Respiratory Event-Induced Blood Pressure Oscillations Vary by Sleep Stage in Sleep Apnea Patients

Figure 3

Aggregation of SBP apnea-elicited BP oscillations for a sample subject (34 SBP surges aggregated). The vertical dash line signifies the center of the aggregation window which is the point of alignment SBP of all the isolated apneas for the subject. The abbreviation CI refers to the confidence interval, and the small red circle designates the peak of the mean of the aggregated SBP values.
