Assess readiness for PACU discharge with the modified Aldrete score.
Clinical takeaway
Score ≥ 9 with no single 0 is a typical discharge threshold.

When to use
Post-anaesthesia recovery discharge decisions.
How it works
0–2 points each for activity, respiration, circulation, consciousness and oxygen saturation (max 10). ≥ 9 commonly indicates readiness.
Key points
- Score ≥ 9 with no single 0 is a typical discharge threshold.
- Also confirm pain, nausea and surgical-site status.
- Follow local PACU discharge policy.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Activity (moves extremities) | All four on command (2) |
|---|---|
| Respiration | Breathes deeply, coughs freely (2) |
| Circulation (BP vs baseline) | ± 20 mmHg (2) |
| Consciousness | Fully awake (2) |
| Oxygen saturation | SpO₂ > 92% on air (2) |
→Aldrete10/10
- Interpretation：Generally ready for discharge from PACU
| Activity (moves extremities) | None (0) |
|---|---|
| Respiration | Apnoeic (0) |
| Circulation (BP vs baseline) | ± > 50 mmHg (0) |
| Consciousness | Not responding (0) |
| Oxygen saturation | < 90% with O₂ (0) |
→Aldrete0/10
- Interpretation：Not yet ready — continue recovery monitoring

- Inputs: Activity (moves extremities) All four on command (2), Respiration Breathes deeply, coughs freely (2), Circulation (BP vs baseline) ± 20 mmHg (2), Consciousness Fully awake (2), Oxygen saturation SpO₂ > 92% on air (2) → Result: Aldrete 10 /10（Interpretation: Generally ready for discharge from PACU） Inputs: Activity (moves extremities) None (0), Respiration Apnoeic (0), Circulation (BP vs baseline) ± > 50 mmHg (0), Consciousness Not responding (0), Oxygen saturation < 90% with O₂ (0) → Result: Aldrete 0 /10（Interpretation: Not yet ready — continue recovery monitoring）
