US Patent 9468378 Airway instability detection system and method

A system and method for data processing is disclosed. One example of a processor-based method comprises accessing data representative of a time series of at least one component of a timed waveform corresponding to a pulse, and searching the data for an occurrence of a cluster of variations induced by at least one of an apnea cluster and a hypopnea cluster. An exemplary system comprises a memory device adapted to access data representative of a time series of at least one component of a timed waveform corresponding to a pulse, and a processor adapted to search the data for an occurrence of a cluster of variations induced by at least one of an apnea cluster and a hypopnea cluster.
