Overview
Brief Summary
The study's primary aim is
- to compare the effects of two different ventilation modalities, non-invasive positive-pressure ventilation (NPPV) and high-flow nasal cannulae (HFNC), in the acute cardiogenic pulmonary edema (ACPE) setting, in terms of echocardiographic parameters of RV systolic and RV strain.
- to determine the differences of the two interventions on other hemodynamic parameters echocardiographically assessed.
- to assess the differences between the two interventions on physiological parameters, i.e., mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2), and on arterial blood gases (ABG) analysis parameters (i.e. relief of dyspnea and respiratory distress, patient comfort).
Enrolled patients will receive NPPV and HFNC oxygen therapy in a randomized, cross-over fashion, for 40 minutes each (time 0, T0 and time 1, T1), followed by clinical and echocardiographic evaluation

Outcomes
Primary Outcomes
RV systolic function: RV fractional area change (RVFAC), %
Time Frame: T2 (40 minutes after the second intervention has started)
RV fractional area change (RVFAC) is a parameter of radial RV function. It is calculated, in apical four chambers view, as the difference between end-diastolic and end-systolic RV area divided by the end-diastolic area and multiplied by 100. Normal value \> 35%.
RV systolic function: Tricuspid annular plane systolic excursion (TAPSE), mm
Time Frame: T2 (40 minutes after the second intervention has started)
Tricuspid annular plane systolic excursion (TAPSE) is a parameter of global RV function which describes apex-to-base shortening. Normal value \> 16 mm.
RV systolic function: RV Global Longitudinal strain (GLS), %
Time Frame: T2 (40 minutes after the second intervention has started)
RV Global Longitudinal strain (GLS) is an index of systolic performance of RV function. It evaluates the degree of myocardial deformation compared with its original length \[L0\] (%).
Secondary Outcomes
- Physiological parameter: oxygen saturation (SpO2), %(T2 (40 minutes after the second intervention has started))
- LV diastolic function parameter, i.e. LV average E/E' ratio(T2 (40 minutes after the second intervention has started))
- LV systolic function: Left Ventricle Ejection Fraction (LV EF), %(T2 (40 minutes after the second intervention has started))
- Inferior vena cava respiratory variations(T2 (40 minutes after the second intervention has started))
- Physiological parameter: mean arterial pressure (MAP), mmHg(T2 (40 minutes after the second intervention has started))
