Lab exam 1 Flashcards
2 types of Oropharyngeal airways
Berman and Guedel
Has a single center channel
Guedel
Has a 2 sided channel
Berman
How do you measure an oropharyngeal airway?
Measure from corner of pt’s mouth to angle of the jaw
If an Oropharyngeal airway is to large it can push……. leading to an obstruction
the epiglottis against the larynx, leading to obstruction
If Oropharyngeal airway is to small it may not
clear the tongue above the epiglottis against the larynx
Another name for Nasopharyngeal
- nasal trumpet
- nasal horn
Indications for Nasal airway (2)
- facilitate ventilation
- Removal of secretions by nasotracheal suctioning
Nasopharyngeal airways sizes. Female and male
Female: 6
Male:7
If nasopharyngeal airway is to short it cannot separate
soft plate from posterior wall of pharynx
If nasopharyngeal airway is to long it may enter
the larynx, causing laryngeal reflexes or enter the space between the epiglottis and vallecular
How do you measure a nasalphargeal airway?
from pt’s earlobe to tip of the nose
How do you inset a nasalpharengeal airway?
parallel to the nose floor, beveled edge to the septum
Oropharyngeal airways should be restricted to
unconscious pts to avoid gagging and regurgitation
Esophageal Obturator Airway (EOA) is inserted into the
esophagus
Laryngeal Mask Airway (LMA) provides a seal over the…..
With a max cuff pressure of
larynx; 60 cmH2O
LMA does not protect the
airway from aspiration
LMA is what kind of a insertion?
Blind
Parts of an ET tube
- Pt end
- Murphy eye
- High volume, low pressure cuff
- Internal diameter
- Distance in mm
- Pilot ballon
- Connection to breathing circuit
- Inflation valve
- Machine end
- Radiopaque line
Esophageal-Tracheal Combitube (ETC) is also called ___________ - ____________ airway
Double-Lumen airway
ETC is what kind of insertion
Blind
ETC may be inserted into the
esophagus or trachea
ETC has 2 cuffs
- Distal cuff
- Proximal cuff
Double- Lumen Endotracheal Tube (DLT) indications (3)
- Lung isolation
- prevent lung to lung spillage
- surgical procedure on non ventilated lung
