A normal respiratory rate for an adult at rest is 8 to 16 breaths per minute, while for an infant, the normal rate is up to 44 breaths per minute.
Tachyponea is a term used by your health care provider to describe breathing if it is too fast, particularly if you have rapid, shallow breathing from a pneumopathy or other health cause.
The term hyperventilation is usually used if you are taking deep, rapid breaths. This may be due to lung disease or anxiety or panic. The terms are sometimes used interchangeably.
Rapid and superficial breathing has many possible causes, including:
Blood clot in an artery in the lung
Chronic obstructive pulmonary disease (COPD) and other chronic lung diseases
Infection in the smallest airways of the lungs in children (Bronchiolitis)
Pneumonia or another lung infection
Transient Tachyponea of the newborn
Anxiety and panic
Other serious lung diseases.
