1. Most important indica- Tachypnea
tor that a patient has a
severe illness?
2. 3 respiratory types, Hypoxemic (PaO2 <50-60)
and their criteria Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
3. Delta gap (formula, Difference in AG from normal - Difference in HCO3 from normal
when and why it's
used) In AG metabolic acidosis it's used. It tells you if there's underlying metabolic
alkalosis or respiratory acidosis 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.
4. Winter's formula 1.5[HCO3] + 8 +/- 2
(equation, what it If compensation is adequate in acid/base issues
measures)
5. How AG changes with Decreases 2.5-3 for every 1 decrease in albumin
albumin changes
6. Hemodynamic Hypo/hypertension
changes after Arrhythmia
intubation Tachycardia
7. Pressure support IPAP - EPAP
equation for BiPAP
8. 3 types of vent cycles Volume (preset tidal volume, relieves WOB the most)
Time (constant pressure of time)
Flow (constant pressure until inspiratory flow is below 25% of peak)
9. Goal tidal volume 10 cc/kg

10. Goal FiO2 on vent Start at 1.0, then decrease as SpO2 tolerates (goal of 92-94 saturation)
11. Ppeak Peak inspiratory pressure
12. Pplat (try to keep it be- Inspiratory plateau pressure (shows alveolar distention)
low ?) 30
13. AutoPEEP (what it is, Breath stacking
what it causes, how to Decreases preload to the heart with positive pressure on the lungs -->
fix it) hypotension
Decrease RR, decrease inspiration time (goal is to have more time for the
lungs to exhale)
14. Danger of increased Increases autoPEEP, increases Pplat
PEEP
15. PaO2 we're usually >60
happy with
16. When to consider When it's a quickly solved problem in 1-2 days (e.g. COPD exacerbation)
NPPV vs invasive When the patient can be compliant with working with NPPV
17. When to consider If things aren't really improving in a matter of hours
switching from NPPV If your therapeutic goals haven't been met in 4-6 hours
to invasive ventilation
support
18. Manual decompres- If patient is air trapping like crazy on the vent, and you disconnect it and
sion (when you use it) push up on the patients diaphragm to get everything out
19. What a high A-a gradi- V/Q mismatch
ent means
