Microprocessor system for the analysis of physiologic and financial datasets
First Claim
1. A method for titration of airway pressure in the treatment of sleep disordered breathing, comprising:
- a processor searching a plurality of multi-signal objects, wherein the plurality of multi-signal objects includes data from at least two signals, wherein the at least two signals includes signals from at least one of oximetry, chest wall movement, or EEG data, the multi-signal objects indicating a pattern of a plurality of apneas, a pattern of a plurality of hypopneas, or a pattern of a combination of at least one apnea and at least one hypopnea; and
an auto-titration continuous positive airway pressure system titrating a pressure to a nasal passage of a patient if the pattern of the plurality of apneas, the pattern of the plurality of hypopneas, or the pattern of the combination of at least one apnea and at least one hypopnea is detected.

Abstract
A system and method for organization and analysis of complex and dynamically interactive time series is disclosed. One example comprises a processor based system for relational analysis of physiologic signals for providing early recognition of catastrophic and pathologic events such as pathophysiologic divergence. The processor is programmed to identify pathophysiologic divergence of at least one of first and second physiologic parameters in relationship to the other and to output an indication of the divergence. An object-based method of iterative relational processing waveform fragments in the time domain is described wherein each more complex waveform object inherits the characteristics of the waveform objects from which it is derived. The first physiologic parameter can be the amplitude and frequency of the variation in chest wall impedance or nasal pressure and the second parameter can be a measure or indication of the arterial oxygen saturation.
