantly higher in the control group before treatment but showed greater increases in the intervention group after treatment (P < .001). The intervention group also exhibited greater reductions than the control group in both heart rate and respiratory rate after the third treatment than pretreatment values (P < .05).
CONCLUSIONS: The handheld fan intervention effectively supports inhaler treatment for children with dyspnea. Further studies are recommended to assess its impact across different age groups and clinical conditions.

摘要：
背景：与急性呼吸道感染相关的呼吸困难是急诊入院的常见原因，对儿童来说可能是痛苦的。本研究旨在评估手持式风扇干预对呼吸困难患儿生理参数的影响。
方法：将2022年3月至2023年3月期间因上呼吸道感染而到急诊科就诊的59名2至12岁儿童随机分为实验组（n=32）或对照组（n=27）。两组均接受医院的标准护理,包括3剂吸入支气管扩张剂，间隔20分钟。风扇干预包括父母在每次吸入器治疗后将手持电风扇以15厘米的距离应用于儿童的面部，持续5分钟。氧饱和度,心率,记录治疗前和3次吸入器治疗后的呼吸频率。
结果：实验组和对照组之间的描述性特征没有统计学差异（P>.05）。治疗前对照组血氧饱和度值明显高于治疗前，但治疗后干预组血氧饱和度值增加幅度更大(P<.001)。与治疗前相比，干预组的心率和呼吸频率在第三次治疗后的下降幅度也大于对照组（P<0.05）。
结论：手持风扇干预有效支持呼吸困难患儿的吸入器治疗。建议进一步研究以评估其对不同年龄段和临床状况的影响。
