What condition is characterized by episodes of decreased breathing and high carbon dioxide levels?

Sleep-Related Hypoventilation is marked by episodes of insufficient ventilation, which leads to an increase in carbon dioxide levels in the blood. This condition occurs during sleep and is primarily characterized by a reduction in the overall breathing rate, causing hypercapnia (high carbon dioxide) and potential complications such as hypoxemia (low oxygen levels).

Unlike Obstructive Sleep Apnea, which involves intermittent blockages of the upper airway leading to breathing cessation and often includes episodes of oxygen desaturation, sleep-related hypoventilation specifically pertains to inadequate air exchange rather than obstructions.

Nightmare Disorder and Restless Leg Syndrome are unrelated to breathing rates or carbon dioxide levels. Nightmare Disorder relates to sleep disturbances with vivid, distressing dreams, while Restless Leg Syndrome involves uncomfortable urges to move the legs, particularly during rest or inactivity, but does not involve altered breathing patterns or carbon dioxide retention.
