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, systems, and devices for determining pulseless electrical activity (PEA) are described. The method may include determining by using a first sensor on a person, a heart rate of the person based on sensed electrical activity of the person. A pulse rate of the person may be determined using a second sensor, the pulse rate of the person being based on at least one sensed parameter other than the sensed electrical activity. The method may then include determining a correlation of the determined heart rate and the determined pulse rate and then generating an alert event based at least in part on the correlation being outside of a predetermined threshold.

Abstract: Methods, apparatuses and systems are described for determining respiration through impedance measurements using only two electrodes. A drive signal may be applied to a person, using only two electrodes. Using the same electrodes, the fluctuations in the voltage of the drive signal are determined. The voltage fluctuations in the drive signal are the result of impedance variations in the person's thoracic cavity due to respiration. Therefore, the voltage fluctuations may be used to determine a respiration rate of the person. In doing so, the voltage fluctuations may be digitized using a sampling rate that is much less than the frequency of the applied drive signal.

Abstract: Methods, apparatuses and systems are described for monitoring physiological parameters by using one or more sensors at a person. First and second physiological parameters of the person are monitored. A determination may be made, at the one or more sensors, that at least one of the first and second physiological parameters has crossed a threshold. An alert event may be generated at the one or more sensors, based on the crossed thresholds. The alert event may then be transmitted to a computing device that is separate from the one or more sensors.
