Normal CVP can be measured from two points of reference:
- Sternum: 0–14 cm H2O
- Midaxillary line: 8–15 cm H2O
CVP can be measured by connecting the patient's central venous catheter to a special infusion set which is connected to a small diameter water column. If the water column is calibrated properly the height of the column indicates the CVP.
In most intensive care units, facilities are available to measure CVP continuously.
Normal values are 5-10 mmHg

Famous quotes containing the word measurement:
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
