This disclosure relates to methods, devices and systems for real-time recognition of restoration of spontaneous circulation (ROSC) in 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.

Devices and systems for real-time recognition of restoration of spontaneous circulation (ROSC) in cardio-pulmonary resuscitation (CPR) process

An information transmission method is provided, including: A control device obtains a second universal serial bus video class UVC port and a second virtual network port based on configuration of a universal serial bus USB port of the control device. The control device determines address information of a camera device, where a first UVC port and a first virtual network port are configured on the camera device, and the first UVC port and the first virtual network port are obtained based on configuration of a USB port of the camera device. The control device sends the address information to the camera device through a UVC channel, where the UVC channel is established based on the first UVC port and the second UVC port.

Information transmission method and related device

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.
