Tight control of CO2 (Paco2), a potent regulator of cerebrovascular tone, is generally advocated, but its vasomotor effect may be short-lived.

Clinical outcomes included 90-day mortality and ventilator-free days (VFD) until day 28. Exploratory analyses included an evaluation of plasma indices of lung injury, inflammation, and heterogeneity of treatment effect (HTE). Seventy-nine patients were enrolled, and 69 patients had paired plasma samples taken at baseline and day 3. There was no difference in day 3 plasma CRP (intervention 138.6 [70.4, 189.4] vs. standard care 113.0 [62.7, 233.8] mg/L; p = 0.72). Between baseline and day 3, there was a greater increase in plasma interleukin-18 in patients that received intervention compared with those that received standard care (Δ 337.7 [-128.9, 738.9] vs. 6.4 [-457.2, 6.4] pg/mL p = 0.05). In patients with high interleukin-18, allocation to intervention was associated with increased VFDs (p = 0.03).
