TEE Transducers
WARNING
To prevent tissue damage, Philips recommends that the tip of the transducer be
straightened and both friction brakes released before you withdraw the trans-
ducer from the patient. In the neutral position, the tip is straight when both white
circles on the control wheels are aligned and point toward the center of the array
rotation button.
CAUTION
When repositioning or withdrawing a TEE transducer, put the controls in free-
wheeling mode. Also, whenever the transducer is not being used during a proce-
dure, make sure it is in freewheeling mode and is unplugged from the system.
Tem pe ra tu re C on tr ol s
The TEE transducers discussed in this section have temperature sensors in the
distal tip. An automatic warning appears on the ultrasound display if the distal tip
temperature exceeds a specified limit, and the system discontinues scanning.
Use the TEE Auto-Cool feature to enter above-normal patient temperatures.
Entering a patient’s temperature enables the system to calculate tip temperature
more accurately, and can prevent unnecessary interruptions while scanning. For
more details of the TEE Auto-Cool feature, see “TEE Manual Auto-Cool Safety
Feature” on page 229.
