The Eagle 2 series of disposable single-patient use, oro-nasal masks is meant to administer oxygen or other breathing gases into the upper airway for short-term or emergency applications of non-invasive respiratory support or ventilation in hospital, transport vehicle, institutional or other clinical settings. It has a supplemental, membrane-sealed port for use during insertion of a bronchoscope or other endoscopic device into the patient’s airway while still administering oxygen and other breathing gases.
