The disclosed devices and methods provide one or more sensors associated with a nasal insert to provide data on respiratory health from within a patient's nasal passage. The nasal insert may simply be a vehicle for carrying one or more sensors, or the nasal insert itself may form part of the treatment. For example, the nasal insert may be used to increase airflow through the nasal passages. The nasal insert can contain a bio-sensor that may be affixed to an internal or external surface of the insert, be embedded partially or fully in an internal or external surface of the insert, or may pass through an internal or external wall of the nasal insert. In addition, the insert may include grooves that can be used to attach a sensor to the insert, for example, in place of or in conjunction with a filter.
