Why is treatment important?

Studies have shown that OHS can be treated effectively by following a controlled weight loss program1 and starting positive airway pressure or noninvasive ventilation (NIV).1 Your physician may also monitor your condition using the following:

  • An arterial blood gases test*
  • A lung function test
  • A polysomnography test (overnight sleep study)
  • Chest x-rays

Noninvasive ventilation (NIV)

For OHS, the aim of ventilation is to improve the exchange of oxygen and carbon dioxide between the blood and the air in your lungs2 and support your respiratory system so you don’t need to work so hard to breathe effectively.3 Pressurised air is delivered from a small device that sits on your bedside table, to a mask that you wear over your mouth and/or nose. NIV is a common treatment option for OHS.1 ResMed’s ventilation options to treat OHS are as follows:
