average normals for respirations
Normal respiration rate in adults is 12 breaths/min. Normal breathing, as we discussed, is strictly nasal (in and out), mainly diaphragmatic (i.e., abdominal), slow (in frequency) and imperceptible (or small/shallow in its volume).
For children from the age of one to five years old, normal respiration is 20 to 30 breaths per minute, while children who are from six to twelve years old should have a normal respiratory rate that ranges from 12 to 20 breaths per minute.
