1. A method for heart function analysis, comprising:
- receiving, by a processor, patient signal data from a patient, the patient signal data including SPO2 signal data received from an oximeter and indicative of saturation of hemoglobin with oxygen and respiration signal data received from a respiratory monitor;
using a signal data analysis unit to synchronize the SPO2 signal data by gating the SPO2 signal using the respiration signal to select a first cycle of the SPO2 signal which corresponds to exhalation of the patient and a second cycle of the SPO2 signal which corresponds to inspiration of the patient;
determining, by the processor, one or more waveform parameters based on the selected cycles of the synchronized SPO2 signal data;
determining, by the processor, one or more respiration-SPO2 parameters based on the one or more waveform parameters;
determining a heart function based on the one or more respiration-SPO2 parameters; and
generating a patient report indicating the determined heart function.

Abstract
Disclosed herein is a framework for facilitating biological tissue function analysis. In accordance with one aspect, saturation of hemoglobin with oxygen (SPO2) signal data is synchronized with respiration signal data. One or more waveform parameters may be generated based on the synchronized SPO2 signal data and the respiration signal data. One or more respiration-SPO2 parameters may then be determined based on the one or more waveform parameters and used to characterize the biological tissue function.
