Ensuring Proper Transducer Maintenance
Thoroughly examine the transducer and test the controls before each exam. Be
sure to check for excessive flexibility in the tip. See "TEE Transducer Inspection"
on page 282.
TEE Temperature Sensing
The transesophageal transducers contain built-in temperature sensors near the
distal tip. The sensor monitors the transducer’s temperature to prevent potential
burning of esophageal tissue. The patient’s actual temperature is required to
accurately estimate the distal tip temperature. By default the system assumes
that the patient temperature is 37°C (98.6°F). You must manually enter the
actual patient temperature if it is above 37°C (98.6°F).
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 291.
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.
