13 Monitoring Invasive Pressure
195
Overview of Calibration Procedures
Calibration requirements depend on the situation and the type of transducer used. Recommendations
for the different calibration procedures are given in the table below.
Zeroing the Pressure Transducer
To avoid inaccurate pressure readings, the monitor requires a valid zero. Zero the transducer in
accordance with your hospital policy. You must perform a zero:
• when you use a new transducer or tubing
• every time you reconnect the transducer cable to the monitor
if you think the monitor's pressure readings are not correct.
Zeroing ICP (or IC1/IC2)
Your hospital guidelines may require you to zero the ICP transducer less frequently than other
transducers, due to the need for aseptic conditions. When you zero an ICP transducer, the zero values
are automatically stored and you will not be prompted to repeat the zero procedure.
If you want to simultaneously zero all pressures except ICP, disconnect the ICP transducer from the
monitor while zeroing. Reconnecting the transducer recalls the stored values.
WARNING
If you select the label ICP (or IC1/IC2), the measurement device uses the most recently stored zero.
Therefore, make sure you zeroed the transducer correctly in accordance with the transducer
manufacturer's instructions and your hospital policy. When you use a transducer that you cannot
rezero after placement, ensure that you keep the measuring device with the patient so that you are
certain you have the correct zero data for this patient.
