Fever and runny nose may also be present. These symptoms may be mild, moderate, or severe Assessment B: Breathing - Count respiratory rate, know normal ranges - Assess for increased work of breathing, retracting, flaring, grunting, head bobbing. - Listen to evaluate aeration and breath sounds C. Circulation - Assess color ( lips, mucous membranes, nail beds) - Central and peripheral pulses - Capillary refill and peripheral perfusio Croup is a common illness in young children. It can be scary for parents as well as children. Read on for more information from the American Academy of Pediatrics about croup, including types, causes, symptoms, and treatments Symptoms of Croup.
