Of the 22 patients who were ventilated artificially, only
seven had any recollection of the experience. Of these,
one made a fair estimate (< 50% error) and the other six
inaccurate estimates of the duration of ventilation. Fifteen
patients were ventilated for 12 h or less, six more for
12 - 14 h and one for 48 h. The mean period of ventilation
was 14.59 h.
