Aldrete Score Calculator
The Aldrete Score Calculator adds up the five post-anesthesia recovery criteria — activity, respiration, circulation, consciousness and oxygenation — each scored 0 to 2, to assess whether a patient is ready for discharge from the recovery room. A total of 9 or more usually indicates readiness.
Rates and fees change frequently. Always confirm the current figures
with the official authority before relying on this result.
Formula
Score = Activity + Respiration + Circulation + Consciousness + Oxygenation
- Each of the five criteria — activity (movement), respiration, circulation (blood pressure), consciousness and oxygenation — is scored 0, 1 or 2.
- The five scores are summed for a total out of 10.
- A score of 9 or more generally indicates the patient has recovered enough to leave the post-anesthesia care unit.
- This is a clinical aid; discharge decisions must be made by qualified anesthesia or recovery staff.
Example Calculation
Inputs
- Activity (0-2): 2
- Respiration (0-2): 2
- Circulation (0-2): 2
- Consciousness (0-2): 2
- Oxygenation (0-2): 2
A fully recovered patient scoring 2 in every category totals 2+2+2+2+2 = 10, comfortably above the threshold of 9 for discharge readiness.
Frequently asked questions
What is the Aldrete score?
It is a post-anesthesia recovery score that rates activity, respiration, circulation, consciousness and oxygenation from 0 to 2 each to judge readiness to leave recovery.
What score is needed for discharge?
A total of 9 or 10 out of 10 is typically required before a patient can be discharged from the recovery room.
What do the five criteria mean?
They assess voluntary movement, breathing ability, blood pressure stability, level of consciousness and oxygen saturation after anesthesia.
Is there a modified version?
Yes. The modified Aldrete score replaces colour with oxygen saturation, which is the version used here.
Does this replace clinical judgment?
No. It supports recovery monitoring but discharge must be confirmed by trained clinical staff.
