Abstract

Described herein are nasal devices. In particular, layered nasal respiratory devices are described. Layered nasal device may include a layered airflow resistor that is configured to resist airflow in a first direction more than airflow in a second direction and that includes a flap valve adjacent to a flap valve limiting layer and an adhesive holdfast layer that is configured to secure the layered airflow resistor in communication with the subject's nasal cavity. Methods of using and methods of assembling layered nasal device are also described.
