Title: SYSTEM AND METHOD FOR CHARACTERIZING RESPIRATORY STRESS
Abstract:
A system and method for evaluating the respiratory health of a patient and indicating and characterizing respiratory stress includes a sensor in operative communication with a patient for generating at least one biological signal, having a waveform curve in the time domain. The biological signal is processed and a waveform curve is computed, reflective of the respiration rate of the patient. A correlation is then determined between the biological signal waveform curve and respiration rate waveform curve and a respective correlation coefficient is determined. Frequency analysis is performed on the biological signal and a determination is made of a respiration metric reflective of the ratio of spectral components associated with the respiration component of the biological signal in relation to the total spectral components for the biological signal. The correlation coefficient and the respiration metric are combined to form a respiratory stress metric for displaying to a user.
