What does hypercapnia refer to in terms of blood chemistry?

• A. Excessive carbon monoxide
• B. Excessive carbon dioxide
• C. Deficient oxygen
• D. Deficient carbon dioxide

Answer: (B)

Hypercapnia specifically refers to an elevated level of carbon dioxide (CO2) in the blood. This condition arises when there is an imbalance in the body’s ability to remove CO2, often due to respiratory issues, hypoventilation, or other conditions that impair gas exchange in the lungs. As carbon dioxide is a byproduct of cellular metabolism, its accumulation in the bloodstream can lead to respiratory acidosis, where the blood becomes more acidic due to the increased concentration of CO2. When hypercapnia occurs, it can have various physiological effects, including respiratory drive alteration and potential impacts on the central nervous system. The body senses increased CO2 levels through chemoreceptors, which then stimulate breathing to expel excess carbon dioxide. Thus, understanding hypercapnia is crucial in assessing and managing respiratory health.
