“…Even though there were some other noninvasive methods of CVP measurement, such as controlled compression sonography on the peripheral vein, 20,21 forearm volume plethysmography, 22,23 and neck inductive plethysmography, 24 they relied on additional instruments that are not readily available in routine clinical practice. By contrast, the instruments that we use in the new method of quantification of CVP are just a ruler and a pencil besides a portable ultrasound machine, which is widely available.…”

Background— The central venous pressure (CVP) is essential for assessing the cardiac preload and circulating blood volume in clinic. The invasive CVP measurement by central venous catheter has been reported with various complications. The aim of this study was to develop a new noninvasive method for quantification of CVP by ultrasound. Methods and Results— Seventy-six patients who had their CVP monitored for intraoperative or postoperative management were recruited. By accurate location of the collapse point of the internal jugular vein and the center of the right atrium using ultrasound imaging, the height of the fluid column between those 2 points was measured as the noninvasive CVP (CVPn). A total of 118 measurements were performed and compared with the invasive CVP (CVPi). Linear correlation analysis revealed a significant correlation between CVPi and CVPn (preoperative measurements, r =0.90; P <0.01 and postoperative measurements, r =0.93; P <0.01). Bland–Altman plots showed a good agreement between CVPi and CVPn with the mean difference of 0.22 mm Hg (preoperative measurements) and −0.09 mm Hg (postoperative measurements), respectively. Conclusions— The new noninvasive CVP quantification method based on the location of both the collapse point of internal jugular vein and the center of right atrium by ultrasound could be used as a reliable approach for monitoring the hemodynamic status in clinic.

“…A literature search found 1 letter to the editor suggesting that real-time ultrasound imaging of the internal jugular vein could be used to qualitatively determine jugular venous pressure 18 and 3 studies using ultrasound in conjunction with a pressure transducer or manometer to determine the pressure needed to collapse the vein (either the internal jugular or a peripheral vein), with subsequent correlation to CVP. [19][20][21] These latter techniques appear to be cumbersome and require custom equipment that is not readily available in most hospitals.…”

“…The static pressure induces additional stresses to the vein wall and the base cuff pressure (P) of a forearm vein is measured to be 50 mmHg [14]. Considering the vein inner radius (r) of 2.5 mm with a uniform wall thickness (h) of 0.54 mm [15], the base circumferential stress in the vein wall (S θ ) can be estimated by using the Laplace law, 1 2 16,17].…”
