Definition

Noun: * Hyperpnea refers to an increased depth and rate of breathing. It is a physiological response that occurs normally during or after physical exertion to meet the body's higher demand for oxygen and to expel more carbon dioxide. It can also occur abnormally as a symptom associated with fever or certain medical disorders.

Usage

Hyperpnea describes a specific pattern of breathing that is both deeper and faster than normal (eupnea). It is a neutral medical term used to describe a respiratory state. * It is used to discuss a normal, expected physiological process. * It is also used in a clinical context to describe a sign or symptom of an underlying condition.

Examples

• The hyperpnea observed after the sprint was a normal adjustment to the metabolic demands of the exercise.
• A state of hyperpnea is common in patients with high fever as the body attempts to dissipate heat.
• The doctor noted the patient's hyperpnea as a potential indicator of a metabolic acidosis.

Advanced Usage

• Hyperpnea is often contrasted with hyperventilation. While both involve rapid breathing, hyperventilation specifically leads to a decrease in arterial carbon dioxide levels (hypocapnia). Hyperpnea can be a component of hyperventilation but can also occur without altering blood gas levels (e.g., during exercise).
• The term can be used in specialized fields like exercise physiology and pulmonology.

Variants and Related Words

• Hyperpneic (adjective): Pertaining to or characterized by hyperpnea.
  • The patient exhibited a hyperpneic breathing pattern.

Synonyms

• Increased ventilation
• Deep and rapid breathing
• Tachypnea (specifically refers to rapid breathing, but not necessarily increased depth)

Antonyms

• Hypopnea: Abnormally shallow or slow breathing.
• Apnea: The temporary cessation of breathing.
• Eupnea: Normal, quiet, resting breathing.

Noun

1. energetic (deep and rapid) respiration that occurs normally after exercise or abnormally with fever or various disorders
