WebConclusion There is only moderate correlation of ETCO2 and PaCO2 at hospital arrival in patients with serious TBI. The mean ETCO2–PaCO2 gradient was 1.7 (±1.0) kPa (12.8 mm Hg). Lower ETCO2 targets than previously recommended may be safe and appropriate, and there may be a role for prehospital PaCO2 measurement. ... WebThe correlation coefficients between ETCO2and PaCO2were 0.95 (mean gradient = 0.3 ± 2.1) for Vd/Vt ≤ 0.4, 0.88 (mean gradient = 5.9 ± 4.3) for Vd/Vt 0.41-0.55, 0.86 (mean …
