Effect of Noninvasive Positive Pressure Ventilation Combined with Nasal High Flow Humidified Oxygen Therapy on Elderly Patients with Respiratory Failure
Objective To explore the clinical effect of noninvasive positive pressure ventilation combined with nasal high flow humidified oxygen therapy in the treatment of respiratory failure in the elderly.Methods Fifty elderly patients with respiratory failure admitted to our hospital from June 2022 to June 2023 were selected as the study objects,and were divided into a control group and an observation group by random number table method,with 25 cases in each group.The control group was treated with non-invasive positive pressure ventilation,and the observation group was alternately treated with non-invasive positive pressure ventilation and nasal high flow humidifying oxygen therapy.The indexes of vital signs and blood gas were compared between the two groups at different time of treatment,and the incidence of complications were counted.Results After 2 and 3 days of treatment,the respiratory rate and heart rate of the observation group were lower than that of the control group,the oxygen partial pressure was higher than that of the control group,and the carbon dioxide fraction was lower than that of the control group,with statistical significance(P＜0.05).The incidence of complications in the observation group was 0.00%,which was lower than 24.00%in the control group,and the difference was statistically significant(P＜0.05).Conclusion Non-invasive positive pressure ventilation combined with nasal high-flow humidified oxygen therapy can improve vital signs and blood gas indexes in elderly patients with respiratory failure,and the risk of complications is low.
