Airway Management

Patent Airway Open Airway
Structures of the Airway nose, mouth, pharynx, larynx, trachea, bronchi, lungs
Structures posterior and inferior to the mouth&nasal passageways oropharynx, nasopharynx, laryngopharynx (entrance to trachea)
Laryngopharynx/ hypopharynx point between upper and lower airways. provides structure and protects opening of the trachea
larynx protected by the superior epiglottis, at the the glottic opening
trachea tube protected by 16 rings of cartilage, anterior to esophagus, inferior to thyroid cartilage and larynx, protected by cricoid cartilage.
cricoid cartilage protects the superior part of trachea 360 degrees around, the other rings are 3/4s around
Mainstem Bronchi Bifurcated part of the trachea that starts at the carina
diffusion movement of gases from high concentration to low concentration
Region that the lungs, bronchioles and alveolis cover from the clavicles to the diaphragm
Common obstruction with decreased mental status loss of muscle tone results in the tongue relax+fall back which causes the epiglottis to fall back and cover the trachea
Acute Airway Obstruction now by foreign body, choking
Chronic Airway Obstruction 3 months or longer, ie. mucus
bronchoconstriction when smooth muscle contracts and decreases the internal diameter of the airway, fand increases resistance to airflow ie. asthma
stridor a high-pitched sound generated from partially obstructed airflow in the upper airway
sniffing position bolt upright position with head pitched forward like to sniff something.
sounds of obstructed air movememt stridor, snoring, gurgling, gasping
jaw-thrust maneuver used to correct blockage of the airway by moving the jaw forward without tilting the head and neck, ONLY HEAD, NECK, SPINAL
head-tilt chin-lift maneuver used to correct blockage of the airway by the tongue and tissues connected (epiglottis) by tilting head back and lifting the chin NEVER HEAD NECK SPINAL
OPA oropharyngeal airway inserted in the mouth to help properly position the tongue
NPA nasopharyngeal airway inserted in the nasal that rests in the pharynx and also helps properly position the tongue. Lube with water-based lubricant
gag reflec swallowing or retching that occurs when something is placed in the back of the pharynx
cerebrospinal fluid clear fluid from the nose or ears indicating a skull fracture and that an NPA should not be used
Suction Devices must have at least 30 liters/min of suction at opening of collection tube, which will occur if the vacuum generates no less than 300mm Hg
Yankauer the rigid pharyngeal tip for suction
Techniques of Suctioning 1) Always use the appropriate infection control practices 2) Limit suctioning to no longer than 10 seconds at a time 3) place the tip/catheter where you want to begin suctioning and suction on the way out
