摘要:
A method and system for determining a respiratory rate of a user using an electrocardiogram (ECG) segment of the user are disclosed. The method comprises decomposing the ECG segment into a plurality of functions and evaluating the plurality of functions to choose one of the plurality of functions based on a respiratory band power. The method includes determining the respiratory rate using the one of the plurality of functions and a domain detection.
摘要:
An apparatus and method for non-invasive monitoring and detection of sudden changes in cardiovascular hemodynamics, in which a PPG signal is obtained from a patient, a time-frequency spectrum (TFS) is computed from the PPG signal, instantaneous modulations at a plurality of time points defining a curve of a prominent frequency of oscillation are extracted from the TFS, a peak power spectral density sequence is computed using the instantaneous modulations, and instantaneous peak values for following prominent frequency oscillations are monitored.
摘要:
An apparatus and method is provided that provide, in real-time, an accurate detection and warning of dangerous blood or fluid loss to warn of impending hypovolemia, by non-invasive monitoring and processing of photoplethysmography data.
摘要:
Methods and systems for quantitatively detecting the presence of artifacts in physiological measurement data and for determining usable data among those that have been designated to be corrupted with artifacts are presented.
