Selecting Balloon Size and Type

Upon connection of the Balloon Extension Tubing the ventilator will display the Esophageal Balloon Size and
Type dialogue box. You must select the size and type of balloon you intend to use before you will be able to
conduct the Balloon Test.
Note:
Disconnecting the Balloon Extension Tubing will require you to select balloon size and type and repeat the
balloon test procedure.
In order to change balloon size or type you must disconnect and re-connect the balloon extension tubing to
open the Esophageal Balloon Size and Type dialogue box.
Selecting a balloon size and type other than the one to be used can result in failure of the balloon test.

Balloon Leak / Size Test

The Balloon Test verifies the integrity and size of the balloon catheter. The ventilator will display a Pass or Fail
message in the message bar at the bottom of the screen.
If the Balloon Test is not passed all connections should be checked to assure they are secure and balloon
integrity should be evaluated.
Note:
The Balloon Test must be performed without the balloon in the patient
