Placing the Temperature Sensor at the Body Site
When inserting the sensor into the mouth, use care not to scrape or tear the jacket on the
patient's teeth and ensure that the patient does not bite the sensor, as this could expose the

During MRI procedures a large amount of radio frequency (RF) energy is present, which may
cause a patient's body temperature to increase.
When making body temperature measurements, place the covered sensor at the esophageal or
rectal site according to the steps below.
