Exam Procedures

WARNING: (V5Ms only) Ensure that the friction brakes are unlocked and the flex controls are in
the neutral alignment position when you insert or withdraw the transducer. Advancing or
withdrawing the transducer while the transducer tip is bent and/or rigid can result in patient injury
or death.
WARNING: (V7M only) Ensure that the friction brake is unlocked and the flex control is in the
neutral alignment position when you insert or withdraw the transducer. Advancing or withdrawing
the transducer while the transducer tip is bent and/or rigid can result in patient injury or death.
WARNING: Do not use excessive force to advance or withdraw the transducer. Using excessive
force to advance or withdraw the transducer can result in patient injury or death. If you
encounter strong resistance during transducer articulation, discontinue the procedure. Identify
and address the cause of the resistance before resuming the procedure. Withdraw and redirect
the transducer as needed.
WARNING: To reduce the risk of pressure necrosis, put the transducer in the neutral position
when inserting or withdrawing it. Minimize pressure applied to the articulating section and distal
tip. Do not let the distal tip displace tissue for more than five minutes.
WARNING: Do not use the transesophageal transducer for any procedure requiring
hyperextension of the neck. Improper patient positioning can cause paralysis of the vocal cord.
WARNING: Always use a bite guard to prevent damage to the transducer from the patient's
teeth, which could, as a result, create potential mechanical and electrical hazards for the patient.
Using a bite guard also protects the patient's teeth.
Exam Procedures (V5Ms)
To use the V5Ms transducer during a transesophageal echocardiogram:
1. Remove dentures, if present, and place them in a protected area until after the procedure.
2. Place a transducer sheath on the transducer, if needed.
3. Place a bite guard around the distal end of the transducer.
4. Ensure that both friction brakes are unlocked and both flex controls are in the neutral
alignment position before inserting the transducer so that the transducer can bend to
accommodate the path of the esophagus.
5. Place the transducer in the patient's mouth, and secure the bite guard into place before
further advancing the transducer.
6. When the transducer has been inserted, press the array rotation control to change the
imaging scan plane.
7. As necessary, adjust the anterior/posterior and the left/right deflection using the flex
controls. Position the transducer for optimal acoustical contact and the required viewing
scan plane.
8. When the required scan plane is achieved and good acoustical contact is made, engage
both the anterior/posterior and the left/right friction brakes.
9. Unlock both friction brakes and move both flex controls to the neutral position to acquire
new echocardiographic views, which necessitate further advancement or withdrawal of the
transducer, or change in the deflection.
10. Unlock both friction brakes and move both flex controls to the neutral position to remove
the transducer.
