Correlation of CVP measurement via ultrasound and central venous catheter [ Time Frame: At data collection: this is a physiologic study ] [ Designated as safety issue: No ]
CVP as determined non-invasively with the transcutaneous ultrasound probe will correlate with a high degree of accuracy to the measurement obtained invasively by the catheter and pressure transducer.
Same as current

Correlation of CVP measurement via physical examination of IJV and EJV. [ Time Frame: At data collection: physiologic study ] [ Designated as safety issue: No ]
Despite its more tortuous course and smaller caliber, the external jugular vein will be as reliable (compared to the catheter) as the internal jugular to estimate CVP

Central Venous Pressure (CVP) Assessment by Ultrasound and Physical Examination
Use of Ultrasound to Determine Central Venous Pressure in Critically Ill Patients

Ultrasound may be useful for noninvasively determining the central venous pressure. We intend to compare the clinical examination of the neck veins; ultrasound delineation of the internal jugular vein; and the central venous pressure measured with an intravascular catheter.
