What is hypercapnia?

Hypercapnia refers specifically to elevated carbon dioxide levels in the blood. This condition occurs when there is an imbalance between the production and elimination of carbon dioxide in the body, often due to respiratory issues. An increase in carbon dioxide can lead to respiratory acidosis, where the blood becomes more acidic, impacting various bodily functions.

Understanding hypercapnia is crucial in the context of respiratory health and management, especially during polysomnography or sleep studies. Conditions like sleep apnea can lead to periods of elevated carbon dioxide levels due to impaired breathing, making it a significant concern for polysomnographic technologists. In assessing patients, recognizing the signs and implications of hypercapnia can lead to better diagnosis and management of sleep-related breathing disorders.
