Comparison with pulmonary artery occlusion pressure (PAOP) levels considering a cutoff point at 18 mmHg: on the left, the group of patients showing A-pattern at lung ultrasound and the subgroup showing A-pattern combined with normal left ventricular (LV) ejection fraction estimated at focused cardiac ultrasound; on the right, the group showing B-pattern and the subgroup showing B-pattern combined with reduced LV ejection fraction.
