When, where and how to test for sleep apnea.

This presentation focused on issues relevant to the decision to perform testing for sleep disordered breathing. Polysomnographic signals can be captured equally well in both the center and in the home, by attended as well as unattended monitoring. Attention now is on clinical decisions that best match patient presentation to improved clinical outcome. Standardization interpretation can be achieved, provided sufficient experience, training, and continued surveillance of equipment function. The sleep center must evolve to manage patient with more diverse presentations and be a resource for knowledge in sleep and chronobiology to a broad range of medical issues and systems.
