Obesity hypoventilation syndrome (OHS)

OHS is defined as chronic daytime hypercapnia in obese patients (those with a BMI of > 30kg/m)2 with a daytime PaCO2 of over 45 mm Hg, after ruling out any other causes of hypoventilation.1

As many as 90% of patients with OHS also suffer from obstructive sleep apnea (OSA).2

Equipment replacement

Equipment replacement

Take the time to educate your patients on knowing how and when to replace components of their products, and how this relates to comfort and therapy effectiveness.

Getting the most out of ventilation therapy

Adhering to therapy is critical for patients receiving noninvasive ventilation.

Why treat OHS?

Left untreated, OHS often results in right-sided heart failure, pulmonary hypertension and polyglobulia, contributing to substantial morbidity and probable early mortality.

Treatment options for obesity hypoventilation syndrome

Treatment options for obesity hypoventilation syndrome

Recommended treatment options for OHS include controlled weight loss and noninvasive ventilation.

Patient outcomes

There are many positive outcomes for OHS patients being treated with NIV including improved blood gases during the night, relieved ventilatory muscles and positive effect on lung function.
