Nasal Cannula: Gentle Oxygen Support Through Your Baby’s Nose

What Is a Nasal Cannula?

A nasal cannula is a small, soft tube with two tiny prongs that rest just inside your baby’s nose. It can be used to provide extra oxygen or breathing support while allowing your baby to breathe on their own.

You may hear your NICU team talk about your baby’s flow rate and FiO₂ (oxygen concentration). These settings tell the care team how much flow and oxygen your baby is receiving and can be adjusted as your baby’s needs change.

Why Does My Baby Need One?

A nasal cannula may be used when a baby needs some extra oxygen or breathing support but does not need more intensive respiratory support, such as CPAP or a ventilator.

For some babies, moving to a nasal cannula is an exciting step as they need less breathing support. Other babies may start with a nasal cannula depending on their individual needs.

What Can Parents Expect?

Because the cannula sits at the nose rather than covering much of your baby’s face, it may make it easier to see your baby’s face and participate in activities such as skin-to-skin care and holding when your NICU team says it is safe.

Your baby's oxygen needs may change from day to day—or even throughout the day. This is common in the NICU, and the care team will adjust support based on your baby's breathing, oxygen levels and overall condition.

Remember: Every baby’s respiratory journey is different. Needing more or less support at different times does not necessarily mean your baby is moving backward or forward—it means the NICU team is responding to what your baby needs.
