Home sleep testing for the diagnosis of pediatric obstructive sleep apnea: the times they are a changing...!

Abstract

The current paradigm shift in the diagnosis of sleep apnea in adults has further emphasized the urgent need for the development and validation of less inconvenient and laborious approaches than the in-laboratory nocturnal polysomnography for evaluation of children. These efforts have been primarily centered around the following: first, refinements and validation of questionnaires; second, single-channel recordings such as oximetry, airflow, or ECG; third, home-based polysomnography and polygraphy; and fourth, biomarkers. The major overall findings emanating from such studies indicate that none of the approaches provides an ideal substitute to in-laboratory nocturnal polysomnography. Conversely, many of the proposed approaches enable effective screening in a cost-effective manner, and may be particularly suitable when access to pediatric sleep medicine facilities is limited or unavailable. The overall improvements in technologies and in our understanding of pediatric sleep-disordered breathing should enable population-tailored effective home-based diagnostic approaches that reduce the overall burden to the family, while achieving high levels of diagnostic accuracy. Newer algorithms will have to be developed and validated to allow for effective implementation of such approaches.
