TEE Transducer Inspection
Carefully inspect the entire surface of the distal tip and flexible shaft for
protrusions, holes, dents, abrasions, cuts, burrs, or cracks that could be extremely
hazardous to both you and your patient.
Carefully feel the tip and shaft, and inspect the entire transducer. If you suspect
an electrical problem, follow the electrical safety check procedure described in
"Electrical Safety Check for TEE Transducers" in the "Transesophageal
Transducers" section of the User Manual.
Also check for excessive flexibility in the tip, particularly in the medial/lateral
direction. Do not use the transducer if the tip is extremely flexible. If you have
any questions about tip flexibility, contact your Philips service representative.
TEE Transducer Controls Inspection
Use the deflection controls to position the tip in every possible direction, both
to ensure that the controls work properly and to get used to the feel of the TEE
transducer. Make sure that the controls operate smoothly without binding, and
that you can achieve all possible positions easily before introducing the TEE
transducer into the patient.
Test the detent brakes and freewheeling mode. Remember that the controls
must be in freewheeling mode (no deflection and no brake resistance) when
repositioning or withdrawing the transducer, as well as whenever you are not
imaging. See "Manipulating the S7-2omni and the X7-2t Tip" on page 258.
Special Considerations for TEE Studies
Special considerations regarding TEE studies are advisable for patients with
existing gastroesophageal abnormalities, such as esophageal varices, hiatal hernia,
tumor, diverticula, esophageal webs and rings, fistulae, or peptic ulcers, as well
