Brief Summary:
A multi-center, prospective, single-visit study designed to acquire physiologic pulse oximeter waveform data during standard polysomnography (PSG) studies performed at multiple different Sleep Lab Centers.

Condition or disease
Sleep-Disordered Breathing Obstructive Sleep Apnea Sleep Apnea Central Sleep Apnea

Detailed Description:
The polysomnograms are clinically indicated studies in patients suspected of having sleep-disordered breathing, including, but not limited to: obstructive sleep apnea, complex sleep apnea and/or central sleep apnea. Subjects who have been prescribed with needing a polysomnography (PSG) will be enrolled into the study.

Polysomnography (PSG) Subjects
Subjects who have been prescribed with needing a polysomnography (PSG) will be enrolled into the study.

Primary Outcome Measures :
  1. Sensitivity and Specificity Data of the Saturation Pattern Detection (SPD) Feature as a Predictor of Repetitive Reductions in Airflow (RRiA). [ Time Frame: 9 Hours ]
    Sensitivity and specificity were computed from the count of instances in which the Saturation Pattern Detection (SPD) index value (vs. Polysomnography) within a discrete ten minute interval correctly identified a Repetitive Reduction in Airflow (RRiA) as being present within that interval (True Positive), absent (True Negative), or incorrectly identified presence or absence (False Positive and False Negative, respectively). Sensitivity is True Positive divided by True Positive plus False Negative TP/(TP+FN). Specificity is True Positive divided by True Negative plus False Positive TP/(TN+FP).
