E. Scoring Respiratory Effort-Related Arousal

Scoring respiratory effort-related arousals is optional as noted in Parameters to be Reported II.F.

1. If electing to score respiratory effort-related arousals, score a respiratory event as a respiratory effort-related arousal (RERA) if there is a sequence of breaths lasting 10 seconds characterized by increasing respiratory effort or by flattening of the inspiratory portion of the nasal pressure (diagnostic study) or PAP device flow (titration study) waveform leading to arousal from sleep when the sequence of breaths does not meet criteria for an apnea or hypopnea. (see Figure 3)
