Rapid, shallow breathing, also called tachypnea or tachypnoea (Greek for "rapid breathing") is the process of taking more than normal air into and expelling it from the lungs. Hyperventilation is a condition in which a person suddenly starts to breathe very quickly upsetting the balance between breathing in oxygen and breathing out carbon dioxide. For adult humans at rest, tachypnea is indicated by a ventilatory rate greater than 20 breaths per minute.
Average respiratory rates:
Newborns: 44 breaths per minute
Infants: 20–40 breaths per minute (over 50 if sick)
Preschool children: 20–30 breaths per minute (over 40 if sick)
Older children (5-8): 16–25 breaths per minute (over 30 if sick)
Healthy Adults: 12–18 breaths per minute (up to 70 if stressed or exercising)
Adults with Asthma: 24-30 breaths per minute (12-15 l/min)
Adults with Heart Disease : 28-32 breaths per minute
Adults with Diabetes: 20-40 breaths per minute
