To prevent tissue damage such as pressure necrosis, gastroesophageal lacerations,
bleeding, tearing of adhesions, ligament damage, and perforation, observe the
following warnings. See "TEE Transducer References" on page 263.
WARNINGS
• Never apply excessive force when inserting or withdrawing a TEE
transducer, or when operating the transducer deflection controls.
• Lock medial/lateral movement of the TEE transducer during insertion.
• Whenever the TEE transducer is not being used during a procedure, ensure
that it is in freewheeling mode and unplugged from the system.
• Do not allow the TEE transducer to remain at a maximum deflection for
long periods of time.
• 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.
• 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.
• 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.
Connecting an S7-2omni Transducer
NOTE
Before you connect the S7-2omni TEE transducer, be sure the tip and shaft are
straight. When you connect the transducer, it automatically calibrates itself to
the 0-degree (horizontal plane) position.
If the "Calibration failed" message appears, see "Calibrating the TEE Transducer"
on page 246.
1. Plug the S7-2omni transducer into a transducer receptacle on the system.
