Question:
3 respiratory types, and their criteria
Answer:
Hypoxemic (PaO2 <50- 60) Hypercapnic (PaCO2 >50, pH <7.36) Mixed
Question:
Delta gap (formula, when and why it's used)
Answer:
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.
Question:
Winter's formula (equation, what it measures)
Answer:
1.5[HCO3] + 8 +/- 2 If compensation is adequate in acid/base issues
Question:
How AG changes with albumin changes
Answer:
Decreases 2.5-3 for every 1 decrease in albumin
Question:
Hemodynamic changes after intubation
Answer:
Hypo/hypertension Arrhythmia Tachycardia
, Question:
Pressure support equation for BiPAP
Answer:
IPAP-EPAP
Question:
3 types of vent cycles
Answer:
Volume (preset tidal volume, relieves WOB the most) Time (constant pressure of time)
Flow (constant pressure until inspiratory flow is below 25% of peak)
Question:
Goal tidal volume
Answer:
10 cc/kg
Question:
Goal FiO2 on vent
Answer:
Start at 1.0, then decrease as SpO2 tolerates (goal of 92-94 saturation)
Question:
Ppeak
Answer:
Peak inspiratory pressure
Question:
Pplat (try to keep it below ?)
Answer:
Inspiratory plateau pressure (shows alveolar distention) 30
