potential degradation of the magnetic resonance
image, and potential reduced accuracy of SpO
2
measurements. Always remove oximetry devices and
attachments from the MRI environment before
scanning a patient.
• The use of cardio-green and other intravascular dyes at
certain concentrations may affect the accuracy of the
SpO
2
measurement.
• The SpO
2
function is calibrated to read functional
arterial oxygen saturation. Significant levels of
dysfunctional hemoglobins such as
carboxyhemoglobin or methemoglobin may affect the
accuracy of the SpO
2
measurement.
General Cautions
• As with any clip-on sensor, pressure is exerted. The
clinician should be cautious in using a clip-on sensor
on patients with compromised circulation (e.g.,
because of peripheral vascular disease or
vasoconstricting medications).
• Do not perform any testing or maintenance on a
sensor while it is being used to monitor a patient.
• Bright light sources (e.g., infrared heat lamps, bilirubin
lights, direct sunlight, operating room lights) may
interfere with the performance of the SpO
2
function.
To prevent such interference, cover the sensor with
opaque material.
General Notes
• A patient’s vital signs may vary dramatically during the
use of cardiovascular agents such as those that raise or
lower blood pressure or those that increase or decrease
heart rate.
• The Compact Monitor is compatible only with
NELLCOR sensors.
