Obesity hypoventilation syndrome (OHS)

Obesity hypoventilation syndrome (OHS) is defined as chronic daytime hypercapnia in obese patients (those with a BMI of > 30kg/m2) with a daytime PaCO2 of over 45 mmHg, after ruling out any other causes of hypoventilation.1

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