ZOLL M Series Invasive Blood Pressure 5
Taking Measurements
If the catheter, transducer and IBP cable are properly attached, the IBP traces display immediately. The
IBP numerical values display once the transducer has been zeroed. Unless it is an emergency situation
where quick reaction is essential, you should always check that the settings are set properly. You can
access all IBP settings through the IBP menu.
When reading the blood pressure values on the display, keep in mind that the following conditions can
influence IBP measurement accuracy:
• Catheter placement in the vasculature. Artifact such as catheter whip should be handled per your
established clinical protocols.
• Position of the transducer stopcock, catheter and flush port.
• Saline line flushes which will temporarily interrupt accurate pressure measurement.
• Position of the transducer relative to the patient’s phlebostatic axis or catheter tip.
• Patient movement.
• Catheter clogging.
• Air bubbles in catheter or transducer dome.
C AUTION ! Flush catheter regularly while taking IBP measurements. Always view the IBP
trace to ensure pressure measurements are based on a physiological waveform.
