Statistical Analysis
low mean arterial pressure
Randomized patients were considered to have received the intervention and were included in the intention-to-treat analysis regardless of whether the ACT communicated with the OR. Continuous outcomes (time with low mean arterial pressure, time without antibiotics, and fresh gas flow) were analyzed using a linear generalized estimating equation model clustering on OR and day. Standard errors were calculated using the heteroskedasticity-consistent (HC) type 1 (HC1) estimator from sandwich package 3.0-0 in R software, version 4.0.4 (R Foundation for Statistical Computing).
