Richmond Agitation-Sedation Scale (RASS) is a medical scale used to measure the agitation or sedation level of a person. It was developed with efforts of different practitioners, represented by physicians, nurses and pharmacists. [1] [2]
Procedural sedation and analgesia (PSA) is a technique in which a sedating/dissociative medication is given, usually along with an analgesic medication, in order to perform non-surgical procedures on a patient. The overall goal is to induce a decreased level of consciousness while maintaining the patient's ability to breathe on their own.
Close monitoring by the anesthesia provider will sometimes be provided, to help keep the patient comfortable during a medical procedure, along with other drugs to help relax the body.
