what is the use of 3%hypertonic saline in nèbulizer for bronchitis in infants

A. Babies with severe breathing difficulty due to cold or cough, nebulisation is a good option. Nebulisation with saline solution can thus help clean congestion in babies, helping them to breathe better. And never use any medicated solution unless your doctor has advised for it. Always use saline water for minor ailments like cough, cold, season change etc.
