  1. Univariate analysis of variables associated with mortality observed in patients with severe sepsis and septic shock in the ICU/HRTN between April 2011 and October 2012 (n = 72). MAP, mean arterial pressure; PCT, procalcitonin; PEEP, positive end expiratory pressure; PIP, peak inspiratory pressure; t, time (days).
