<unk>  is a non-invasive ventilation strategy for newborns with infant respiratory distress syndrome (IRDS). It is one of the methods by which continuous positive airway pressure <unk>  is delivered to a spontaneously breathing newborn to maintain lung volumes during expiration. With this method, blended and humidified oxygen is delivered via short binasal prongs or a nasal mask and pressure in the circuit is maintained by immersing the distal end of the expiratory tubing in water. The depth to which the tubing is immersed underwater determines the pressure generated in the airways of the infant. As the gas flows through the system, it<unk> s” out and prevents buildup of excess pressures.<unk>  is appealing because of its simplicity and low cost. It is also associated with a decreased incidence of bronchopulmonary dysplasia (BPD) compared to mechanical ventilation. Not all infants with IRDS are candidates for initial treatment with<unk>  and not all those who are given<unk>  can be successfully managed with this modality.
