factors that cause ventilator induced lung injury - ANSWER: too much volume
too much pressure
o2 toxicity
variables that affect oxygenation - ANSWER: FiO2
PEEP
Mean airway pressure
variables that affect ventilation (paCO2) - ANSWER: RR
tidal volume
(things that would blow off CO2)
plateau pressure of vent - ANSWER: do an inspiratory pause
reflects alveolar pressure
should be < 30 (?)
peak airway pressure really high (50), but plateau pressure normal ... - ANSWER:
large airway obstruction
bronchospasm
peak airway pressure of 50, plateau pressure high (40)... - ANSWER: alveolar lung
disease (restrictive)
ARDS
Peak airway pressure - ANSWER: reflects large airway pressure
should be < 40
RR x tidal volume - ANSWER: minute ventilation
assist control / continuous mandatory ventilation - ANSWER: set rate and volume
(volume control)
patient triggered breath > they get full volume
, barotrauma, stacking, hyperventilation
pressure control - ANSWER: set peak pressure, get whatever tidal volume
supports every breath
limits barotrauma, but can have inadequate ventilation (esp if developing ARDS)
SIMV -synchronized intermittent mandatory ventilation - ANSWER: set volume.
spontaneous breath does not get full tidal volume, tries to syncronize
criteria for extubation - ANSWER: neuro intact / protect airway
vent settings minimal - PEEP<10, FiO2 <50
Rapid Shallow Breathing Index (RSBI) - ANSWER: RR / Tidal volume
<100 -> good chance of predicting extubating
Negative Inspiratory Force (NIF) - ANSWER: predictor of who will fail extubation -
expiratory hold that gives sense of muscle strenth in chest
need > 20
ARDS lung protection - ANSWER: low tidal volumes (4-6 cc/kilo)
allow permissive hypercapnea as long as PO2 fine, pH>7.2
ARDS salvage therapies (2 - proven) - ANSWER: paralytics
proning
APRV (airway pressure release ventilation) - ANSWER: high pressure to keep alveoli
open, and then release
septic shock - ANSWER: need pressors for MAPs > 65
AND
have lactate > 2 after rescuscitation
Sepsis management - ANSWER: early goal directed rescuscitation:
w/i 3h: cx, abx, boluses at 30 cc/kilo for lactate
w/i 6 hours: pressors
Alpha 1 receptors - ANSWER: vasoconstriction
