Example Embodiment
[0027] Such as figure 1 As shown, an implementation of the pulse wave processing method of the present application includes the following steps:
[0028] Step 102: Process the measured signal, and the measured signal reflects the real-time pulse characteristics of the measured person. Which processes the measured signal, including:
[0029] Identify fluctuating components and constant components from the measured signal;
[0030] Generate pulse waves based on fluctuation components.
[0031] This application can establish a sliding time window, and display the pulse wave in the sliding time window.
[0032] Step 104: Perform pulse wave recognition according to the processing result.
[0033] In the state where the patient has not recovered the spontaneous circulation, high-quality chest compressions should be performed and interruptions should be minimized. Factors such as tracheal intubation or changing the press during manual compression often cause interruption of compression. The ...
Example Embodiment
[0079] Embodiment two:
[0080] Such as image 3 As shown, an implementation of the pulse wave processing device of the present application includes: an analog-to-digital conversion unit for processing the measured signal, and the measured signal reflects the real-time pulse characteristics of the subject; a digital signal processing unit, It is used to identify the pulse wave according to the processing result, and count the period of pulse wave disappearance according to the identification result; the output unit is used to output statistical information.
[0081] The analog-to-digital conversion unit is also used to identify the fluctuation component and the constant component from the measured signal, and the digital signal processing unit is also used to identify the pulse wave based on the fluctuation component.
[0082] In one embodiment, the digital signal processing unit is also used to count the duration of the pulse wave disappearance time.
[0083] In another embodiment, ...
