Richmond Agitation-Sedation Scale (RASS)

Score agitation and sedation depth using the RASS (-5 to +4). Target RASS -1 to 0 for most ICU patients to reduce ventilator days, delirium, and ICU-acquired weakness.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Score agitation and sedation depth using the RASS (-5 to +4). Target RASS -1 to 0 for most ICU patients to reduce ventilator days, delirium, and ICU-acquired weakness

Each component has a specific meaning:

  • RASS (-5 — The rass (-5 recorded for the scenario being assessed.

Note: Interpret the rass result against the thresholds and context described above.

How to Use

Enter the RASS (-5 for the scenario you are assessing. Score agitation and sedation depth using the RASS (-5 to +4). Target RASS -1 to 0 for most ICU patients to reduce ventilator days, delirium, and ICU-acquired weakness. Use the rass result to inform your calculation.
