Average Volume-assured Pressure Support as Rescue Therapy in Obesity Hypoventilation Syndrome

It remains unclear whether CPAP therapy should be prescribed if significant hypoxemia persists during CPAP titration, despite optimization of upper airway obstructive events, if maximum CPAP pressure is reached. The goal was to examine the effects of 6 months of home AVAPS therapy in patients with obesity hypoventilation syndrome as a potential option for patients who failed CPAP titration due to persistent hypoxemia.
