Cleaning the Esophagus (TEE/TOE Models)
If you encounter reduced quality of the echocardiographic image after extensive use, it may be necessary
to clean the esophagus with the liquid soap/water mixture.
To clean the esophagus:
1. Place the training model in a moderate Trendelenburg position. This positions the head and
neck lower than the torso to help with the draining of fluid during cleaning.
Moderate Trendelenburg Position
2. Apply the 1:1 water and soap mixture to a clean soft cloth.
3. Clean the mouth to remove any visible dried gel. The dried gel looks like a fine powder.
4. Fill the soap mixture into a syringe with tubing attached.
5. Put the tubing into the model’s throat and infuse the soap mixture through the tube into the
esophagus.
6. Flush the esophagus and throat with the soap mixture and allow the fluid to flow back down into
the mouth.
7. To remove the returned fluid from the mouth, aspirate it with the syringe and tubing.
8. Repeat steps 4-7. You will have flushed the esophagus and throat two times.
9. Leave the model in the Trendelenburg position and let it dry. Drying time is approximately three
(3) hours at room temperature.

Fluid Overfill
You can overfill fluid spaces and vessels if you inject too much fluid. Overfill does not usually result in
permanent damage, but you should correct it as soon as possible.
