FCCS Exam Questions and Answers2023/2024
Most important indicator that a patient has a severe illness? - -Tachypnea
-3 respiratory types, and their criteria - -Hypoxemic (PaO2 <50-60)
Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
-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.
-Winter's formula (equation, what it measures) - -1.5[HCO3] + 8 +/- 2
If compensation is adequate in acid/base issues
-How AG changes with albumin changes - -Decreases 2.5-3 for every 1
decrease in albumin
-Hemodynamic changes after intubation - -Hypo/hypertension
Arrhythmia
Tachycardia
-Pressure support equation for BiPAP - -IPAP - EPAP
-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)
-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
-Pplat (try to keep it below ?) - -Inspiratory plateau pressure (shows alveolar
distention)
