  1. aAdd 1.5 points if emergency surgery. bOnly if sepsis. Example 1: patient with a history of alcohol abuse with septic shock from pneumonia requiring FiO2 >0.35 in the emergency room; sepsis (1) + shock (2) + pneumonia (1.5) + alcohol abuse (1) + FiO2 >0.35 (2) = 7.5. Example 2: motor vehicle accident with traumatic brain injury, lung contusion, and shock requiring FiO2 >0.35; traumatic brain injury (2) + lung contusion (1.5) + shock (2) + FiO2 >0.35 (2) = 7.5. Example 3: patient with a history of diabetes mellitus and urosepsis with shock; sepsis (1) + shock (2) + diabetes (-1) = 2. BMI, body mass index; FiO2, fraction of inspired oxygen; LIPS, Lung Injury Prediction Score; RR, respiratory rate; SpO2, oxygen saturation by pulse oximetry.
