VIII. In the MR Room
WARNINGS
• The IBP transducer must not be allowed past the 5,000 gauss line, or transducer
failure, inaccurate readings, noisy MRI images or patient burn may result.
• Never place the pressure transducer’s stopcocks or port covers within 8 cm (3.2
inches) of the field of view of the MR bore as inaccurate readings or noisy MRI images
can result.
• An offset occurs when the pressure transducer is repositioned in the magnetic field.
The transducer must be zeroed prior to the MRI examination after the transducer is in
its final setup position. Moving the transducer after zeroing may cause a measurement
offset to occur.
IntheMRroom,ensurethatthetransducerislevelwiththeheartthatthetransducerinterface

WARNING
Non-physiological pulsatile P1 (or P2) waveform (for example, those found during intra-
aortic balloon pump use) can lead to inaccurate blood pressure readings. If questionable
values are observed, recheck the patient’s pressures by alternate means before administering
medication or therapy.
