Application of Dual Mask for Postoperative Respiratory Support in Obstructive Sleep Apnea Patient

In some conditions continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BIPAP) therapy alone fails to provide satisfactory oxygenation. In these situations oxygen (O(2)) is often being added to CPAP/BIPAP mask or hose. Central sleep apnea and obstructive sleep apnea (OSA) are often present along with other chronic conditions, such as chronic obstructive pulmonary disease (COPD), congestive heart failure, pulmonary fibrosis, neuromuscular disorders, chronic narcotic use, or central hypoventilation syndrome. Any of these conditions may lead to the need for supplemental O(2) administration during the titration process. Maximization of comfort, by delivering O(2) directly via a nasal cannula through the mask, will provide better oxygenation and ultimately treat the patient with lower CPAP/BIPAP pressure.
