To describe and quantify early rehabilitation, we registered the time (in minutes) used on each of the early rehabilitation categories daily for each patient. The PT also registered when the mobilization step was changed. Factors of feasibility were as follows: the number of days until the initiation of early rehabilitation, the percent of patients not available for early rehabilitation and the percent of patients who could advance through our mobilization algorithm. We also registered the occurrence of vasospasm and the frequency of unintended removal of lines and tubes.
