hyperpnea
Học thuậtThân thiện
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
- energetic (deep and rapid) respiration that occurs normally after exercise or abnormally with fever or various disorders
