FCCS Post Test Review questions ACTUAL UPDATED QUESTIONS AND
CORRECT ANSWERS
Most important indicator that a patient has a severe Tachypnea
illness?
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)
30
