Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Right ventricular area fractional change (RV FAC)
Time Frame: RV FAC monitoring was performed 1 day after APRV mechanical ventilation
Right ventricular area fractional change (RV FAC)is a simple and repeatable ultrasound method for evaluating RV function. Methods: The RV end-diastolic area (RVEDA) and RV end-systolic area (RVESA) were measured on the apical four-chamber section by two-dimensional ultrasound. RV FAC=(RVEDA- RVESA)/RVEDA*100%.
RV FAC monitoring was performed 1 day after APRV mechanical ventilation
Tricuspid annular systolic displacement(TAPSE)
Time Frame: TAPSE monitoring was performed 1 day after APRV mechanical ventilation
TAPSE:TAPSE is one of the most effective ultrasound methods for evaluating right ventricular function.Measurement method: TAPSE was measured on the four-chamber section of the apex of the heart by M-mode ultrasound. the sampling line was placed at the side wall of the tricuspid valve ring, parallel to the free wall of the right ventricle as far as possible, and the displacement of the tricuspid valve ring was measured from the end of diastole to the end of systole.
TAPSE monitoring was performed 1 day after APRV mechanical ventilation

Time Frame: TS' monitoring was performed 1 day after APRV mechanical ventilation
TS' is an objective and accurate ultrasound technique for evaluating right ventricular function.Measurement method:The sample volume was applied to the free wall of the RV and the peak velocity of tricuspid annulus motion was measured in the four-chamber section of the apex by tissue doppler imaging (TDI).
TS' monitoring was performed 1 day after APRV mechanical ventilation

Time Frame: RVEDA/LVEDA monitoring was performed 1 day after APRV mechanical ventilation
RVEDA/LVEDA a simple and repeatable ultrasound method for evaluating dynamics changes of RV function.Methods: The RV end-diastolic area (RVEDA) and left ventricular(LV) end-systolic area (LVEDA) were measured on the apical four-chamber section by two-dimensional ultrasound.
RVEDA/LVEDA monitoring was performed 1 day after APRV mechanical ventilation
Pulmonary circulatory resistance (PVR)
Time Frame: PVR monitoring was performed 1 day after APRV mechanical ventilation
Increased PVR can lead to deterioration of RV function.Pulse Doppler imaging (PWD) was used to obtain the pulmonary artery flow spectrum from the pulmonic valve on the short axial section of the parasternal great vessels.
