Variation and correlation of end –tidal CO2 and amplitude spectrum area in a refractory ventricular fibrillation. A case from the ReCaPTa study

A refractory Ventricular Fibrillation (VF) is a challenge for the emergency teams. Hemodynamic monitoring during cardiopulmonary resuscitation (CPR) helps to maintain high quality. A retrospective study reported recently that the higher the end-tidal carbon dioxide (ETCO2) was prior to the shock, the higher the chance of success [1]. In another study the Amplitude Spectrum Area (AMSA) of 17 mV-Hz predicted defibrillation success in two thirds of cases [2]. The correlation between ETCO2 and AMSA and its variation has never been described in a long case of refractory VF.
