Definition

1. Noun:
   • A physical condition characterized by an abnormally high level of carbon dioxide in the circulating blood. This is a medical term for excessive carbon dioxide in the bloodstream, which can disrupt the body's acid-base balance and is often associated with respiratory insufficiency.

Usage

• The term "hypercapnia" is used in medical and clinical contexts to describe a pathological state. It is typically discussed in relation to its causes (e.g., lung disease, hypoventilation), symptoms (e.g., shortness of breath, confusion), and treatment (e.g., improved ventilation).

Examples

• Noun:
  • The patient's sleep apnea led to chronic hypercapnia.
  • Severe hypercapnia can result in carbon dioxide narcosis, a state of decreased consciousness.
  • Mechanical ventilation is often required to correct acute hypercapnia.

Advanced Usage

• "Permissive hypercapnia": A controlled strategy in mechanical ventilation where higher than normal levels of carbon dioxide are allowed to minimize lung injury from high ventilator pressures.
  • The ICU team used a strategy of permissive hypercapnia to protect the patient's injured lungs.

Variants and Related Words

• Hypercapnic (adj): Relating to or affected by hypercapnia.
  • The patient was in a hypercapnic state.

Synonyms

• Hypercarbia: A synonymous medical term for an elevated level of carbon dioxide in the blood.

Noun

1. the physical condition of having the presence of an abnormally high level of carbon dioxide in the circulating blood
