To explore the role of bedside cardiopulmonary ultrasound in the evaluation of non-invasive positive pressure ventilation (NPPV) in patients with cardiaogenic pulmonary edema in emergency department.


The clinical data and characteristics of bedside rapid cardiopulmonary ultrasound in patients withcardiaogenic pulmonary edema treated with NPPV in the emergency department were retrospectively analyzed. The following ultrasound parameters, including lung ultrasound score, the ratio of lung consolidation, diameter of inferior vena cava, left ventricular ejection fraction (LVEF), the mitral annular systolic displacement (MAPSE) and tricuspid annular systolic displacement (TAPSE), the peak Doppler velocities of the early diastolic mitral (E), the tissue velocity imaging of left ventricular and right ventricular (Sm), the tissue Doppler of the early diastolic velocity of the mitral annulus (e’), the average E/e’ ratio of left ventricular, systolic pulmonary artery pressure (SPAP) and the ratio of atrial fibrillation,, were determined. All of the parameters combined with clinical parameters were compared between the non-invasive ventilation success group and non-invasive ventilation failure group. Univariate and multivariate logistic regression analysis were used to screen out the risk factors by taking the failure of NPPV treatment as the dependent variable. The area under the receiver operating characteristic (ROC) curve was used to analyze the predictive value of the indicators above.


A total of 66 patients, included 44 (66.%) of NPPV success and 22 (33.3%) of NPPV failure revealed by bedside cardiopulmonary ultrasound. In comparison with the NPPV success group, the lung ultrasound score, ratio of lung consolidation, E/e’ of LV , SPAP, the ratio of right ventricular dysfunction, the ratio of atrial fibrillation and the level of Ccr were significantly evaluated, but the Sm of right ventricular and PaO2/FiO2 were significantly lower in the NPPV failure group (all P< 0.05). There were no differences in LVEF, MAPSE, TPASE, diameter of inferior vena cava and the Sm of left ventricular between groups (all P> 0.05). Multivariate logistic regression analysis showed that lung ultrasound score, E/e’ and SPAP were independent predictors of NPPV failure in patients with cardiaogenic pulmonary edema. The AUCs of lung ultrasound score, E/e’ of LV and SPAP for predicting NPPV failure was 0.802, 0.783 and 0.852, respectively. .


The lung ultrasound score, right ventricular diastolic function and SPAP evaluated by bedside cardiopulmonary ultrasound could provide predictive values for the non-invasive positive ventilation failure in patients with cardiaogenic pulmonary edema.
