Слайд 18

The diameter of the Inferior vena cava (IVC) and the percent

decrease in the diameter during inspiration correlate with RA and PA pressure.
The normal IVC diameter is less than 1.7 cm. There is a 50% decrease in the diameter when the RA pressure is normal (0-5 mm Hg).
A dilated IVC (1.7 cm) with normal inspiratory collapse (>50%) is suggestive of a mildly elevated RA pressure (6-10 mm Hg).
When the inspiratory collapse is less than 50%, the RA pressure is usually between 10 and 15 mm Hg.
Finally, a dilated IVC without any collapse suggests a markedly increased RA pressure of greater than 15 mm Hg.
