How to estimate right atrial pressure with echocardiography ?

Posted Nov 03 2009 10:01pm

Estimation of right atrial pressure (Often referred to as  central venous pressure (CVP) is a common hemodynamic excercise both at the bed side and in echocardiographic lab. A venous catheter inside the right atrium is probably  the best way to measure it accurately .But, there are  practical issues  for  putting and maintaining a CVP catheter. ( & We also know , what happened to the concept of routine  swan  catheter in critically ill patients !).

A  rapid bed side echocardiography  can give us a fairly accurate estimation of RA pressure . We  don’t even need look into the heart , what you need is imaging the inferior vena cava , it’s size and it’s  behavior  with respiration  . You don’t require  a doppler probe either ! With these two parameters one can decode the mean RA pressure. This  modality is rarely used in the ICUs , it can be a simple aid to fluid management .

Shrewd clinicians would argue , we have a natural catheter inside the right atrium, ie the   internal jugular vein   This gives us a unique opportunity to study the moment to moment RV, RA pressure . And .  .  . yes ,  we know it but we rarely respect the neck veins !
