COMPLETE REAL EXAMQUESTIONS AND CORRECT
ANSWERS|ACTUAL EXAM| ACCURATE SOLUTIONS
WITH RATIONALES/ALREADY GRADED A+
Double-Lumen ET tube - ANSWER --Endobronchial/Carlen's tube
-can ventilate one lung separately
-two cuffs: distal cuff is high pressure, low volume for mainstem
bronchus tube
-during pneumonectomies, lobectomies
-for bronchopleural fistulas etc
Esophageal Tracheal Combitube - ANSWER --for emergency
airway management
-if placed in trachea, distal balloon will seal trachea(ET tube) and
clear #2 is used for ventilation
-if placed in esophagus, distal balloon will occlude esophagus
-ventilation will be provided through blue #2 longer tube
Laryngeal Mask Airway (LMA) - ANSWER --positioned
directly over trachea (hypopharynx)
-standard ET tube can be inserted directly
through LMA into the trachea
,-short term
ventilation
Hi-Lo Evac Tubes - ANSWER --for Continuous
Aspiration of Subglottic Secretions (CASS)
-continuous suction via separate
pilot tube @ 20 mmHg
-reduce
VAP
Extubation - ANSWER -
-inspire deeply
-remove tube at PEAK INSPIRATION to
prevent vocal cord damage
MARKED distress/stridor = reintubate
moderate stridor = O2-Cool Mist-
Racemic epinephrine mild stridor =
humidity, O2, Racemic epinephrine
Tracheostomy - ANSWER --for long term ventilation
-cuff should be inflated when eating & PPV
-if obsructed = pass catheter, remove tube, ventilate and insert
new tube
-clean with hydrogen peroxide
,Fenestrated tube - ANSWER -
-Used for weaning
-not for codes or
emergencies
-when plugging the tube, deflate cuff, remove the inner
cannula and then plug the trach tube
