Objective In this study, patients with chronic obstructive pulmonary disease were treated with high-flow heating and humidified oxygen inhalation therapy, and the therapeutic effect of this method was analyzed. Methods A total of 200 patients with COPD combined with respiratory failure were selected and randomly divided into two groups with 100 cases in each group. Both groups were treated with conventional anti-infection, phlegm reduction, inhibition of airway inflammation, correction of electrolyte imbalance and other related treatments. The observation group was treated with a high-flow heating and humidified oxygen inhalation device under the premise of conventional treatment, and the patients in the control group were treated with continuous low-flow nasal cannula oxygen inhalation under the premise of conventional treatment. Clinical symptoms, heart rate, pH, respiratory rate, and adverse effects. Results After treatment, the heart rate, respiratory rate and PaCO2 of the two groups of patients were significantly decreased compared with those before treatment, while PaO2 and SaO2 were significantly increased compared with those before treatment. The pH of the control group did not improve significantly before and after treatment, while the pH of the observation group increased significantly after treatment. Significant improvement before and after. After treatment, the respiratory rate of patients in the observation group decreased and was higher than that in the control group. The decrease degree of PaCO2 in the control group was higher. There was no significant difference in pH, heart rate, PaO2 and SaO2 between the two groups after treatment. After treatment, there were 24 cases of sputum dilution and cough in the observation group, and 13 cases in the control group with sputum dilution and easy coughing after treatment. Compared with the control group, the observation group was significantly higher, and the nose in the control group was dry and uncomfortable There are 9 patients who need non-invasive ventilation due to the high partial pressure of carbon dioxide, while 13 patients in the observation group feel that the nasal air flow is larger. There are 2 cases. Conclusion For COPD patients with respiratory failure, the high-flow heating and humidifying oxygen inhalation therapy has a good therapeutic effect. It can relieve the patients breathing frequency and improve the symptoms of sputum dilution to a certain extent. Close monitoring of the patient is required during treatment. Qi, blood and other clinical symptoms, take mechanical ventilation if necessary.
