MR 400 Preparation for IBP Monitoring
Follow the procedure below to prepare the MR400 for IBP monitoring when using the Expression
MR IBP DPT Kits (Adult / Pediatric, REF 989803194631; and, Infant/Neonatal, REF 989803194641).
As there are preparation differences, always follow the appropriate procedure.
To prepare the MR400 for IBP monitoring using transducer kits other than those referenced
below, or for components added to the monitoring system, refer to applicable manufacturer's
instructions for set up and use.
MRI scanning, which can lead to pressure reading inaccuracies. Always mount the invasive
blood pressure transducer away from areas where vibration is likely to occur.

Invasive blood pressure transducers are sensitive to vibrations that can occur during
The fluid within the pressure transducer system is a conductive connection to the
patient, and must not contact other conductive parts, including earth ground.
Do not allow fluids to enter the electrical connections of the transducer cables. Erratic
readings may result.
Always reference the manufacturer's instructions and follow the safe use instructions
included with the IBP transducer kit when monitoring invasive blood pressure.
Never attach the pressure transducer(s) directly to the patient as excessive heating can
occur resulting in burn injuries to the patient.
If air bubbles appear in the tubing system, flush the system with the infusion solution
again. Air bubbles may lead to a wrong pressure reading.
Transducers do not protect against burns when used with high-frequency (HF)
A transducer cable or other cable that becomes inadvertently looped during an MRI
examination may act as conductive lines for RF induced currents, resulting in
excessive heating and possible burns. When transducer cables or other cables form a
conductive loop in contact with the patient's tissue, minor to severe burning can result.
Do not allow the transducer cable or other cable to touch the patient or to become
looped. Please refer to the additional information in Appendix E to prevent excessive
heating associated with MRI procedures.
