Nasal Cannula Adjustments

The lower prongs of the nasal cannula should rest just in front of your upper lip to measure airflow from your mouth.

If the prongs are too long and extend past your lower lip, you may trim the ends with scissors as shown.

Place the cannula underneath your nose with the shorter pair of prongs resting under your nostrils. The longer prongs will curve slightly in towards your mouth.

The headband fits around your head and over the ears. Pull on the ends of the band to adjust the fit of the cannula.
