Abstract

Described herein are nose-reduced nasal devices configured to reduce or eliminate noises associated with use of a nasal device. These noise-reduced nasal devices include a flap valve and a noise-reduction feature that is a noise-reduction element, a noise-reduction flap valve, or both. The noise-reduction feature typically prevents the flap valve from oscillating or vibrating and producing an audible sound during use, particularly during inhalation through the device. The method and devices described herein may prevent the flap, and particularly the edge region of the flap face or tip of the flap, from oscillating during inhalation. Also described herein are adjustable-resistance nasal respiratory devices which may include one or more resistance-modifying members for modifying the resistance of a nasal device. The adjustable- resistance nasal respiratory devices described herein may include a control or controls for adjusting the resistance to expiration. Methods of adjusting the resistance of a nasal device are also described.
