TEE Transducers
➤ To e n s u r e p a t i e n t s a f e t y a n d t o avoid unnecessary interruption while
scanning
• Ensure distal tip temperature accuracy by entering an accurate patient core
temperature.
• Decrease the transducer temperature by using the Power knob before intro-
ducing a TEE transducer to decrease acoustic output, and keep the control at
the lowest possible setting during an exam. For information about controlling
the power, see the Help.
• Use the TEE Manual Auto-Cool safety feature to enter the patient tempera-
ture if it is above 37°C (98.6°F), as described in the next section.
TEE Manual Auto-Cool Safety Feature
Use the TEE Manual Auto-Cool feature to enter above-normal patient tempera-
tures. By default, the system shows both the patient and distal tip temperature
while scanning.
NOTE
The patient temperature displayed on the ultrasound screen is always either 37°C
(98.6°F) or the temperature that you manually enter. The system does not 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 distal tip 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 42.0°C (107.6°F) or lower.
• If the temperature reaches 46.5°C (115.7°F) when using the T6H transducer,
or 45°C (113°F) when using the S7-2omni or the S7-3t transducer, the system
shuts down. You must turn it off and then on to restart it.
