Surgical Risk & Assessment Calculators
Surgical tools — Revised Trauma Score, ASA Physical Status Classification, Parkland Formula, and NYHA Classification.
This category currently includes 4 tools, including ASA Class, RCRI Score, and Mallampati Score.
These resources are built for clinicians, trainees, and medically informed patients who need fast bedside calculations. Use the results as decision support and pair them with full clinical context and local guidelines.
All Surgery Tools (4)
ASA Class
Classify preoperative physical status using the ASA I–VI system for anesthetic risk stratification. ASA III+ indicates significant systemic disease requiring special perioperative planning and precautions.
RCRI Score
Estimate perioperative major cardiac event risk for non-cardiac surgery using the 6-factor Lee RCRI model.
Mallampati Score
Classify airway visibility (Class I-IV) to support difficult-airway risk assessment before anesthesia or airway procedures.
Caprini Score
Estimate postoperative venous thromboembolism risk using the Caprini point-based model for surgical patients.
