1. Most important indicator that a patient has a severe illness?: Tachypnea
2. 3 respiratory types, and their criteria: Hypoxemic (PaO2 <50-60)
Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
3. Delta gap (formula, when and why it's used): Difference in AG from normal - Difference in
HCO3 from normal
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 (equation, what it measures): 1.5[HCO3] + 8 +/- 2
If compensation is adequate in acid/base issues
5. How AG changes with albumin changes: Decreases 2.5-3 for every 1 decrease in albumin
6. Hemodynamic changes after intubation: Hypo/hypertension
Arrhythmia
Tachycardia
7. Pressure support equation for BiPAP: IPAP - EPAP
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 below ?): Inspiratory plateau pressure (shows alveolar distention)
30
13. AutoPEEP (what it is, what it causes, how to fix it): Breath stacking
Decreases preload to the heart with positive pressure on the lungs --> hypotension
Decrease RR, decrease inspiration time (goal is to have more time for the lungs to exhale)
14. Danger of increased PEEP: Increases autoPEEP, increases Pplat
15. PaO2 we're usually happy with: >60
1/4
