Table 4 Estimation of RA pressure based on Inferior Vena Cava diameter and collapse
From: WEB downloadable software for training in cardiovascular hemodynamics in the (3-D) stress echo lab
Inferior vena cava diameter (cm) | Respiratory collapse (%) | RAP (mmHg) |
|---|---|---|
< 2.1 | ≥ 50% | 3 (0-5) |
> 2.1 | < 50% | 15 |
> 2.1 | ≥ 50% | 8 (5-10) |
< 2.1 | < 50% | 8 (5-10) |
