Does this calculator replace the anesthetist?

No. It is only a mathematical aid. The anesthetic protocol must be defined by the veterinarian based on physical exam and diagnostics.

What is ASA classification?

It is a physical-status classification system: ASA I (healthy) to ASA V (moribund), regardless of the procedure.
