    Abstract: A method for determining an efficacy of cardiopulmonary resuscitation (CPR) includes receiving a plethysmography signal from an oximetry sensor and an electrocardiogram (ECG) signal from an ECG sensor at a processor associated with a patient monitor, the oximetry sensor, or the ECG sensor. The method includes determining a first indicator related to the efficacy of CPR based on the plethysmography signal, using the processor. The method also includes determining a second indicator related to the efficacy of CPR based on the ECG signal, using the processor. The method further includes combining the first indicator and the second indicator to determine a combination metric indicative of the efficacy of CPR, using the processor.

    Abstract: The present invention relates to physiological signal processing, and in particular to methods and systems for processing physiological signals to predict a fluid responsiveness of a patient. A medical monitor for monitoring a patient includes an input receiving a photoplethysmograph (PPG) signal representing light absorption by a patient's tissue. The monitor also includes a perfusion status indicator indicating a perfusion status of the PPG signal, and a fluid responsiveness predictor (FRP) calculator programmed to calculate an FRP value based on a respiratory variation of the PPG signal. The FRP calculator applies a correction factor based on the perfusion status indicator.

    Abstract: Methods, systems, and devices for measuring respiratory parameters from an ECG device are described. The method may include receiving an electrocardiogram (ECG) signal associated with a patient. The method may further include detecting a change in modulation of the ECG signal between a first portion of the ECG signal and a second portion of the ECG signal. The method may further include determining a change in respiratory effort of the patient based at least in part on the change in modulation.

    Abstract: Methods and systems are provided for determining fluid administration. The system may determine fluid administration based on the fluid responsiveness and regional oxygen saturation of a subject. The system may receive the fluid responsiveness and regional oxygen saturation from external sources or may determine one or both based on received physiological signals. In some embodiments, the system may determine whether to administer fluid based on the fluid responsiveness and regional oxygen saturation. In some embodiments, the system may determine the amount of fluid to administer based on the fluid responsiveness and regional oxygen saturation. In some embodiments, the system may determine the effectiveness of fluid administration. In some embodiments, the system may provide an indication of the determined fluid administration so that a care-giver can implement the appropriate fluid administration. In some embodiments, the system may control the fluid administration based on its determination.

    Abstract: A system may include a photoplethysmograph (PPG) sensor configured to be secured to a patient and to generate a PPG signal for the patient. The system may also include a motion sensor configured to generate a motion signal indicative of motion of the patient. Further, the system may include a controller configured to receive the PPG signal from the PPG sensor and the motion signal from the motion sensor, to analyze the motion signal to detect motion of the patient, and to deactivate the at least one emitter of the PPG sensor based on the analysis of the motion signal when motion of the patient is detected.

    Abstract: Methods and systems are presented for determining physiological information in a physiological monitor. A physiological signal (e.g., an EEG signal) received from a subject is wavelet transformed and first and second related features that vary in scale over time are identified in the transformed signal. First and second coupled ridges of the respective first and second related features may also be identified in the transformed signal. A non-stationary relationship parameter is determined and is indicative of the relationship between the first and second features and/or between the first and second ridges. Physiological information, which may be indicative of a level of awareness of a subject, is determined based on the non-stationary relationship parameter. This physiological information may be used, for example, in an operating room to monitor/regulate the subject's anesthetic state while under general anesthesia or in an intensive care unit to monitor the subject's sedateness and administer medication accordingly.
