Q

When inserting a Combitube how would you know that you inserted a tube into the esophagus or the trachea?

A

Ventilating from the blue or the first port causes a chest rise and breath sounds indicates you inserted the tube into the esophagus.
- if not ventilate on the second port and recheck for breath sounds because it looks like you into intubated the trachea
