Comparison of Continuous Positive Airway Pressure Ventilation and Bi-level Positive Airway Pressure Ventilation in the Treatment of Patients with Acute Heart Failure with Decreased Ejection Fraction
Objective To investigate the therapeutic effects of continuous positive airway pressure(CPAP)and bi-level positive airway pressure ventilation(BiPAP)in patients with acute heart failure with reduced ejection fraction acute heart failure(AHF)patients with reduced ejection fraction.Methods Fifty-eight patients with AHF accompa-nied by decreased ejection fraction admitted to Xinxing County People's Hospital from June 2022 to December 2023 were non-randomly selected as the study subjects.They were divided into CPAP group and BiPAP group according to different treatment methods,with twenty-nine patients in each group.Compare the respiratory function indicators and hemodynamic indicators between two groups before and after treatment.Results After treatment,the arterial oxygen partial pressure in the BiPAP group was higher than that in the CPAP group[(93.65±7.48)mmHg vs(89.36±7.45)mmHg],the arterial carbon dioxide partial pressure was lower than that in the CPAP group[(35.06±4.01)mmHg vs(39.54±3.68)mmHg],the differences were statistically significant(t=2.188,4.433,both P<0.05).After treatment,both groups showed a significant decrease in end diastolic volume index and extravascular lung water index over time,the differences were statistically significant compared to before treatment(both P<0.05).However,there was no statisti-cally significant difference in the above indicators between the two groups(all P>0.05).Conclusion Compared with CPAP,BiPAP can improve the respiratory function of patients with acute heart failure,reduce the ejaculation fraction,and has no significant adverse effect on the hemodynamics of patients.
