Final answer:
Nasal cannulas and face masks can deliver equal amounts of FiO2.
Step-by-step explanation:
Nasal cannulas and face masks can deliver equal amounts of FiO2. Both nasal cannulas and face masks are devices used to administer supplemental oxygen to patients who have difficulty breathing on their own. The key difference between the two is the way oxygen is delivered: nasal cannulas deliver oxygen directly into the nostrils, while face masks cover the nose and mouth to deliver oxygen.
