Lung Injury Prediction Score calculation worksheet (with permission from the American Thoracic Society) [24].

	LIPS points	Examples
Predisposing conditions		(1) Patient with history of alcohol abuse with septic shock from pneumonia requiring FIO2 > 0.35; Emergency room: sepsis + shock + pneumonia + alcohol abuse + FIO2 > 0.35; 1 + 2 + 1.5 + 1 + 2 = 7.5; (2) Motor vehicle accident with traumatic brain injury, lung contusion, and shock requiring FIO2 > 0.35; Traumatic brain injury + lung contusion + shock + FIO2 > 0.35; 2 + 1.5 + 2 + 2 = 7.5; (3) Patient with history of diabetes mellitus and urosepsis with shock sepsis + shock + diabetes; 1 + 2 − 1 = 2
Shock	2
Aspiration	2
Sepsis	1
Pneumonia	1.5
High-risk surgery
Orthopedic spine	1
Acute abdomen	2
Cardiac	2.5
Aortic vascular	3.5
High-risk trauma
Traumatic brain injury	2
Smoke inhalation	2
Near drowning	2
Lung contusion	1.5
Multiple fractures	1.5
Risk modifiers
Alcohol abuse	1
Obesity (BMI > 30)	1
Hypoalbuminemia	1
Chemotherapy	1
FIO2 > 0.35 (>4 L/min)	2
Tachypnea (RR > 30)	1.5
SpO2 < 95%	1
Acidosis (pH < 7.35)	1.5
Diabetes mellitus	−1

BMI = body mass index; RR = respiratory rate; SpO₂ = oxygen saturation by pulse oximetry.
Add 1.5 points in case of emergency surgery.
Only in cases of sepsis.
