The Aldrete Score, also known as the Post-Anesthesia Recovery Score (PARS), is a system used by healthcare professionals to assess the recovery of patients coming out of anesthesia. It’s like the ultimate report card for your post-surgery snooze fest. Originally developed by Dr. Jorge Aldrete in 1970, the Aldrete Score helps determine when a patient is ready to leave the post-anesthesia care unit (PACU) and get on with their life—or at least move to the next stage of recovery.
The score evaluates five key criteria: activity, respiration, circulation, consciousness, and oxygen saturation. Each of these criteria is scored on a scale of 0 to 2, with a maximum total score of 10. A higher score means the patient is recovering well, while a lower score might indicate the need for more care and monitoring.
In this guide, we’re going to dive deep into each of these criteria, explore common mistakes and tips for accurate scoring, answer some burning questions, and walk through the scoring process step by step. Ready to become an Aldrete Score expert? Let’s go!

Understanding the Five Key Criteria
Activity
The first criterion in the Aldrete Score is activity. This measures the patient’s ability to move voluntarily or on command. Here’s how the scoring breaks down:
- 2 points: The patient can move all four extremities on command.
- 1 point: The patient can move two extremities on command.
- 0 points: The patient is unable to move any extremities or moves spontaneously.
Respiration
Next up is respiration. This criterion assesses how well the patient is breathing post-anesthesia:
- 2 points: The patient is breathing deeply and coughing freely—like they just woke up from a great nap.
- 1 point: The patient has dyspnea (difficulty breathing) or shallow, irregular breaths.
- 0 points: The patient is apneic (not breathing) or requires ventilatory support.
Circulation
The circulation criterion checks the patient’s blood pressure compared to their pre-anesthesia baseline:
- 2 points: Blood pressure is within 20% of the baseline.
- 1 point: Blood pressure is within 20-50% of the baseline.
- 0 points: Blood pressure is more than 50% above or below the baseline.
Consciousness
Consciousness evaluates how awake and aware the patient is:
- 2 points: The patient is fully awake and alert.
- 1 point: The patient is arousable on calling (needs a little nudge).
- 0 points: The patient is not responsive.
Oxygen Saturation
Finally, we have oxygen saturation—a measure of how well the blood is carrying oxygen:
- 2 points: Oxygen saturation is 92% or higher on room air.
- 1 point: Oxygen saturation is less than 92% while the patient is on supplemental oxygen.
- 0 points: Oxygen saturation is less than 90% even with supplemental oxygen.
Common Mistakes vs. Tips
| Common Mistakes | Tips |
|---|---|
| Overestimating patient activity: Assuming a patient who can move two extremities can move all four. | Verify movement: Always ask the patient to move each extremity. It’s okay to double-check! |
| Ignoring pre-anesthesia vitals: Failing to compare post-anesthesia blood pressure to baseline. | Baseline comparison: Always have the pre-anesthesia baseline handy for accurate comparison. |
| Misinterpreting consciousness: Assuming a groggy patient is fully awake. | Give them a moment: Wait until the patient is fully responsive before scoring. |
| Neglecting supplemental oxygen: Forgetting to account for supplemental oxygen when measuring oxygen saturation. | Check the O2 source: Always note if the patient is on room air or supplemental oxygen. |
| Rushing the assessment: Trying to score the patient too quickly, leading to inaccuracies. | Take your time: A thorough assessment is key to an accurate score. |
Step-by-Step Guide to Using the Aldrete Score
Pre-Assessment
✅ Review the patient’s baseline vitals: Ensure you know the pre-anesthesia blood pressure and oxygen saturation levels.
✅ Prepare necessary equipment: Have a stethoscope, blood pressure cuff, and pulse oximeter at the ready.
Assessment
✅ Assess Activity: Ask the patient to move their arms and legs. Score based on the number of extremities they can move.
✅ Evaluate Respiration: Listen to the patient’s breathing. Check if they are breathing deeply, shallowly, or if they need ventilatory support.
✅ Check Circulation: Measure the patient’s blood pressure and compare it to their baseline.
✅ Assess Consciousness: Determine how alert the patient is. Are they fully awake, or do they need some prompting?
✅ Measure Oxygen Saturation: Use the pulse oximeter to check the patient’s oxygen levels, noting whether they’re on room air or supplemental oxygen.
Post-Assessment
✅ Calculate the total score: Add up the points from each criterion.
✅ Interpret the score: A score of 9-10 usually indicates the patient is ready to leave the PACU. A lower score may require further monitoring or intervention.
✅ Document the score: Record the Aldrete Score in the patient’s chart along with the time of assessment and any relevant observations.
Frequently Asked Questions (FAQs)
What is the purpose of the Aldrete Score?
The Aldrete Score is used to assess a patient’s recovery from anesthesia, determining when they’re ready to be moved from the PACU to a less intensive care setting or discharged.
How often should the Aldrete Score be assessed?
The Aldrete Score is typically assessed upon arrival in the PACU and then at regular intervals, such as every 15 minutes, until the patient meets discharge criteria.
Can the Aldrete Score be used for all patients?
While it’s a widely used tool, the Aldrete Score may need to be adapted for certain populations, such as pediatric or geriatric patients, or those with pre-existing conditions that affect consciousness, respiration, or circulation.
What happens if a patient has a low Aldrete Score?
A low Aldrete Score indicates that the patient may not be ready to leave the PACU. They might need additional monitoring, oxygen therapy, or other interventions.
Is the Aldrete Score the only tool used to assess post-anesthesia recovery?
No, the Aldrete Score is one of several tools used in post-anesthesia care. Others may include pain assessment scales, fluid balance monitoring, and neurological assessments.
Wrapping It Up
The Aldrete Score is a crucial tool for ensuring patients safely transition out of anesthesia. By evaluating activity, respiration, circulation, consciousness, and oxygen saturation, healthcare professionals can make informed decisions about a patient’s readiness to leave the PACU. Whether you’re a seasoned pro or new to post-anesthesia care, understanding the Aldrete Score can make a world of difference in patient outcomes.
And remember, while it’s important to follow the scoring system closely, don’t forget to apply clinical judgment. No score is a substitute for the insight and expertise you bring to patient care.
