Microprocessor system for the analysis of physiologic and financial datasets
First Claim
1. ) A microprocessor system for evaluation of a patient, the system comprising:
- a monitor having a plurality of sensors for positioning adjacent said patient and a processor programmed to;
a) produce a first timed waveform based on a first physiologic parameter of a patient, b) produce a second timed waveform based on a second physiologic parameter which is generally subordinate to said first physiologic parameter, so that said second parameter normally changes in response to changes in said first parameter, c) identify pathophysiologic divergence of at least one of said first and second physiologic parameters in relationship to the other of said physiologic parameters, d) outputting an indication of said divergence.

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.

9. ) A method of monitoring a patient comprising:
-
a) monitoring a patient to produce a first timed waveform of a first physiologic parameter and a second timed waveform of a second physiologic parameter, the second physiologic parameter being physiologically subordinate to said first physiologic parameter, b) identifying a pattern indicative of divergence of at least one of said waveforms in relation to a physiologically expected pattern of the other of said waveforms, c) outputting an indication of said divergence. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
