Efficiency of on-site ECMO treatment: a Effect of ECMO on oxygenation. ECMO significantly increased Horowitz Index with 30 min post implantation. Mean Horowitz Index pre-cannulation 99.2 ± 60.6, IQR 64–114, post-cannulation 202.8 ± 133.6, IQR 95.5–273.3, p < 0.0001, b pH was significantly improved from mean 7.2 ± 0.1, IQR 7.1–7.3 pre ECMO to 7.3 ± 0.14, IQR 7.2–7.4, p < 0.0001. c Arterial blood gas analysis prior and following ECMO initiation: PaO2 was significantly increased from mean 86.2 ± 47.4 mmHg, IQR 61.8–93, to 206.6 ± 135.3 mmHg, IQR 94–275, p < 0.0001. PaCO2 was significantly lowered by ECMO from mean 70.2 ± 24.4 mmHg, IQR 52–83.5, to 47.98 ± 17.4 mmHg, IQR 37–53.3. d Lactate levels were not significantly improved by ECMO treatment. Mean arterial lactate pre ECMO initiation was 4.08 ± 5 mmol/l, IQR 1.01–5.87, and post implantation 3.9 ± 4.2 mmol/l, IQR 1.3–4.9
