Transesophageal Transducers TEE Deflection Control Basics
WARNING
Whenever the TEE transducer is not being used during a procedure, ensure that it is in
freewheeling mode and unplugged from the system.
WARNING
Do not allow the TEE transducer to remain at a maximum deflection for long periods of time.
WARNING
To prevent tissue damage, Philips recommends that the tip of the TEE transducer be
straightened and both detent brakes released before you reposition the transducer or
withdraw the transducer from the patient. In the neutral position, the tip is straight when the
indicators on the control wheels are aligned and point toward the center of the array rotation
button.
WARNING
Bite guards are mandatory; protective covers are recommended for TEE transducers, except
in China and Japan, where protective transducer covers are mandatory for TEE transducers.
WARNING
To avoid damaging gastroscope cables, be sure that the distal tip of the transducer is in the
neutral (straight) position when inserting a transducer into, or removing it from, the
transducer cover.
