Double-Lumen Airways Flashcards
WHAT AM I?
I have two external openings, two lumens, two pilot balloons, two cuffs (yellow and white) & two black lines for depth indication
Placed while in neutral position
Combitube
Combitube ml of air in Proximal and Distal cuff
P. 85-100ml
D. 12-15ml
How many apertures does a combitube have?
8 ventilation apertures
Why would you ventilate through the blue longer tube?
Meaning that the distal tip is in the esophagus
leaving clear tube for gastric suctioning
Why would you ventilate through the clear shorter tube?
Meaning that the distal tip is in the trachea
leaving blue tube useless
