Sleep Apnea

Sleep disordered breathing (SDB) is associated with many childhood diseases. Children with obesity or neuromuscular disease, for example, may develop hypoventilation from weak or overloaded respiratory muscles, compromising airway patency and/or gas exchange during sleep. Children with mood disorders and hypertension may also have a higher incidence of disordered sleep compared to others in the general population. The research agenda of this team is to determine the prevalence of sleep disordered breathing and assistive technologies in chronic disease states, to study diagnostic tools and predictors of sleep-disordered breathing, and to evaluate the benefits and consequences of treatment from a multi-disciplinary perspective. Treatment of the sleep disordered breathing alongside the underlying condition must be considered in development of a management plan and the consequences and benefits of this treatment then can thus be better understood.
