A patient who requires supplemental oxygen at 40% has a variable respiratory pattern. Which of the following devices would most reliably provide a consistent oxygen concentration?
A. nasal cannula
B. air-entrainment mask
C. face tent
D. nonrebreather mask
Answer: B. For a patient who has a variable inspiratory requirement, and therefore breathes with a variable respiratory pattern, oxygen delivery through an air-entrainment device is more appropriate. Air-entrainment systems provide high flow and are more capable of meeting and/or exceeding the patient's inspiratory demand and spite of variability in the respiratory pattern.
