  1. aDenotes acute requirement for mechanical ventilation primarily due to acute lung injury, pneumonia, influenza, aspiration, exacerbation of chronic obstructive airway disease, or other acute lung disorder. APACHE II, Acute Physiology and Chronic Health Evaluation II; APPT, activated partial thromboplastin time; SD, standard deviation.
