Abstract
Method and device for continual physiological monitoring in which the display of physiological parameter estimates is conditioned on conformance of the estimates with expectations. Current estimates of physiological parameters are compared with expectations for the current estimates determined using prior estimates of the physiological parameters. Nonconformance with expectations can result in display of information indicating present unavailability of an estimate for the physiological parameter. The method and device are adaptable for use with various types of monitored physiological parameters and various expectation metrics.
Claims20
A method for continual physiological monitoring, comprising:
- acquiring by a physiological monitoring device a physiological signal;
- calculating by the device a current estimate of a physiological parameter from the physiological signal;
- evaluating by the device conformance of the current estimate with expectations for the current estimate determined by the device using one or more prior estimates of the physiological parameter calculated by the device from the physiological signal;
- and
- displaying by the device information regarding the current estimate determined by the device based at least in part on the evaluation.
A physiological monitoring device, comprising:
- a physiological data capture system;
- a physiological data acquisition system communicatively coupled with the capture system;
- a physiological data processing system communicatively coupled with the acquisition system;
- and
- a physiological data output interface communicatively coupled with the processing system, wherein the processing system receives a physiological signal from the capture system via the acquisition system, calculates a current estimate of a physiological parameter from the physiological signal, evaluates conformance of the current estimate with expectations for the current estimate determined using one or more prior estimates of the physiological parameter calculated from the physiological signal, and transmits to the output interface information regarding display of the current estimate determined based at least in part on the evaluation, whereupon information regarding the current estimate is displayed on the output interface.
