How are nasal prongs/cannulas utilized in oxygen delivery?

• A. They cover the mouth and nose
• B. They are inserted into the ears
• C. They are placed in the nares
• D. They connect directly to the intubation tube

Answer: (C)

Nasal prongs deliver oxygen by sitting inside the nostrils, in the nares. The small outlets point toward the nasal passages so the oxygen flows directly into the nose and mixes with the inhaled air, supplying the lungs with a controlled amount of oxygen. This method is ideal for patients who need supplemental oxygen but not a high concentration or a sealed mask, and it allows them to breathe comfortably, speak, and eat. It isn’t used by placing anything over the mouth and nose like a mask, it isn’t inserted into the ears, and it isn’t connected to an intubation tube. The prongs in the nares are the essential feature that makes this delivery system work.
