Results

The present study is a follow-up on our earlier research series, and is based on reanalysis of the data obtained from the previous research series.
Participants were given the opportunity to decline consent using an opt-out method; none of the participants requested withdrawal from the study.
To estimate ICP during sedation, we analyzed the data from 42 healthy male volunteers whose waveforms were available for calculation of nICP in the previous research series.
