Medical gas cylinder colors Correct answer-Blue- Nitrous Oxide
Green- Oxygen
Yellow- Compressed Air
Brown- Helium
Black- Nitrogen
Gray- Carbon Dioxide
Airway Adjuncts(8) Correct answer-Head-tilt/Chin-lift
Tongue traction suture
Nasopharyngeal airway
Oropharyngeal airway
Laryngeal mask airway
I-gel supraglottic airway
Endotracheal tube
Combitube
Cricothyrotomy
Tongue traction suture Correct answer-When the tongue is obstructing the airway one or two sutures
can be placed through the dorsum of the tongue and grasped with a large hemostat
Nasopharyngeal airway Correct answer-Does not interfere with procedures
Well-tolerated
Can be used on awake patients
Passed through one of the nostrils into the nasal cavity into the oropharynx posterior to the tongue.
Oropharyngeal airway Correct answer-Oral airway
may be used to position the tongue in a more anterior position
interferes with intraoral procedures
not tolerated well in awake patients
Supraglottic airway Correct answer-Placed above the level of the vocal cords
2 types: laryngeal mask airway (LMA) and I-gel supraglottic airway
Gastric port or small tube that passes through the length of the airway to allow access for a suction
catheter that can by used to remove fluid in the stomach and diminish likelihood of aspiration of acidic
gastric juices.
Laryngeal mask airway (LMA) Correct answer-Plastic tube at the end of which is a small air inflated
