Final answer:
When giving free flow oxygen with a flow inflating bag and mask, it is necessary to place the mask securely on the baby's face.
Step-by-step explanation:
When giving free flow oxygen with a flow inflating bag and mask, it is necessary to place the mask securely on the baby's face. This will ensure that the baby receives the maximum amount of oxygen from the oxygen source. If the mask is placed loosely on the baby's face, some gas may escape around the edges of the mask, reducing the efficacy of the oxygen therapy.
