Predicting risk of pulmonary complications for patients undergoing surgery under general, neuraxial, or regional anesthesia.

ARISCAT Score is calculated by adding up the selected points: Variable Criteria Points Age, years ≤50 0 51-80 3 >80 16 Preoperative SpO2 ≥96% 0 91-95% 8 ≤90% 24 Respiratory infection in the last month* No 0 Yes 17 Preoperative anemia (Hgb ≤10 g/dL) No 0 Yes 11 Surgical incision Peripheral 0 Upper abdominal 15 Intrathoracic 24 Duration of surgery <2 hrs 0 2-3 hrs 16 >3 hrs 23 Emergency procedure No 0 Yes 8 The scores can be interpreted as: ARISCAT Score Risk group Risk of in-hospital postoperative pulmonary complications* <26 Low 1.6% 26–44 Intermediate 13.3% ≥45 High 42.1% *Complications were defined as a composite including respiratory failure, respiratory infection, pleural effusion, atelectasis on chest x-ray, pneumothorax, bronchospasm treated with bronchodilators, and aspiration pneumonitis.
