Hyperpnea is when increased breathing is required to meet demand, as during and following exercise or when the body lacks
oxygen (
hypoxia), for instance in high altitude or as a result of
anaemia. 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 rapid deep breaths.
