How do you insert a cannula properly in the nose?

To insert a cannula properly in the nose, first ensure that you have a clean, sterile cannula and that the patient is in a comfortable position. Gently insert the prongs of the cannula into the nostrils, with the prongs pointing downward and slightly toward the back of the throat. Ensure a snug fit without causing discomfort, and adjust the ear loops to secure the cannula in place. Finally, check that the cannula is functioning properly and that oxygen flow is adequate if applicable.
