Clinical Utility of Superior Vena Cava Flow Velocity Waveform Measured from the Subcostal Window for Estimating Right Atrial Pressure
2022, Journal of the American Society of EchocardiographyCitation Excerpt :This may be because the sampling position was closer to the right atrium in the subcostal approach than the supraclavicular approach. A previous study demonstrated that central venous pressure measured within the femoral vein, which is farther away from the right atrium, is less reliable.29 Thus, we speculated that SVC flow recorded from the subcostal window, which is closer to the right atrium, could more accurately reflect the RAP waveforms (Supplemental Figure 6).
Iliac venous pressure estimates central venous pressure after laparotomy
2014, Journal of Surgical ResearchCitation Excerpt :Despite the frequency in which femoral lines are placed in acute resuscitation, the use of pressure measurements from femoral-placed lines positioned in the external or common iliac is not routinely performed. A limited number of studies have evaluated the use of iliac venous pressure (IVP) measured from femoral lines as a measure of CVP in preclinical and clinical models and demonstrated no significant difference in the pressure measurements [7–20]. However, no studies have evaluated IVPs measured from femoral lines after laparotomy.
Estimation of central venous pressure using inferior vena caval pressure from a femoral endovascular cooling catheter
2013, American Journal of Emergency MedicineCitation Excerpt :Central venous pressure monitoring in patients undergoing femoral endovascular cooling may require the placement of another catheter near the RA because the tip of the currently available femoral endovascular cooling catheter resides in the abdominal inferior vena cava. Several previous studies have shown a high correlation between the abdominal inferior vena caval pressure (IVCP) and the CVP measured in the superior vena caval pressure (SVCP) in severely ill patients [5-7]. However, to our knowledge, there is no study examining the accuracy of IVCP relative to SVCP in patients undergoing femoral endovascular cooling.
Ultrasonography of jugular vein as a marker of hypovolemia in healthy volunteers
2013, American Journal of Emergency MedicineCitation Excerpt :Hypovolemic identification using many different noninvazive techniques has been studied previously. The relationship between the diameter of the inferior vena cava (IVC) and the intravascular volume has been investigated repeatedly [3,4,6-12]. The sensitivity and specificity of the IVC collapse index and central venous pressure (CVP) correlation are 100% and 88.9%, respectively [13].
