TEE Temperature Sensing Transesophageal Transducers

Patient Temperature

Entering a patient's temperature enables the Auto-Cool feature to calculate tip temperature
more accurately, which can prevent unnecessary interruptions while scanning. If a patient's
temperature is above normal, entering a temperature can avoid exposing the patient to
excessive temperatures.
Always check the patient's temperature before inserting a TEE transducer. If it is above normal,
whether from fever or therapeutic heating from a cardiac bypass heart-lung machine, perform
the procedure in "Entering Patient Temperature" on page 231 before inserting the transducer.
Also, follow that procedure if a patient's temperature rises during a study.
Measure the patient's core temperature, or more specifically, the actual temperature in the
esophagus. For patients undergoing surgery, determine the temperature in the esophagus by
direct measurement or by monitoring the temperature of blood returning from the bypass
pump heat exchanger.
For closed-chest situations, rectal temperature is the best estimate of core temperature. You
can also use oral temperatures, even though they can be one degree lower than the core
temperature. If you measure an auxiliary temperature, which can be two degrees lower than
the core temperature, add one or two degrees.

Entering Patient Temperature

1. If necessary, select the TEE transducer.
2. Turn Pat Temp to enter the patient's measured temperature.
NOTE
Each time you turn off or reset the system, or enter a new patient ID, the system assumes that
the patient temperature is 37°C (98.6°F).

Resuming Imaging After Auto-Cool

If the distal tip temperature drops below 42.5°C (108.5°F), the system resumes imaging. If the
Auto-Cool message persists longer than 1 minute or an error message appears, contact your
Philips service representative.
