Immediate consequences of respiratory events in sleep disordered breathing

Conclusion: No single consequence occurred after every event; thus none can be used to corroborate airflow reduction as non-artifactual without missing events corroborated by other consequences. As different consequences validate non-hierarchical sets of respiratory events, we propose there is need to capture all changes in breathing in obstructive sleep apnea/hypopnea syndrome before examining their role in clinical outcome.
