This document provides guidance on performing a baseline medical assessment of a patient, including vital signs and SAMPLE history. It describes how to evaluate respiratory rate and sounds, pulse rate, blood pressure, temperature, skin signs, pupils, and collect a SAMPLE history which inquires about the patient's signs/symptoms, allergies, medications, pertinent medical history, last oral intake, and events leading to the present illness or injury. Performing a thorough baseline assessment establishes the patient's initial medical status and provides information to guide care.
