NOTE
If you want the temperature display enabled by default, turn on the temperature
display and then create a preset as described in "Creating Quick Save Presets"
on page 181.
1. Display the Preset/Transducer touch screen by touching
Preset/Transducer.
2. Touch Temp Display to display or hide the temperature display.
3. Touch Temp Units to switch the temperature scale between Farenheit and
Celsius.
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 291 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.
