Evaluation and Management of Obesity Hypoventilation Syndrome
Key Points
Key Points
OHS is the most severe form of obesity-induced respiratory compromise and leads to serious sequelae, including increased rates of mortality, chronic heart failure, pulmonary hypertension, and hospitalization due to acute-on-chronic hypercapnic respiratory failure, among others.
While the definition of OHS suggests a diurnal pathology, polysomnography or sleep respiratory polygraphy is required to determine the pattern of SDB and hypoventilation (obstructive or non-obstructive), to tailor treatment, and to establish the optimal settings of positive airway pressure (PAP) therapy.
PAP has become the primary management option for controlling SDB and reversing awake hypoventilation in patients with OHS.
