What RASS target is recommended for most ICU patients?

RASS -2 to 0 (light sedation to alert) is recommended for most mechanically ventilated ICU patients; deep sedation (RASS -3 to -5) is associated with longer MV duration, delirium, and mortality.

What is RASS scale range and its meaning?

RASS +4: combative; +3: very agitated; +2: agitated; +1: restless; 0: alert and calm; -1: drowsy (response to voice); -2: light sedation (brief eye opening to voice); -3: moderate (movement to voice); -4: deep (no voice, moves to physical); -5: unarousable.

How should dexmedetomidine be titrated using RASS?

Dexmedetomidine 0.2-1.5 mcg/kg/h targets RASS -2 to 0; preferred for patients requiring awakening for assessment; reduces delirium vs benzodiazepines; bradycardia and hypotension are dose-limiting side effects.

What is the ABCDEF bundle and RASS role?

ABCDEF bundle: A=Assess/treat pain; B=Both SAT/SBT; C=Choice of sedation (light preferred); D=Delirium assess (CAM-ICU); E=Early mobility; F=Family engagement; RASS guides C and B components.

How does propofol compare with midazolam for ICU sedation?

Propofol allows faster awakening and extubation, reduces ICU stay; midazolam is cheaper but accumulates in obese/elderly patients causing prolonged sedation; both associated with delirium at deep sedation levels.

Richmond Agitation-Sedation Scale (RASS) Calculator

Calculates the Richmond Agitation-Sedation Scale score (-5 to +4) to assess sedation and agitation levels in ICU patients, guiding propofol/midazolam/dexmedetomidine titration to target RASS -2 to 0.
