    BackgroundThis study aimed to detect the correlation of central venous pressure (CVP) with the internal jugular vein (IJV), common carotid artery (CCA), femoral vein (FV), and femoral artery (FA) diameters measured with ultrasound (USG) in patients under mechanical ventilation to evaluate whether they are suitable to be used as an alternative low-cost and noninvasive method for the detection of CVP.MethodsA total of 40 patients aged from 18 to 90 who had been receiving therapy in the intensive care unit (ICU) were included in the study. Central venous catheter was placed into the patients through right IJV or subclavian vein in their first 24-hour of hospitalization and the right atrium pressure (RAP) was measured from the catheter, the tip of which was confirmed to reach right atrium. In the same session, CCA, IJV, FA, and FV diameters were measured with USG and their correlations with CVP were calculated. In addition, correlations of the measured venous and artery diameters between each other were detected as well.ResultsThere was a significantly high correlation between CVP and CCA diameter (R = 0.603, P < .000). There was a significantly low correlation between CVP and IJV diameter (R = 0.352, P = .026), a significantly low correlation between FA and FV diameters (R = 0.317, P = .047), a significantly low correlation between FA and CCA diameters (R = 0.330, P = .038), and a significantly low correlation between IJV and CCA diameters (R = 0.364, P = .020).ConclusionCVP and CCA diameters exhibited a high correlation. For detection of CVP, the ultrasonographic CCA diameter measurement can be used as an alternative noninvasive method which is easy to use and minimally affected by measurement errors of individuals and which has low learning curve compared with the other measurement methods.Copyright © 2022 the Author(s).
