Pulse oximetry-based Cardio-Pulmonary Resuscitation (CPR) quality feedback systems and methods

摘要

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 the 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 on CPR quality during compression process. Also, compression interruption during CPR can be evaluated based on a pulse waveform generated from the measured signals.
