Abstract
Techniques for detecting sleep events are disclosed. In some embodiments, a continuous non-invasive blood pressure (“CNIBP”) monitoring system may be used to obtain blood pressure values from a subject during a sleep study. Changes in the blood pressure over time may be determined and analyzed in order to identify a sleep event. The localized blood pressure changes may be interpreted in isolation or in combination with other signals collected from the subject.
