Daytime hypercapnia may also be present. Sleep related hypoxemia may be severe. Patients can either be asymptomatic or present with complaints of dyspnea, chest tightness, or fatigue.Note: A definitive diagnosis requires objective evidence based on polysomnography with carbon dioxide (CO2) monitoring (by arterial, end-tidal or transcutaneous measures) in the presence of a medical condition that is judged to be causing the symptoms.
