hypocapnia

Thân thiện

A patient experiencing hypocapnia breathes rapidly into a paper bag.

Definition

Noun: A medical condition characterized by an abnormally low level of carbon dioxide (CO₂) in the blood. It typically results from hyperventilation (excessively deep or rapid breathing), which causes too much CO₂ to be expelled from the lungs.

Usage and Examples

Noun: * The patient's anxiety attack led to hypocapnia, causing dizziness and tingling in the fingers. * Hypocapnia is a common consequence of breathing at a high altitude. * The doctor identified the lightheadedness as a symptom of acute hypocapnia.

Advanced Usage

• "Induced hypocapnia": Sometimes deliberately induced in a controlled medical setting, such as during certain types of surgery, to reduce pressure inside the skull.
• "Chronic hypocapnia": A prolonged state of low blood CO₂, which can lead to the kidneys compensating by excreting more bicarbonate, altering the body's acid-base balance.

Variants and Related Words

• Hypercapnia (noun): The opposite condition; an excess of carbon dioxide in the blood.
• Hypocapnic (adjective): Relating to or suffering from hypocapnia.
  • The patient was in a hypocapnic state.

Synonyms

• Acapnia (a largely synonymous, though less common, medical term).

Antonyms

• Hypercapnia

Related Medical Concepts

• Alkalosis: A condition of reduced blood acidity, which often accompanies hypocapnia because carbon dioxide dissolved in blood forms carbonic acid. Low CO₂ leads to respiratory alkalosis.
• Hyperventilation: The most common cause of hypocapnia.
