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
