tone
Excessive patient motion, the MRI scan sequence or electrical interference is causing noise in the
SpO2 system:
Stop any patient motion, especially at the monitored site.
Ensure that the module is placed outside of the MR bore.
Ensure the clip (or grip) is positioned in a way that does not expose it to bright ambient light.
Non-Pulsat

tone
The detected pulse is too weak for reliable reporting of SpO2 measurements:
Check the patient’s condition.
Check the clip (or grip) position and alignment on the patient then re-position or re-apply as
necessary.
Try a different limb or site.
Probe Off

Pulse?

Pulse reading is questionable. The SpO2 attachment may not be applied optimally or the tissue at
the application site may be too opaque:
Check the alignment of the clip (or grip) on the patient.
Try a different limb or site.
Searching

The SpO2 attachment was just applied or it has shifted position on the patient:
If the clip (or grip) was just applied, allow about 20 seconds for the system to lock on to a good
pulse.
Check the clip (or grip) position and reposition it if necessary.
Replace the SpO2 probe.
If the message persists, contact technical support or authorized service personnel.
