So consecutive cases followed between 2013 and 2015, about a quarter much of what we do as clinicians is geared to making a diagnosis and could be weaned safely for underlying conditions of upper airway initiating treatment. As a result, maintaining the status quo is often anomalies, Prader Willi Syndrome or bronchopulmonary dysplasia. favoured over consciously winding back therapy to what may be needed.

Nonetheless, using non-invasive support is the world to move toward building evidence for standardizing practice probably much like other prescribed therapies for children with chronic for the weaning of CPAP and non-invasive support in children. conditions like asthma or cystic fibrosis, where we know that adherence with chronic therapies sit well below our expectations.2,3 Previous studies of “adequate” (4 h per night) adherence with non-invasive therapies in children with chronic conditions such as neuromuscular ORCID Dominic A.
