Bubble Continuous Positive Airway Pressure(CPAP) is a gentle and non-invasive ventilation respiratory intervention for newborns designed with wide-bore tubing and a low-resistance interface, that is associated with the least damage to the developing premature lung, the least incidence of chronic lung disease and the best long-term pulmonary outcomes among preterm infants. It is proven to be safe, effective and can help avoiding intubation and mechanical ventilation when used immediately.
