| Objective: To explore the effect of noninvasive ventilator-assisted ventilation on acute heart failure.Methods: a total of 61 patients with acute heart failure admitted to the First Affiliated Hospital of Xinjiang Medical University from October 2017 to December2019 were studied and analyzed.According to the different treatment methods,they were divided into two groups: experimental group(29 cases)and control group(32 cases).The control group was treated with conventional medicine and high flow continuous oxygen inhalation,while the experimental group was treated with conventional medicine and non-invasive ventilator assisted ventilation.After 2 hours of treatment,the clinical effective rate and the changes of PaO2,PaCO2,pH,heart rate and blood pressure were monitored.The changes of left ventricular ejection fraction,left ventricular end systolic diameter,left ventricular end diastolic diameter and BNP were monitored 24 hours after treatment.Results: the total effective rate of clinical treatment in the experimental group(90.7%)was higher than that in the control group(65.6%).The difference between the two groups was statistically significant(P < 0.05).After treatment,the indexes of PaO2,PaCO2,pH,left ventricular ejection fraction,left ventricular end systolic diameter and left ventricular end diastolic diameter were significantly improved in the selected patients.The improvement in the experimental group was more significant,and the difference was statistically significant(P < 0.05).Conclusion:non-invasive ventilator-assisted ventilation can significantly increase PaO2,relieve PaCO2 and make pH tend to normal level in patients with acute heart failure.Heart rate,blood pressure and respiratory rate were improved.The ejection function of heart was enhanced.So as to effectively alleviate the symptoms of patients and improve the life treatment of patients. |
