Method: 42 children with acute asthma attacks were selected as the research subjects and randomly divided into a control group and an observation group. The control group was treated with air compression pump nebulization inhalation, while the observation group was treated with oxygen driven nebulization inhalation. Compare the total effective rate of two groups of children one week later, the difference in total effective rate between patients with hypoxemia and those without hypoxemia after treatment, the time for various clinical symptoms and signs (dyspnea, wheezing, cough, wheezing) to disappear, and the changes in maximum expiratory flow rate (PEF) before and after treatment. Result: After one week of treatment, the total effective rate of the observation group was 95.2%, significantly higher than the control group’s 61.9%, with a significant difference (P P P > 0.05. The disappearance time of various clinical symptoms and signs (dyspnea, wheezing, cough, wheezing) in the observation group was significantly shorter than that in the control group (P P < 0.05). Conclusion: Two different nebulization inhalation methods have achieved good therapeutic effects in treating acute asthma attacks in children, but the oxygen driven nebulization inhalation method is more effective, with more significant improvement in the patient’s condition and better prognosis.展开更多
