Claim Text:
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.
