Continuous measurement of central venous pressure by manometry.

An alternative method is described for measurement of central venous pressure by insertion of a right atrial catheter with a connection to a fluid-column manometer. With this method, the central venous pressure can be monitored by visual inspection of the manometer column; the stopcock does not need turning; the manometer column does not need refilling; and the catheter is always being flushed, eliminating the risk of clotting.
