Fig. 3From: End-tidal carbon dioxide variation after a 100- and a 500-ml fluid challenge to assess fluid responsivenessEtCO2 variation in responder and non-responder. Variation of end-tidal carbon dioxide after 500 ml (ΔEtCO2-500 ml), responders (R) defined as patients who increased cardiac index more than 15 % after fluid expansion and non-responders (NR) defined as patients who increased cardiac index <15 % after fluid expansionBack to article page
