Central Venous Pressure (CVP) Assessment by Ultrasound and Physical Examination

April 5, 2010 updated by: University of Iowa

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.

Exclusion Criteria:

  • subjects with only a femoral venous catheter.
  • subjects whose CVP measurement by the indwelling catheter exceeds 20cm of water.
  • subjects younger than 18 years old.
  • inability to obtain informed consent from the subject or the subjects authorized representative.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation of CVP measurement via ultrasound and central venous catheter
Time Frame: At data collection: this is a physiologic study
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.
At data collection: this is a physiologic study

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation of CVP measurement via physical examination of IJV and EJV.
Time Frame: At data collection: physiologic study
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
At data collection: physiologic study
