Most important indicator Tachypnea
that a patient has a severe
illness?
Hypoxemic (PaO2 <50-60)
c Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
Difference in AG from normal - Difference in HCO3
from normal
In AG metabolic acidosis it's used. It tells you if there's
Delta gap (formula, when
underlying metabolic alkalosis or respiratory acidosis
and why it's used)
with bicarb compensation IN ADDITION to the AG
metabolic acidosis. Both of those would result in a
high bicarb to begin with, and a smaller change in
bicarb from normal.
Winter's formula (equation, 1.5[HCO3] + 8 +/- 2
what it measures) If compensation is adequate in acid/base issues
How AG changes with Decreases 2.5-3 for every 1 decrease in albumin
albumin changes
Hypo/hypertension
Hemodynamic changes
Arrhythmia

Pressure support equation IPAP - EPAP
for BiPAP
Volume (preset tidal volume, relieves WOB the most)
Time (constant pressure of time)
3 types of vent cycles
Flow (constant pressure until inspiratory flow is below
25% of peak)
Goal tidal volume 10 cc/kg
Start at 1.0, then decrease as SpO2 tolerates (goal of
Goal FiO2 on vent
92-94 saturation)
Ppeak Peak inspiratory pressure
Inspiratory plateau pressure (shows alveolar
Pplat (try to keep it below
distention)
?)
30
Breath stacking
Decreases preload to the heart with positive pressure
AutoPEEP (what it is, what
on the lungs --> hypotension
it causes, how to fix it)
Decrease RR, decrease inspiration time (goal is to
have more time for the lungs to exhale)
Danger of increased PEEP Increases autoPEEP, increases Pplat
PaO2 we're usually happy >60

When it's a quickly solved problem in 1-2 days (e.g.
When to consider NPPV vs COPD exacerbation)
