Review: RAP can be determined non-invasively.
The American Society of Echo (ASE) and most cardiology labs endorse the use of the parameters shown in this chart.
This chart shows a ballpark range of RAP based on IVC size and respiratory variation.
For example, a large non-varying IVC is an elevated RAP – somewhere between 10 and 20; the average of 15 is typically used.
For example, a very small IVC with significant variation corresponds to a low CVP – somewhere around 0-5; the average of 3 is typically used.
