PREdiction of Survival on ECMO Therapy-Score (PRESET-ECMO) Calculator If you are a human and are seeing this field, please leave it blank. Mean arterial pressure (mmHg) > 100 91–100 81–90 71–80 ≤ 70 Lactate concentration (mmol/L) ≤ 1.50 1.51–3.00 3.01–6.00 6.01–10.00 > 10.00 pH (arterial) > 7.300 7.201–7.300 7.101–7.200 ≤ 7.100 Platelet concentration (1,000/µl) > 200 101–200 ≤ 100 Hospital days pre ECMO ≤ 2 3–7 > 7 Total score (0-15) ICU Mortality = 26% ICU Mortality = 68% ICU Mortality = 93% Evidence Patients with a low (≤5) PRESET-Score showed a 74% survival rate in the derivation cohort and 86% in the internal validation cohort, respectively, assuming that these patients are good candidates for ECMO therapy when conventional therapy is unsuccessful. Here, the PRESET-Score might indeed serve as a good tool in decision-making, especially when resources are limited. If you are a human and are seeing this field, please leave it blank.
