Z. Reda et al., EFFECT OF AIRWAY PRESSURE ON INFERIOR VENA-CAVA PRESSURE AS A MEASUREOF CENTRAL VENOUS-PRESSURE IN CHILDREN, The Journal of pediatrics, 126(6), 1995, pp. 961-965
We evaluated the effect of elevated airway pressure on the validity of
intravascular pressure obtained in the distal inferior vena cava (IVC
) as a measure of central venous pressure (CVP) in a group of children
receiving mechanical ventilation. The IVC pressure correlated well wi
th CVP in the patients without abdominal distention, but the disparity
was wider in those with abdominal distention. Elevated mean airway pr
essure or positive end-expiratory pressure had no effect on the relati
onship of IVC to CVP.
