Hyperpnea (or hyperpnoea in British English) is increased depth of breathing when required to meet metabolic demand of body tissues, such as during or following exercise, or when the body lacks oxygen (hypoxia), for instance in high altitude or as a result of anemia.

Hyperpnea may also occur as a result of sepsis, and is usually a sign of the beginning of refractory sepsis.

Tachypnea differs from hyperpnea in that tachypnea is rapid shallow breaths, while hyperpnea is deep breaths.^[1]

Hyperpnea is not the same as hyperventilation. In hyperpnea, the increased breathing rate is desirable as it meets the metabolic needs of the body. In hyperventilation, the rate of ventilation is inappropriate for the body's needs (except in respiratory acidosis, when CO₂ needs to be breathed off). The resulting decrease in CO₂ concentration results in the typical symptoms of light-headedness, tingling in peripheries, visual disturbances etc. In hyperpnea, there are generally no such symptoms.

BACKGROUND AND OBJECTIVE: Hypoxic exercise exacerbates periodic breathing in otherwise healthy, awake humans. Interactions between sleep, exercise and hypoxic exposure have not been fully elucidated.METHODS: Fourteen men were confined 10 days to a simulated altitude of 4175 m (FI O2 = 0.139;

BACKGROUND: Eucapnic voluntary hyperpnoea (EVH) is considered an effective bronchoprovocation challenge for identifying exercise-induced bronchoconstriction (EIB). However, the reproducibility of the hyperpnoea-induced bronchoconstriction (HIB) response elicited by EVH remains unknown and was theref
