Of the 100 patients interviewed, 99 were keen to help,
though five of them had no recollection at all of the Unit.
The remaining patient declined to continue answering half
way through the interview. There were 65 males and 35
females. Twenty two required artifical ventilation. The
other monitoring and support "lines" are shown in Table
1. The duration of stay in the Unit of these 100 patients
ranged from seven hours to five days, with a mean of
39.6 h. Only five patients stayed for more than four days.
