Professional surgical risk assessment tool predicting postoperative pulmonary complications with ASA classification
Our ARISCAT + ASA calculator combines validated risk assessment tools for comprehensive preoperative evaluation.
Calculate the validated ARISCAT score (0-123) using 7 clinical parameters to predict postoperative pulmonary complication risk.
Standard ASA physical status classification (I-IV) assessment for overall patient health evaluation before anesthesia.
Categorize patients into Low (≤25), Intermediate (26-44), or High (≥45) risk groups with corresponding complication percentages.
Evidence-based clinical recommendations and preventive measures tailored to individual risk scores.
Detailed breakdown of individual risk factors contributing to the total ARISCAT score for targeted intervention.
Specific preventive measures including respiratory therapy, anesthesia techniques, and postoperative care plans.
Gather all necessary preoperative information: age, SpO₂, infection history, anemia status, surgical details, and ASA classification.
Input accurate values for all 7 ARISCAT parameters. Pay special attention to SpO₂ measurements and recent infection history.
Choose the appropriate ASA physical status class (I-IV) based on the patient's overall health condition and comorbidities.
Review the ARISCAT score, risk category, percentage risk, and implement recommended preventive measures.
