The number, location, and diameter of air emboli
AIR EMBOLUS
A total of 42 air emboli were observed in 21 cases of air emboli from the control group, with a diameter of 0.8–11.8 mm [mean: (1.950 ± 1.719) mm], including 17 air emboli in the right atrium, 14 air emboli in the right ventricle, 8 air emboli in the main pulmonary artery, and 3 air emboli in the superior vena cava (Fig.
