Ensuring Safe TEE Temperatures
To ensure patient safety and to avoid unnecessary interruption while scanning, follow these
suggestions:
• Ensure distal-tip-temperature accuracy by entering an accurate patient core temperature.
• Decrease the transducer temperature by using the Output Power knob before introducing a
TEE transducer to decrease acoustic output, and keep the control at the lowest possible
setting during an exam.
• Use the TEE Manual Auto-Cool safety feature to enter the patient temperature if it is above
37°C (98.6°F) as described in “Entering Patient Temperature” on page 231 .
• If the transducer temperature begins to rise when you are using high-power modes such as
Live 3D, Color, Tissue Harmonic Imaging, and Doppler, temporarily switching to
fundamental 2D mode or freezing the image can help cool the transducer.
Manual Auto-Cool Feature
Use the TEE Manual Auto-Cool safety feature to enter above-normal patient temperatures.
When the temperature display is enabled, you can see both the patient temperature and the
distal tip temperature while scanning.
NOTE
The patient temperature shown on the ultrasound display is always either 37°C (98.6°F) or the
temperature that you manually enter. The system does not monitor or report the actual patient
temperature.
If the distal tip temperature reaches 41°C (105.8°F), a warning message appears and the
transducer temperature is displayed in inverse video. If the temperature reaches 42.5°C
(108.5°F), a warning appears with the patient and the transducer temperatures, and the system
stops imaging until the distal tip cools to below 42°C (107.6°F). The system shuts down if the
patient-applied part temperature of the TEE transducer exceeds 42.5°C (108.5°F), given an
entered patient temperature of 37°C (98.6°F). It resumes scanning when the temperature falls
below 42°C (107.6°F) . If the patient temperature is higher than 37°C (98.6°F), the system
shutdown temperature adjusts accordingly. You may need to restart the system by turning it
on.
