Calculate the Modified Aldrete Score for post-anesthesia recovery assessment. Determines PACU discharge readiness based on activity, breathing, circulation, consciousness, and SpO₂.
The Aldrete Score Calculator evaluates post-anesthesia recovery using five clinical parameters: motor activity, respiration, circulation, consciousness, and oxygen saturation. The modified version replaced skin color with pulse oximetry.
Each item is scored from 0 to 2 for a maximum total of 10. A higher score indicates better recovery, and many facilities use a threshold of 9 or 10 for discharge readiness.
The Aldrete score helps standardize recovery assessment in the PACU. It gives a simple, repeatable framework for documenting whether a patient is recovering as expected after anesthesia.
It should be used together with pain control, nausea, surgical, and institutional discharge checks rather than as the only criterion.
Aldrete Score = Activity (0-2) + Respiration (0-2) + Circulation (0-2) + Consciousness (0-2) + O₂ Saturation (0-2) Maximum Score: 10 Discharge Threshold: ≥ 9 (institutional protocols may vary) Each component scored 0 (worst) to 2 (best).
Result: 9 / 10 — Ready for Discharge
The patient moves all limbs (2), breathes deeply (2), has stable BP (2), is arousable on calling (1), and maintains SpO₂ >92% on room air (2). Total score = 9, meeting typical discharge criteria.
Dr. Jorge Antonio Aldrete, a Colombian-American anesthesiologist, published the original Post Anesthetic Recovery (PAR) score in 1970. Modeled after the Apgar score for newborns, it provided the first standardized method for assessing post-anesthesia recovery. The 1995 modification (replacing skin color with SpO₂) improved its clinical utility and objectivity.
The Aldrete score has been adopted worldwide as a standard component of PACU care. It is often integrated into electronic health record systems with automated scoring and alerting. Many accreditation bodies require documented post-anesthesia assessment using a validated tool like the Aldrete score.
While primarily designed for PACU use, the Aldrete score principles have been adapted for recovery monitoring after procedural sedation in endoscopy suites, radiology departments, emergency departments, and dental offices. Any setting where patients receive sedation or anesthesia can benefit from structured recovery assessment.

This calculator sums the five standard phase-I recovery items used in the modified Aldrete framework: activity, respiration, circulation, consciousness, and oxygen saturation. Each item is scored from 0 to 2, then combined into the usual 0-10 PACU recovery total shown on the page.
The result is a structured recovery-assessment aid, not a complete discharge checklist. Pain, nausea, surgical concerns, bleeding, and local discharge protocols still matter, so the score should be used as part of PACU recovery documentation rather than as the only discharge decision.
Many institutions use a threshold of 9 or 10 out of 10, but local protocols can differ.
It is commonly checked on PACU arrival and then at regular intervals until the patient meets discharge criteria.
The original score used skin color as the fifth criterion. The modified score uses pulse oximetry instead.
Yes. Pain, nausea, surgical requirements, and facility-specific discharge checks may still need to be met.
Yes. It is often used after procedural sedation or similar recovery assessments.
It can be used in children with appropriate clinical judgment, but some settings prefer pediatric-specific recovery tools.
