Overview

VF analysis during CPR lacks reliability for guiding shocks; leaves open whether artifact-robust algorithms can achieve predictive accuracy.

Structured PICO

Do algorithms analyzing ventricular fibrillation signals accurately predict the success of defibrillation during CPR?

P
Population
Subjects (humans and animals) with ventricular fibrillation undergoing CPR and defibrillation
I
Intervention
Algorithms to analyze ventricular fibrillation signals (including amplitude, frequency, bispectral analysis, amplitude spectrum area, wavelets, nonlinear dynamics, N(alpha) histograms)
O
Outcome
Prediction of the success of defibrillation

Current algorithms for analyzing ventricular fibrillation signals lack adequate predictive power for successful defibrillation and struggle to cope with CPR artifacts.

Limitations

  • Small number of subjects, which precludes separation into training and test data
  • Many investigations are animal studies of untreated short ventricular fibrillation, which may differ from prolonged ventricular fibrillation in humans
