Pulmonary Function Measurement in Noninvasive Ventilatory Support: Obesity Hypoventilation Syndrome

Obesity hypoventilation syndrome is a clinical condition characterized by the association of alveolar hypoventilation, hypercapnia, and daytime sleepiness in obese patients without any other causes of chronic hypercapnia. The most effective method in treatment is positive pressure ventilation including noninvasive ventilation and continuous positive airway pressure. Close monitoring of the patients’ pulmonary function is important for the effectiveness of treatment.
