Abstract

There is a significant difference between measurements of the minimum inferior vena cava diameter observed in M- and B-mode ultrasound during the respiratory cycle in children under controlled ventilation. This results in imprecise respiratory variation of inferior vena cava diameter indices. Displacements of the inferior vena cava during the respiratory cycle may influence the reliability of ultrasonographic measurements, particularly in M-mode.
