  • PULSE OXIMETRY-BASED CARDIO-PULMONARY RESUSCITATION (CPR) QUALITY FEEDBACK SYSTEMS AND METHODS
    Publication number: 20180207058
    Abstract: Medical devices, plug-ins, systems, and methods for CPR quality feedback are disclosed. The medical devices can calculate peripheral circulation relevant parameters based on measured signals containing at least partial hemodynamic characteristics. Amplitude and area characteristics included in the peripheral circulation relevant parameters can further be determined for providing feedback and control relating to CPR quality during the compression process. Also, compression interruption during CPR can be evaluated based on a pulse waveform generated from the measured signals.
    Type: Application
    Filed: March 21, 2018

  • DEVICES AND SYSTEMS FOR REAL-TIME RECOGNITION OF RESTORATION OF SPONTANEOUS CIRCULATION (ROSC) IN CARDIO-PULMONARY RESUSCITATION (CPR) PROCESS
    Publication number: 20150164339
    Abstract: This disclosure relates to methods, devices and systems for real-time recognition of restoration of spontaneous circulation (ROSC) in the cardio-pulmonary resuscitation (CPR) process. Recognition mechanisms in both time domain and frequency domain are provided for the ROSC recognition, where the time-domain recognition logic may detect the ROSC by recognizing envelope features of sampled signals in the time domain, and the frequency-domain recognition logic may detect the ROSC by recognizing spectral peaks at different frequency points continuously or significant variations of amplitude of spectral peaks in the frequency spectrum.
