Estimating Shock Success by Monitoring Changes in Spectral Data

摘要

This document presents a system for managing treatment for an emergency cardiac event. The system includes memory, one or more electronic ports for receiving ECG signals, and a treatment module executable on one or more processing devices. The module is configured to perform a number of transformation on portions of an ECG signal into frequency domain data, obtain one or more previous values derived from one or more time segments of the ECG, and determine, based on the frequency domain data a first value and a second value, determine a probability of therapeutic success. The module is further configured to cause one or more output devices to present an indication of the probability of therapeutic success.

主权项

1. A system comprising:
one or more electronic ports for receiving signals from sensors for obtaining a time domain electrocardiogram (ECG) of a patient; and a patient treatment module comprising an ECG analyzer and a non-transitory computer-readable storage medium encoded with a computer program comprising instructions that, when executed, cause one or more processors to perform operations comprising:
performing at least one transformation of at least a portion of a time domain ECG signal from the patient into frequency domain data,determining a first frequency-based value over a first evaluation period based on the at least one transformation,determining a second frequency-based value representing a trend over a second evaluation period based on the at least one transformation,determining a probability of therapeutic success based at least in part on the first frequency-based value and the second frequency-based value, andproviding an indication of the probability of therapeutic success.
