Table 2. Model Parameters for Responses in Blood Flow Velocity at the Middle Cerebral Artery in Study 1: N2O vs. Propofol/N2O Anesthesia
Values are shown as mean ± SD.
*Significance levels of differences between the two anesthetic conditions (row-wise comparison).
†P < 0.05, ‡P < 0.01, and §P < 0.001; column-wise comparison between the on and off responses (i.e. , τon vs. τoff and Gon vs. Goff) in either anesthetic condition.
Td, pure time delay; τon, time constants for the on responses; τoff, time constants for the off responses; FVMCA, blood flow velocity at the middle cerebral artery; Gon, gains for the on responses expressed as percent changes from the baseline FVMCA; Goff, gains for the off responses expressed as percent changes from the baseline FVMCA.
