“…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.

“…9 Previous attempts at noninvasive hemodynamic monitoring using plethysmography, thoracic electrical bioimpedance, and external Doppler probes have shown these methods to be cumbersome or inaccurate. [10][11][12][13] Other investigators have used echocardiography 14,15 and handheld ultrasound 16 to image the diameter of the inferior vena cava in order to assess intravascular volume status, but these techniques require expertise in sonographic imaging. An alternative technique is to measure peripheral venous pressure, which correlates with CVP.…”

Comparison between noninvasive measurement of central venous pressure using near infrared spectroscopy with an invasive central venous pressure monitoring in cardiac surgical Intensive Care Unit

Introduction:Central venous pressure (CVP) measurement is essential in the management of certain clinical situations, including cardiac failure, volume overload and sepsis. CVP measurement requires catheterization of the central vein which is invasive and may lead to complications. The aim of this study was to evaluate the accuracy of measurement of CVP using a new noninvasive method based on near infrared spectroscopy (NIRS) in a group of cardiac surgical Intensive Care Unit (ICU) patients.Methodology:Thirty patients in cardiac surgical ICU were enrolled in the study who had an in situ central venous catheter (CVC). Sixty measurements were recorded in 1 h for each patient. A total of 1800 values were compared between noninvasive CVP (CVPn) obtained from Mespere VENUS 2000 CVP system and invasive CVP (CVPi) obtained from CVC.Results:Strong positive correlation was found between CVPi and CVPn (R = 0.9272, P < 0.0001). Linear regression equation - CVPi = 0.5404 + 0.8875 × CVPn (r2 = 0.86, P < 0.001), Bland–Altman bias plots showed mean difference ± standard deviation and limits of agreement: −0.31 ± 1.36 and − 2.99 to + 2.37 (CVPi–CVPn).Conclusion:Noninvasive assessment of the CVP based on NIRS yields readings consistently close to those measured invasively. CVPn may be a clinically useful substitute for CVPi measurements with an advantage of being simple and continuous. It is a promising tool for early management of acute state wherein knowledge of CVP is helpful.
