NMNC 4510 Exam #1 questions well
answered graded A+
PaO2 normal range?
SaO2 normal range? - correct answer ✔✔PaO2: 80-100 mmHg
SaO2: > 95%
Hypoxemia? - correct answer ✔✔PaO2 <60 if pt is on 60% or greater oxygen
already.
Hypercapnia? (2) - correct answer ✔✔- PaCO2 >45 and pH <7.35
- metabolic acidosis is hypercapnia
Causes of hypoxemic respiratory failure? (4) - correct answer ✔✔- V/Q mismatch
- shunt: air and blood are not touching and there is no exchange (PNA)
- diffusion limitation (ex. COPD)
- alveolar hypoventilation
Hypoxic Problem:
Patent foramen ovale? (2) - correct answer ✔✔- deoxygenated blood is mixing w/
