Chapter 3: Sleep-Related Breathing Disorders


There are two sub-types of SRHS:

  • SRHS may be primary, possibly related to blunted central or peripheral chemo-responsiveness, or due to a congenital condition.
  • SRHS may also be comorbid with certain medical conditions that cause the impairment of gas exchange, such as Chronic Obstructive Pulmonary Disease (COPD) and emphysema; depression of the central respiratory drive (e.g., opioid-induced); or other neurologic, neuromuscular, or chest wall disorders or abnormalities that impair a person’s ability to breathe.1
