DAANCE Module 3
Purpose of the scavenging system - ✔✔Reducing the levels of the noxious agents to an acceptably low
level by exhausting them outside the operating room.
Medical gas cylinder colors - ✔✔Blue- Nitrous Oxide
Green- Oxygen
Yellow- Compressed Air
Brown- Helium
Black- Nitrogen
Gray- Carbon Dioxide
Airway Adjuncts(8) - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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) - ✔✔Plastic tube at the end of which is a small air inflated balloon that sits
tightly over the top of the larynx.
Advantage: may be placed blindly without the use of a laryngoscope.
Does NOT protect the airway from the aspiration of regurgitated material.
Follows the natural bend of the oropharynxa nd comes to rest over the larynx. →cuff is then inflated
I-gel Supraglottic airway - ✔✔Similiar to LMA, however, balloon is filled with gel rather than air, which
enables the mask to adapt closely to the tissues surrounding the larynx and does not require inflation.
These airways can be rapidly inserted, and they are less likely to become dislodged.
Endotracheal Tubes - ✔✔May be placed blindly orally, nasally or in tracheostomy site
End of the tube passes through the vocal cords, after which it is advanced to terminate halfway between
the vocal cords and bifurcation of the trachea.
Important to auscultate the left and right side of the chest as well as the stomach. Breath sounds should
be heard on both sides of the chest
Combitube - ✔✔Reserved for significant emergencies
Can be placed blindly
It will ordinarily (80%) of the time end up in the esophagus after blind placement.
Both cuffs are inflated, can be ventilated through the esophagus or trachea
