Hypercarbic respiratory failure is characterized by an inability to effectively remove carbon dioxide (CO2) from the body, leading to elevated levels of CO2 in the bloodstream, a condition known as hypercapnia. This often occurs due to conditions that impair the mechanics of breathing, the ventilatory capacity, or the central nervous system's response to increase carbon dioxide levels.

When the body cannot rid itself of CO2, it results in respiratory acidosis, which can cause various physiological disturbances. This condition may arise from conditions such as chronic obstructive pulmonary disease (COPD), severe asthma, or neurological disorders that affect the respiratory muscles or brain's respiratory centers.

While other options touch on aspects of respiratory function, they do not specifically address the core issue of hypercarbic respiratory failure, which is primarily associated with the impaired removal of CO2.
