NIV for obesity hypoventilation syndrome

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
