Figure 3From: Extracorporeal life support following out-of-hospital refractory cardiac arrestDistribution of the values of no flow (top), low flow (middle) and end tidal CO 2 (E T CO 2 ) (bottom) initial arterial pH, blood lactate and kalemia in the studied population ( n = 51). The gray zones and vertical bars indicate the threshold considered in the French guidelines for no flow (≤5 min), low flow (≤100 min) and ETCO2 (≥10 mmHg).Back to article page
