Overview

Brief Summary

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.

Eligibility Criteria

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.

Outcomes

Primary Outcomes

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.
