FCCS Post Test Exam Questions And Well
Elaborated Solutions
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.
Winter's formula (equation, what it measures) - answers 1.5[HCO3] + 8 +/- 2
If compensation is adequate in acid/base issues
How AG changes with albumin changes - answers Decreases 2.5-3 for every 1 decrease in
albumin
Hemodynamic changes after intubation - answers Hypo/hypertension
Arrhythmia
Tachycardia
Pressure support equation for BiPAP - answers IPAP - EPAP
3 types of vent cycles - answers Volume (preset tidal volume, relieves WOB the most)
Time (constant pressure of time)
Flow (constant pressure until inspiratory flow is below 25% of peak)
Goal tidal volume - answers 10 cc/kg
Goal FiO2 on vent - answers Start at 1.0, then decrease as SpO2 tolerates (goal of 92-94
saturation)
Ppeak - answers Peak inspiratory pressure
Pplat (try to keep it below ?) - answers Inspiratory plateau pressure (shows alveolar distention)
30
AutoPEEP (what it is, what it causes, how to fix it) - answers 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)
Danger of increased PEEP - answers Increases autoPEEP, increases Pplat
PaO2 we're usually happy with - answers >60
When to consider NPPV vs invasive - answers When it's a quickly solved problem in 1-2 days
(e.g. COPD exacerbation)
