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.

| Measure | Description | Time Frame |
|---|---|---|
| Correlation of CVP measurement via ultrasound and central venous catheter | 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 |
| Measure | Description | Time Frame |
|---|---|---|
| Correlation of CVP measurement via physical examination of IJV and EJV. | 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 |
