Continuous Positive Airway Pressure (CPAP) is an effective treatment option for children with Obstructive Sleep Apnea (OSA). CPAP delivers a steady stream of air through a mask worn over the nose or face. The air gently blows into the back of the throat, keeping the airway open so your child can easily breathe during sleep. Bilevel Positive Airway Pressure (BiPAP) is an effective treatment option for children with Chronic Obstructive Pulmonary Disease (COPD), Congestive Heart Failure (CHF), or poor breathing due to other medical conditions. BiPAP blows air into the lungs while breathing in, and a reduced amount of air into the lungs when breathing out.
