ASA Grade
Physical Status
For education. Check every result.
Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.
How it is calculated
ASA grade describes the patient, not the operation and not the anaesthetic risk directly - though it correlates with outcome. It is deliberately simple and subjective, and interobserver agreement is only moderate.
About
The anaesthetist's grading of overall physical status before an operation, from healthy to moribund.
