Most important indicator that a patient Tachypnea
has a severe illness?
Hypoxemic (PaO2 <50-60)
3 respiratory types, and their criteria Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
Difference in AG from normal - Difference in HCO3 from normal
Delta gap (formula, when and why it's In AG metabolic acidosis it's used. It tells you if there's underlying metab
used) alkalosis or respiratory acidosis with bicarb compensation IN ADDITION
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, what it 1.5[HCO3] + 8 +/- 2
measures) If compensation is adequate in acid/base issues
How AG changes with albumin Decreases 2.5-3 for every 1 decrease in albumin

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