Patient outcomes

OHS patient outcomes ResMed


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

  • 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 NIV.3


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

More OHS

Equipment replacement
Educate patients on the importance of timely equipment replacement and how critical it is to the success of their sleep apnea therapy.
Getting the most out of ventilation therapy for OHS patients
Adhering to therapy is critical for patients receiving noninvasive ventilation.
Treatment options for OHS
Recommended treatment options for OHS include controlled weight loss and noninvasive ventilation.
