This study evaluates labeling comprehension, ease of use and effectiveness of a new device for nasal and sinus irrigation and/or aspiration. The device is currently cleared for professional use and home use with a prescription. This is a usability study to demonstrate that this device is appropriate for home use.
Nasal congestion is an important complication of viral upper respiratory infections in young children. It can lead to poor eating, sleeping and breathing. Recently, the FDA recommended against using over-the-counter cold remedies in young children because of inefficacy and occasional dangerous side effects. A commonly recommended non-drug solution for nasal congestion is nasal suctioning. This can be effective but currently available methods have been found to be awkward, uncomfortable and ineffective.
The studied device has potential for making nasal suctioning easy to perform in the home setting, especially in young children. It is already FDA cleared for professional use and this study was developed to demonstrate that it is appropriate for the home as well. This would be significant as it would allow parents a strategy of clearing their child's nose without drugs.
The device is automatic and handheld that can irrigate and/or aspirate the nasal cavity with hospital-grade suction. The handle houses a pump that can achieve air flows known to be effective for infant nasal suctioning in the hospital. A disposable wash-head is placed on top. It has an irrigation chamber with 0.9% saline and another chamber for collecting the aspirated nasal contents. The unit operates from a single bi-functional button.
Several key safety features have been built in such as: a tip that is shaped to maximize the seal but prevent intrusion into the nose; an irrigation function that delivers an optimal volume but prevents flooding the nasal cavity; and a pump that can deliver suction known to be effective in the hospital but whose safety valve does not allow it to rise above dangerous levels.
Participants were parents of children who have nasal congestion for whom nasal suctioning is traditionally recommended. They were asked to review the instruction manual of the device, and then use it on their children.
The primary outcome was proper use of device that was precisely defined. Additionally, subjective efficacy of mucus removal, evidence of adverse events and understanding of the device's user manual were also measured.

Fluid obtained by irrigation or washout of the nasal cavity and NASAL MUCOSA. The resulting fluid is used in cytologic and immunologic assays of the nasal mucosa such as with the NASAL PROVOCATION TEST in the diagnosis of nasal hypersensitivity.
The proximal portion of the respiratory passages on either side of the NASAL SEPTUM. Nasal cavities, extending from the nares to the NASOPHARYNX, are lined with ciliated NASAL MUCOSA.
Application of allergens to the nasal mucosa. Interpretation includes observation of nasal symptoms, rhinoscopy, and rhinomanometry. Nasal provocation tests are used in the diagnosis of nasal hypersensitivity, including RHINITIS, ALLERGIC, SEASONAL.
Diagnostic measurement of the nose and its cavity through acoustic reflections. Used to measure nasal anatomical landmarks, nasal septal deviation, and nasal airway changes in response to allergen provocation tests (NASAL PROVOCATION TESTS).
