Signal Processing Method and Apparatus for Processing a Physiologic Signal such as a Photoplethysmography Signal
First Claim
1. A signal processing method of processing a physiologic signal having at least some cardiac components in the physiologic signal, the processing including the steps of:
- Identifying a potential cardiac component of a physiologic signal wherein the potential cardiac component has a series of peaks and valleys;
Calculating a comparison of the durations of a peak to valley sub-component and a valley to peak sub component of the potential cardiac component; and
Utilizing the calculated comparison to evaluate the potential cardiac component.

Abstract
A signal processing method of processing a physiologic signal, such as a Photoplethysmography Signal having at least some cardiac components and/or respirator components in the physiologic signal, the processing including the steps of: Identifying a potential cardiac and or respiratory components of a physiologic signal wherein the potential cardiac and or respiratory components have a series of peaks and valleys; Calculating a comparison of the durations of a peak to valley sub-component and a valley to peak sub component of the potential cardiac and or respiratory components; and Utilizing the calculated comparison to evaluate the potential cardiac and or respiratory components.
