Temperature Controls And Safeguards (V7M) - Siemens Acuson S1000 Instructions For Use Manual

Temperature Controls and Safeguards (V7M)

WARNING: Disconnect the transducer if the system displays the message indicating that the
maximum thermal limit is exceeded. (The transducer temperature is 43°C or higher.) Failure to
disconnect a transesophageal transducer that has exceeded the maximum thermal limit can
burn the patient's esophagus. Reconnect the transducer after the transducer has cooled. Or,
use a different transducer.
Because some concerns have been raised about possible thermal injury to the esophagus due
to the local buildup of heat during transesophageal echocardiography, the transesophageal
transducer incorporates a shut-off mechanism in the interest of patient safety in the unlikely
event overheating should occur. For additional information on temperature limitation, refer to
EN 60601-2-37 and IEC 60601-2-37.
A temperature sensor mounted in the distal tip of the transducer monitors the temperature of
the scanning array and displays the temperature on the screen.
When the temperature is 37°C or below, the temperature indicator displays <37°C.

When the temperature is above 37°C, the system displays the actual temperature. When

the temperature reaches 40°C, the temperature indicator is highlighted.
Lens Temp: 40°C
Example of temperature indicator displayed above scan plan icon.
When the temperature reaches 41°C and you choose to override the software and

continue to scan the patient, OVERRIDE displays next to the scan plane icon.
Lens Temp: 41°C
