 An acronym that we sometimes see used in the clinical setting, more likely in the paramedic or in the first responder world is AFPU, A-V-P-U. And that is a quick assessment of the patient's mental status, A, meaning alert, V, being verbal, so the patient responds by speaking, P, responds to painful stimuli, and then U, for unresponsive. It is a very brief assessment of the patient's neurologic function and should not be used instead of the Glasgow Coma Scale, which entails much more of the patient's neurologic status, but is a very nice, quick clinical tool to assess the patient's mental state.
