TEE Transducers
If the distal tip temperature reaches 42.5°C (108.5°F) during imaging, an
Auto-Cool in progress message is displayed, as shown in Figure 10-11.
Figure 10-11 TEE Auto-Cool in Progress Display
Resuming Imaging After an Auto-Cool Interruption
When the distal tip temperature drops below 42.0°C (107.6°F), the system
resumes imaging. If the Auto-Cool message persists longer than 1 minute or an
error message is displayed, contact your Philips Ultrasound service representa-
tive.
WARNING
The Reconnect the transducer error message is often caused by a poorly
seated transducer connector, but could be caused by a failure in the Auto-Cool
Safety logic. In the case of a logic failure, distal tip temperatures could reach
46.5°C (115.7°F) in hyperthermic patients (40°C to 41°C (104°F to 105.8°F))
before the error causes scanning to stop. At this temperature, esophageal burns
may occur.
