Abstract
Delayed resistance nasal devices include an airflow resistor that is configured to normally have a higher resistance to exhalation than inhalation, but the higher resistance to exhalation may be suspended, or delayed by activation of an airflow resistor bypass. Activation of an airflow resistor bypass bypasses or decreases the effect of the airflow resistor on nasal airflow through the nasal device, decreasing the resistance to exhalation. Methods of decreasing, suspending, or delaying the onset of the inhibition of the exhalation through such nasal respiratory devices are described.
