• Periodically inspect the electrode application site to ensure skin quality. If the skin
quality changes, replace the electrodes or change the application site.
• No pacemaker rejection is present, and to keep pacemaker patients, and patients with
arrhythmias, under close surveillance. Recommend using the SpO2 function as the
primary heart rate source under those conditions.
! CAUTION
• Pacer pulses are not specifically rejected and may be treated as part of the MRI gradient
noise. Gradient filtering attempts to remove high frequency pulse shaped waveforms
from the ECG signal which may resemble pacer waveforms, and it is possible that the
pacer waveform may be removed with the gradient noise.
• Placing the Wireless ECG ePOD within the field of view during the MRI procedure may
cause artifact on the MRI image.
• Use with a higher SAR greatly increases the risk of patient burns. If scanned directly
across the plane of the ECG electrode element, a slight image distortion may be seen at
the skin surface where the ECG electrode element is positioned.
• High levels of RF energy may cause patient heating or burns. Use caution for scans
greater than 15 minutes and above SAR of 2 W/Kg.
• Discontinue use if skin irritation or inflammation is noticed around the electrode site.
6.1.1.1. 3881 ECG ePOD
The 3881 ECG ePOD is designed for use in the MRI magnet and wirelessly communicates with
the 3880 patient monitoring unit.
6.1.1.2. 1812 ECG Lead wires
The 1812 ECG lead wires are designed for use in the MRI environment with the 3880 MRI
Patient monitoring system.
6.1.1.3. ECG Electrode
Use an electrode designed for use with MRI systems to minimize the risk of heating during MRI
procedures and reduce the amount of MRI generated artifact on the ECG waveform. The
Electrode can be used as a single patch or multiple electrode patch to provide optimal
performance across a diverse patient populations.
6.1.1.4. Setup Limitations
The following factors may affect the accuracy of measurement:
• Heart rate extremes of less than 40 bpm or greater than 300 bpm
• Electrode placement
• MRI gradients
• Patient skin preparation
• ECG filter
• ECG lead view selected
• Pacemaker presence
• QRS signal strength
• Type of MRI system, scan and/or body area being scanned
