Echocardiographic analysis. a Ejection fraction (EF) and ratio of pulmonary artery acceleration time (PAT) to pulmonary artery ejection time (PET). The PAT/PET ratio was used as an indirect index of pulmonary arterial hypertension. b Representative images of pulmonary blood flow at T4. Note the spiculated pattern of the pulmonary artery flow curve in PCV and bell-shaped curve in PSV. PCV pressure-controlled ventilation, PSV pressure support ventilation. Symbols are means ± SD of six animals. *p < 0.05, **p < 0.01, ***p < 0.001
