How are nasal prongs/cannulas utilized in oxygen delivery?

Nasal prongs or cannulas are designed specifically for delivering supplemental oxygen through the nostrils. This method allows for a comfortable and non-invasive way to increase oxygen flow to patients who may have difficulty breathing or require additional oxygen support.

When nasal prongs are placed in the nares, they ensure that oxygen is delivered directly to the respiratory system efficiently. The prongs fit snugly into the nostrils, allowing for the inhalation of oxygen-enriched air while still permitting patients to talk, eat, or breathe normally through their mouths if needed.

This delivery method is particularly useful in various clinical settings, as it offers a less cumbersome option compared to other forms of oxygen supplementation, such as masks or intubation. In contrast, other options mentioned do not accurately describe the function or placement of nasal prongs in oxygen therapy.
