The Ramsay Sedation Scale (RSS) was the first scale to be defined for sedated patients and was designed as a test of rousability. The RSS scores sedation at six different levels, according to how rousable the patient is. It is an intuitively obvious scale and therefore lends itself to universal use, not only in the ICU, but wherever sedative drugs or narcotics are given. It can be added to the pain score and be considered the sixth vital sign.
