Examination 3-1
CHAPTER 3
Examination
While echocardiographs from the transesophageal or transgastric position provide
important clinical data not available from any other view, the examining physician must
consider a number of conditions when selecting a patient for safe use of the transducer.
The list of contraindications and considerations do not constitute a complete list of all
possible factors the examining physician must consider before starting the examination.
They are presented only as examples. See “Contraindications” on page 2-2.
Pre-exam inspection
It is important to establish and use a check-out procedure to ensure that the transducer is
safe to use and functions properly prior to each use. If you observe or suspect any
irregularity, substandard functioning, or unsafe condition, do not use the TEExi transducer.
Call FUJIFILM SonoSite or your local representative immediately.
Perform the following before each exam:

Visual tactile inspection. See “To visually and tactilely inspect the transducer” on
page 2-6.

Tip deflection inspection. See “To inspect Tip Deflection” on page 2-8.

Brake inspection. See “To inspect the tip deflection brake” on page 2-9.

Scan plane rotation inspection. See “To inspect scan plane rotation” on page 2-11.

Leakage test or bite-hole inspection test. See “Electrical leakage testing” on
page 5-5 or “Bite hole detection” on page 5-6.
WARNINGS

To avoid trauma to the patient’s stomach or esophagus, do not
use excessive force during insertion, positioning, or
withdrawal.

To prevent damage to the patient’s esophagus when inserting
or withdrawing the transducer, the control wheel must be in
the freely moving, neutral, and unlocked state. See
Figure 2-6 on page 2-9.
