title: An evaluation of a novel mask in four patients with obstructive sleep apnea and overlap syndromes.
abstract: We present four cases of adults with obstructive sleep apnea in whom positive airway pressure therapy alone failed to provide adequate oxygenation. We have previously reported the use of dual mask for ventilatory support of a patient postoperatively (Porhomayon et al., 2013). Here, we report an evaluation of the dual mask in four patients with overlap syndromes. Application of dual mask provided adequate oxygenation with lower continuous positive airway pressure (CPAP)/bilevel positive airway pressure (BIPAP) pressure levels.
