6 Transesophageal Transducer
Instructions for Use 6 - 13
Preparation for Use
WARNING: When using an endocavity or intraoperative transducer with a BF or CF type applied
part, the patient leakage currents may be additive.
WARNING: The leakage current test for transesophageal transducers must be done prior to
each use in order to reduce the likelihood of harm to the patient. Refer to the manufacturer's
instructions included with the tester.
WARNING: Prior to each use, inspect the endocavity or intraoperative transducer for signs of
mechanical damage such as cracks, cuts, tears, perforations, or protrusions. Do not use the
transducer if the transducer appears damaged in any way. A damaged transducer could cut the
patient or user and compromise the electrical safety of the transducer, causing possible patient
or user injury. Contact your local Siemens representative.
WARNING: (V7M only) Prior to each use, confirm the maximum deflection angle range of the
distal tip is 90° to 120° upward and 60° to 90° downward. If the up/down deflection exceeds the
maximum deflection angle range, do not use the transesophageal transducer. The distal tip
could fold over in the esophagus, causing possible patient injury. Contact your local Siemens
representative.
Prior to First Use
Proper precautions reduce risks to the patient and the equipment.
 Review the Safety and Care section.
 Thoroughly understand the features and operation of the transesophageal transducer,
particularly the use of the flex controls and friction brakes.
 Clean and high-level disinfect the transesophageal transducer prior to its first use.
 Perform a leakage current test on the transducer. Refer to the manufacturer's instructions
included with the tester.
Prior to Each Use
Review this checklist before each use of the transesophageal transducer to ensure patient
safety, comfort, and confidence.
 Review patient history to ensure contraindications do not apply.
 Thoroughly inspect the transducer for mechanical damage.
 Familiarize yourself with the articulation controls.
 Ensure that the transducer has been properly cleaned and has been high-level disinfected,
if disinfection is necessary.
 Perform a leakage current test on the transducer. Refer to the manufacturer's instructions
included with the tester.
 Place a sheath on the transducer, if indicated.
 If necessary, place a drape over the transducer handle, cable, connector and the
ultrasound system.
