• Insert, remove, and operate the transducer properly.
• Ensure that the transducer handle does not rest on or touch the patient.
• Use protective equipment, such as a bite guard and a market-approved
sterile transducer cover during a TEE study. See "TEE Accessories and
Supplies" on page 292.
• Do not allow water or other liquids to come in contact with the interior
of the system, the interior of the transducer connector, the inside of the
transducer control handle, or to drip onto the keyboard.
• Minimize the possibility of transducer tip fold-over. This problem has
occurred rarely, but its consequences can be serious. See "Tip Fold-Over"
in the Help.
To prevent tissue damage such as pressure necrosis, gastroesophageal lacerations,
bleeding, tearing of adhesions, ligament damage, and perforation, observe the
following warnings and cautions.
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. (This
does not apply to the S8-3t TEE transducer.)
• When using the S8-3t TEE transducer, do not use the deflection brake on
pediatric patients.
• Whenever the TEE transducer is not being used during a procedure, ensure
that it is in freewheeling mode and unplugged from the system.
• 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.
(This does not apply to the S8-3t TEE transducer.)
• For the S8-3t TEE transducer only: To protect the patient and the
transducer, the tip of the transducer must be straightened and the deflection
brake must be off when inserting or withdrawing the transducer. The tip
is straight when the deflection control is aligned along the distal end of the
