Objective: The experiment will explore the clinical efficacy of non-invasive ventilator in the treatment of heart failure complicated with respiratory failure in ICU ward. Methods: A total of 60 patients with heart failure combined with respiratory failure were screened out in the study, and they were all admitted to our hospital for treatment from March 2020 to May 2021, and were grouped according to the principle of parallel control. The patients in the control group were treated with conventional drugs and low-flow continuous oxygen inhalation therapy, and the patients in the observation group were treated with conventional drugs and non-invasive positive pressure ventilation, and the treatment results were compared. Results: From the data of arterial blood gas results after treatment, the Pa02, PaC02 and PH values of the observation group were (8.1±2.5) mmHg, (5.4±0.7) mmHg, (7.5±0.4), respectively, and the control group were (7.8±2.1) mmHg, (5.9±0.8) mmHg, (7.4±0.3), the observation group was better than the control group, and the comparison was statistically significant (P<0.05). The heart rate and respiratory rate of the two groups of patients after treatment were compared. The heart rate and respiratory rate of the observation group were (62.1±8.9) times/min, (18.8±1.2) times/min, and the control group were (78.4±8.7) times/min, respectively. (26.3±1.6) times/min, the observation group was significantly lower than the control group, and the comparison was statistically significant (P<0.05). At the same time, in the investigation of the treatment efficacy, the total treatment efficacy rate of the observation group was 96.6%, which was significantly better than that of the control group, which was 73.3%, and the difference was statistically significant. Conclusion: The use of non-invasive ventilator therapy for patients with heart failure combined with respiratory failure in ICU ward has a significant therapeutic effect, which can improve the total effective rate of treatment. We should continue to adhere to this strategy and develop through inheritance and reference.
