Echo bronchoscope: balloon placement and inflation
-A disposable latex balloon is placed over the US probe.
-The balloon is inflated with sterile water and provides a fluid interface between the probe and the tracheal wall. A 20 cc syringe filled with sterile water is attached to the balloon channel of the bronchoscope. While inflating the balloon, the syringe faces downwards and the US transducer upwards.
-Trapped air should be evacuated from the balloon by applying pressure to the distal circular lip of the balloon with the tip of a gloved finger.
-The ballon is sealed in place and silicone spray is used to lubricate the bronchoscope.
