Hi doctors, was just wondering what is carbon dioxide narcosis in relation to COPD or chronic obstructive pulmonary disease?

Carbon dioxide... Carbon dioxide levels can elevate in COPD patients due to the inability to ventilate properly. This increased carbon dioxide level can lead to symptoms that are similar to acutely taking narcotics which has lead to the expression carbon dioxide narcosis. Symptoms include lethargy, confusion, disorientation, decreased sensations, etc.
