17 - 4 BeneVision N Series Patient Monitor Operator’s Manual
1. Zero the Codman ICP transducer. For more information, see section 17.4.1Zeroing the Codman ICP 
transducer.
2. Disconnect the ICP transducer and ICP adapter cable. Follow the manufacturer’s instructions to apply the 
ICP transducer to the patient.
3. Reconnect the ICP transducer and ICP adapter cable. 
4. Check that the zero reference value displayed on the monitor is consistent with that recorded on the ICP 
transducer. 
◆ Consistent: select Accept.
◆ Inconsistent: input the zero reference value recorded on the ICP transducer, and select Accept.
If you have to transfer the patient who is taking ICP measurement, check that the target monitor supports the 
Codman ICP transducer. For more information, see 17.4.1Zeroing the Codman ICP transducer. If the target 
monitor does not support the Codman ICP transducer, do not use it for ICP monitoring.
Follow this procedure to transfer the patient:
1. Disconnect the ICP adapter cable from the measurement module, or remove the module from the monitor.
2. Connect the ICP adapter cable, measurement module, and the target monitor, or insert the measurement 
module into the target monitor.
3. Check that the zero reference value displayed on the monitor is consistent with that recorded on the ICP 
transducer. 
◆ Consistent: select Accept.
◆ Inconsistent: input the zero reference value recorded on the ICP transducer, and select Accept.
• If monitors of different brands are used to zero the Codman ICP transducer, the zero reference 
values can be different. Use a Mindray monitor to Zero the Codman ICP transducer if you will take
ICP measurement using a Mindray monitor. Otherwise the ICP measurement can be inaccurate.
17.5 IBP Display
The IBP measurement is displayed on the monitor as a waveform and numeric pressures. For arterial pressure, 
the IBP numeric area displays systolic pressure, diastolic pressure and mean pressure. For venous pressure, the 
IBP numeric area displays only the mean pressure. The figure below shows the waveform and numerics for the 
Art pressure.
