What type of breathing pattern may be characteristic of sleep apnea?

The characteristic breathing pattern associated with sleep apnea is indeed irregular breathing with pauses. During episodes of sleep apnea, the individual experiences interruptions in breathing that can last for several seconds or even longer, typically due to an obstruction in the airway or a failure of the brain to send appropriate signals to the muscles that control breathing. This results in a pattern that is not only irregular but also features noticeable pauses, which may be followed by gasping or choking as breathing resumes.

The presence of such pauses in the breathing pattern is a defining symptom of sleep apnea, distinguishing it from other breathing patterns that do not involve intermittent cessation of breath. In contrast, rapid, shallow breathing and hyperventilation do not typically align with the apneic episodes, while consistent, rhythmic breathing indicates normal respiration, which is not characteristic of sleep apnea. Thus, recognizing the irregularity and the pauses in breathing is crucial in the diagnosis and understanding of sleep apnea.
