RASS (Sedation–Agitation)

Richmond Agitation–Sedation Scale.

Education and reference only. Not a substitute for clinical judgement, local policy or product labelling. Always verify before clinical use. Values are calculated in your browser and never stored.

When to use

Use to assess level of sedation or agitation in ventilated/critically ill patients and to titrate sedation to target.

Why use

It standardises sedation assessment and supports goal-directed sedation.

Advice

A common target for ventilated patients is 0 to −2. Deep sedation (−4/−5) is linked to worse outcomes; reassess sedation regularly.
