Patient signal analysis based on actiniform segmentation

摘要

Disclosed herein is a framework for facilitating patient signal analysis. In accordance with one aspect, actiniform segmentation is performed on patient signal data waveform based on an actiniform shape. The actiniform shape is centered at a peak of the waveform and includes connection lines extending from the peak to key time points of the patient signal data waveform. Actiniform parameters may be extracted from the segmented patient signal data waveform. Additionally, one or more actiniform ratios may be determined based on the actiniform parameters to monitor changes in the patient signal data waveform.

主权项

1. A system for patient signal analysis, comprising:
a patient monitor configured to acquire a patient signal data waveform from a patient; a medical treatment device configured to provide treatment to the patient; and a computer system communicatively coupled to the patient monitor and the medical treatment device, wherein the computer system includes a non-transitory memory device for storing computer readable program code, and a processor in communication with the memory device, the processor being operative with the computer readable program code to perform steps including performing actiniform segmentation on the patient signal data waveform based on an actiniform shape centered at a peak of the waveform, extracting actiniform parameters from the segmented patient signal data waveform, determining one or more actiniform ratios based on the actiniform parameters, determining control parameters based on the one or more actiniform ratios, and controlling the medical treatment device by applying the control parameters.
