Tachypnea

ICD-10	R06.0
ICD-9	786.06

Tachypnea (or "tachypnoea") (Greek: "rapid breathing") is characterized by rapid breathing.^[1]

It is not identical with hyperventilation - tachypnea may be necessary for a sufficient gas-exchange of the body, for example after exercise, in which case it is not hyperventilation.

Tachypnea differs from hyperpnea in that tachypnea is rapid shallow breaths, while hyperpnea is rapid deep breaths.

Lungs and breathing activity Commonly confused terminology view • talk • edit

Dyspnea - Shortness of breath

Hyperventilation - increased breathing that causes CO2 loss

Hyperpnea - faster and/or deeper breathing

Tachypnea - increased breathing rate

Hyperaeration/Hyperinflation - increased lung volume

Tachypnea can also be a symptom of carbon monoxide poisoning in which oxygen delivery to the tissues and organs is blocked causing hypoxia and direct cellular injury.
