Rui found central venous pressure can be measured by ultrasonography According to an article in the American Journal of Cardiology, forearm controlled compression ultrasound can provide a measure of central venous pressure, through the superficial peripheral vein without passing Intravenous catheterization.
Dr. Christoph Thalhammer of the University Hospital of Basel and his colleagues point out that central venous pressure is important for monitoring hemodynamic changes in critically ill patients. To test the role of pressure ultrasound in measuring central venous pressure, they enrolled 10 healthy volunteers for initial study.
It was found that there was a strong correlation between invasive and non-invasive measures in the range of hypertension caused by a wide experiment. They then enrolled 50 intensive care patients to evaluate this method, one for the forearm to be placed below the heart level and one for the forearm to be placed at the heart level. It was found that the difference in central venous pressure measured by invasive or non-invasive means was negligible.
The researchers pointed out that although this method is not suitable for continuous monitoring, it provides an alternative means of evaluating central venous pressure in emergency patients. ——China Medicine 123 Network
