Fig. 2From: Ventilation during continuous compressions or at 30:2 compression-to-ventilation ratio results in similar arterial oxygen and carbon dioxide levels in an experimental model of prolonged cardiac arrestSchematic illustration of the EIT analysis work chart. A The raw dzGlo curve. B The reconstructed sections after filtering. C Visual slices created with the automated analysis scheme from filtered sections. D Visual explanation of the V/D index. BL: baseline; dzGlo: global impedance change; TID: tidal impedance change; CA: cardiac arrest; V/D: ventral per dorsalBack to article page
