Tee Deflection Control Basics - Philips EPIQ 7 User Manual

TEE Deflection Control Basics

• Require periodic electrical safety checks to ensure that the grounding system in your area
remains intact.
• If the transducer is left in a patient during periods when imaging is not taking place, unplug
the transducer from the system to reduce the possibility of leakage current or ESU
interaction. Also make sure that the deflection control brakes are off and that the
transducer is in freewheeling mode.
• Always remove the transducer from the patient before defibrillation.
TEE Deflection Control Basics
The deflection controls on the TEE transducer move the deflection area, located between the
distal tip and flexible shaft. The deflection area bends when you operate the controls,
permitting anterior, posterior, and lateral positioning.
Deflection Control Movement
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
WARNING
Never apply excessive force when inserting or withdrawing a TEE transducer, or when
operating the transducer deflection controls.
WARNING
Lock medial/lateral movement of the TEE transducer during insertion.
