Total Number of Apneas and Hypopneas (Non-Supine): Apneas with >= 1% oxygen desaturation + hypopneas with > 50% flow reduction and >= 1% oxygen desaturation during artifact-free estimated sleep in non-supine position from type IV home sleep apnea test
slpa49 under Sleep Monitoring/Polysomnography/Respiratory Event Counts in HCHS variables
Apnea and hypopnea events were not distinguished as separate event types during scoring. Both were classified as a respiratory event that required a 50% reduction in Nasal Flow signal for at least 10 seconds.Estimated sleep duration, providing an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441) Any continuous periods of >=20 min with loss of respiratory channel was marked as wake and not included in the estimates.

Overall instability (NREM)
lgn under Sleep Monitoring/Polysomnography/Quantitative Respiratory Analysis in MESA variables
The magnitude of reflex (opposing) ventilatory drive response to a change in ventilation; it describes the ventilatory control stability and includes the effect of circulatory delays. Ventilatory drive is the level of ventilation that would be observed at any moment if the respiratory mechanics were normal, i.e. intended ventilation.
