When to Zero the Transducer Whenever the reference point on the patient changes the air-fluid interface changes.

The nurse must be confident that central venous pressurecentral venous pressureCentral venous pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system.https://en.wikipedia.org › wiki › Central_venous_pressureCentral venous pressure - Wikipedia (CVP) and arterial BP measurements are accurate. The phlebostatic axis is the reference point for zeroing the hemodynamic monitoring device. This reference point is important because it helps to ensure the accuracy of the various pressure readings.
