Abstract：Objective To explore the efficacy of high-flow humidified oxygen therapy compared with conventional oxygen therapy on children with bronchopneumonia.Methods A total of 68 children with bronchopneumonia admitted from January 2022 to January 2025 were selected and divided into the high-flow group(34 cases)and the conventional group(34 cases)according to the oxygen therapy methods.The high-flow group was cared for with high-flow humidified oxygen therapy,while the conventional group was cared for with traditional oxygen therapy.The arterial blood gas analysis indicators,the improvement time of clinical symptoms,respiratory function parameters and the occurrence of complications were compared between the two groups.Results After treatment,the PaO2[(89.42±5.31)mmHg]and SaO2[(96.82±2.14)%]in the high-flow group were both higher than those in the conventional group[PaO2(81.36±4.87)mmHg and SaO2(93.45±2.68)%].PaCO2[(38.24±3.16)mmHg]was lower than that of the conventional group[(42.37±3.54)mmHg](P<0.05).The cough relief time[(3.82±0.94)d],the disappearance time of pulmonary rales[(4.16±1.02)d],and the hospital stay[(6.74±1.38)d]in the high-flow group were all shorter than those in the conventional group(P<0.05).The improvement in respiratory distress score was more significant in the high-flow group,and the incidence of complications was lower(P<0.05).Conclusion High-flow humidified oxygen therapy can effectively improve the oxygenation status of children with bronchopneumonia,accelerate the relief of clinical symptoms,and reduce the occurrence of complications,and its clinical application value is superior to that of conventional oxygen therapy.
