Obesity-induced chronic inflammation status is well documented to contribute to the progress of multiple diseases 18 . Large epidemiological studies have shown that BMI was associated with increased risk of acute respiratory distress syndrome (ARDS) and length of hospital stay, which has already been used in lung injury prediction score (LIPS) to help physicians identify at-risk patients for developing ALI 19 .
