Patient outcomes

There are many positive outcomes for OHS patients being treated with NIV, including:

  • Improved blood gases during the night, which in turn improves them during the day
  • Relieved ventilatory muscles1
  • Positive effect on lung function, especially when residual capacity is increased2
  • Lower mortality compared to OHS patients not treated with NIV3

Special considerations

  • OHS patients require a high level of medical care and are more likely to be hospitalized. (8.6 times higher than for general population control subjects).3
  • OHS patients have been found to make 11.2 physician visits per year compared to 5.7 visits for obese-only patients.3
  • Effective treatment of OHS has shown a significant reduction in physician fees and a 68.4% decrease in annual hospitalization days.3
