The main goals of treatment for OHS patients are as follows:

• Normalise arterial carbon dioxide tension (PaCO₂ 45 mm Hg)
• Prevent hypoxemia during sleep and wakefulness
• Prevent erythrocytosis, pulmonary hypertension, and respiratory failure
• Relieve hypersomnia and altered mentation

Treatment with NIV helps to achieve these goals, and has been widely observed to be the ideal treatment for OHS. ¹
