NCT05989139

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

Outcome Measures

Primary Outcomes (9)

  • RV systolic function: Tricuspid annular plane systolic excursion (TAPSE), mm

    Tricuspid annular plane systolic excursion (TAPSE) is a parameter of global RV function which describes apex-to-base shortening. Normal value \> 16 mm.

    T0 (Patient's enrollment time)

  • RV systolic function: Tricuspid annular plane systolic excursion (TAPSE), mm

    Tricuspid annular plane systolic excursion (TAPSE) is a parameter of global RV function which describes apex-to-base shortening. Normal value \> 16 mm.

    T1 (40 minutes after the first intervention has started)

  • RV systolic function: Tricuspid annular plane systolic excursion (TAPSE), mm

    Tricuspid annular plane systolic excursion (TAPSE) is a parameter of global RV function which describes apex-to-base shortening. Normal value \> 16 mm.

    T2 (40 minutes after the second intervention has started)

  • RV systolic function: RV fractional area change (RVFAC), %

    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%.

    T0 (Patient's enrollment time)

  • RV systolic function: RV fractional area change (RVFAC), %

    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%.

Interventions

NPPV/HFNCPROCEDURE

Enrolled patients will receive NPPV and HFNC oxygen therapy in a randomized, cross-over fashion, for 40 minutes each. NPPV will be delivered through a full-face mask with a FiO2 starting at 100% and then titrated to achieve an SpO2 of 92-98%. Expiratory positive airway pressure (PEEP) will be firstly set to 5 cmH2O and then increased to a maximum of 15 cmH2O based on SpO2. Pressure support (PS) will be set to an initial value of 10 cmH2O and then increased if signs of respiratory distress persisted or worsened to a maximum value of 20 cmH2O. After 40 minutes, patient is shifted to HFNC ventilation support for 40 minutes. At the end of the protocol, the patient will receive the treatment that will be shown as more appropriate for the patient, according to the attending physician, who will be informed about the results of the study on the individual patient.

NPPV
HFNC/NPPVPROCEDURE

Enrolled patients will receive NPPV and HFNC oxygen therapy in a randomized, cross-over fashion, for 40 minutes each. HFNC oxygen therapy will start at a flow rate of 60 L/min and will be gradually decreased by 5 cmH2O at time if the patient experienced discomfort. FiO2 will be started at 100% and then titrated to maintain a peripheral oxygen saturation of 92%-98%. Active heating and humidification were provided using MR850, Fisher and Paykel, with a temperature chamber of 37°C. After 40 minutes, patient is shifted to NPPV ventilation support for 40 minutes At the end of the protocol, the patient will receive the treatment that will be shown as more appropriate for the patient, according to the attending physician, who will be informed about the results of the study on the individual patient.
