Why the study?
Current noninvasive estimation of right atrial pressure by bedside jugular venous pressure examination or inferior vena cava measurement during comprehensive echocardiography offers imprecise estimates of actual right atrial pressure.
Does point-of-care ultrasound evaluation of the right jugular vein and right atrial depth accurately estimate right atrial pressure compared to invasive catheter measurement?
Does point-of-care ultrasound evaluation of the right jugular vein and right atrial depth accurately estimate right atrial pressure compared to invasive catheter measurement?
Point-of-care ultrasound of the right jugular vein and right atrial depth provides a simple, noninvasive method to estimate right atrial pressure within 3 mm Hg of invasive measurements in most patients.
May support bedside ultrasound for RAP estimation; leaves open need for prospective validation before wider use.
BACKGROUND: Current noninvasive estimation of right atrial pressure (RAP) by either bedside jugular venous pressure exam or inferior vena cava measurement during a comprehensive echocardiogram offers imprecise estimates of actual RAP. METHODS: ) both as measured and as corrected for where the catheter was zeroed. CONCLUSION: This simple ultrasound evaluation of RAD and the right jugular vein correlates well with actual RAP and can accurately estimate RAP within 3 mm Hg in most patients. This has the potential to improve our bedside volume status exam, as well as improve the accuracy of RAP estimation during comprehensive echocardiogram.
