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

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • adult medical or surgical ICU patients who have preexisting central venous (jugular/subclavian only) catheters.

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.

Treatment and study plan

Primary outcomes

  1. 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.

Secondary outcomes

  1. 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
