ASA Physical Status Calculator

ASA Physical Status Calculator for Trauma & Surgery. Class VI is a distinct organ-donor context, not simply a more severe living-patient class. The official definitions and examples are not reproduced here. Retain the assigned class, urgency and planned procedure together. Do not estimate a mortality percentage or anesthetic plan from this number.

How this calculator works

ASA class is assigned by an anesthesia professional using source criteria, not obtained by summing points. The emergency E designation is not an additional numeric point. Source: https://www.asahq.org/standards-and-practice-parameters/statement-on-asa-physical-status-classification-system

When to use this calculator

Use to preserve a class already recorded in an anesthesia assessment. Retain procedure and urgency alongside it rather than treating the class as a complete operative-risk model.

Inputs used

  • Previously assigned integer class, 1-6; emergency designation retained separately

Clinical interpretation

Class VI is a distinct organ-donor context, not simply a more severe living-patient class. The official definitions and examples are not reproduced here. Retain the assigned class, urgency and planned procedure together. Do not estimate a mortality percentage or anesthetic plan from this number.

Worked example

An assessment documented as III E remains class 3 plus an emergency designation. It must not be entered as 4 to represent urgency. A class 3 is not 3% operative mortality.

Limitations and safety notes

Class VI has a distinct organ-donor context and is not simply a worse living-patient category. Official ASA pages were inaccessible in this browsing run; the source identity and these limited facts were cross-checked through a permission-attributed society publication. No official definitions or examples are reproduced.

Frequently asked questions

Does this assign an ASA class for me?

No. It records the professional's assigned class and cannot replace preanesthetic assessment.
