Airway and CV Assessment Flashcards
Describe airway management of unconscious patient with respiratory effort
high flow O2, check for obstruction, insert naso or oropharyngeal AW
How much O2 is delivered with a non-rebreather mask?
nearly 100%
Usually better tolerated in conscious patients. Can usually be used even with intact gag reflex
nasopharyngeal airways
How do you determine appropriate diameter of nasopharyngeal airway?
Outer diameter of the NPA should not be larger than the inner diameter of the nares
How do you determine appropriate length of nasopharyngeal airway?
Length should not be longer than from the tip of the patient’s nose to the earlobe
For unconscious patients. Will often lead to emesis if gag is intact. Needs to be inserted carefully so that tongue is not pushed back therefore blocking the airway
oropharyngeal airway
How do you determine proper size of oropharyngeal airway?
stretches from the mouth to the angle of the mandible
Good alternative to continued bag-mask ventilation. Rescue device after failed intubation
LMA
What are CI to LMAs?
Cannot open mouth or complete upper airway obstruction
Rapidly acting sedative (ie, induction) agent and a neuromuscular blocking (ie, paralytic) agent. minimize risk of aspiration of stomach contents
Rapid Sequence Intubation (RSI)
May be contraindicated with a difficult airway
paralytic agent
Administration of high flow oxygen prior to intubation. Have patient take 8 vital capacity breaths with O2 if able
preoxygenation
for peds to prevent vagal response (severe bradycardia) in pretreatment phase of intubation
atropine
may decrease the sympathetic response to intubation in adults (3 mcg/kg IV) do not use in pt’s with low BP
opioids (fentanyl)
Name the common neuromuscular blocking agents used for intubation
succinylcholine, vecuronium, rocuronium
