FLO Baby Saline Nasal Spray Mechanism of Action

The nasal passages in a baby's nose are very small and easily blocked with excess mucus.
Mucus is naturally produced in the nose and its role is to trap foreign particles such as dust, pollens and bacteria to help prevent them from entering the lungs. Mucus is also needed to protect the delicate nasal linings from drying out. The nose has a mucus transport system (this is made up of microscopic hairs called cilia) and it moves mucus from the front of the nose to the back of the throat from where it is then swallowed.
It is only when mucus is produced in excessive amounts that it becomes a problem. Most commonly, excess mucus is produced by the nasal lining in response to viral infections (colds) and allergy. Clearing the baby's nose of excess mucus helps baby breathe more easily resulting in better feeding and sleeping.
