Croup
It is important to keep children with croup as calm as possible. Children often are given steroids, but epinephrine is used in severe cases. If the amount of blood oxygen is under 92%, the child needs oxygen. People with  severe croup can be hospitalized for observation. If oxygen is needed, "blow-by" administration (holding an oxygen source near the face of the child) is better than an oxygen mask, because it is less likely to upset a child than an oxygen mask is. With treatment, less than 0.2% of people need endotracheal intubation(a tube placed into the airway).
