Question 7

oxygen
special considerations

Answer 7

● Patients with carbon monoxide poisoning may be hypoxemic with severe respiratory
distress despite SpO2 of 100% due to carbon monoxide’s much higher affinity for
hemoglobin and subsequent displacement of O2.
● Use with caution on neonates as oxygen toxicity may occur.
● High-flow O2 may decrease respiratory drive in COPD patients (rare)
