چکیده

OBJECTIVE To investigate effects of the nose dilating devices on nasal anatomy and breathing in healthy subjects. MATERIALS AND METHODS 27 healthy subjects were tested when using the Breathe Right nasal strip or the Nozovent dilator. Posterior rhinomanometry, acoustic rhinometry, and a subjective evaluation were used as methods. RESULTS Both devices significantly increased the minimum cross-sectional area of the nasal valve and decreased nasal resistance. The Nozovent dilator proved to be significantly more effective in reducing nasal resistance than the Breathe Right nasal strip. CONCLUSIONS Nose dilating devices, the Breathe Right nasal strip and the Nozovent dilator, can be used to reduce nasal resistance. More studies are needed to evaluate the usefulness of the devices for patients with chronic obstruction for any reason in the valve area.

Nasal airflow dynamics: mechanisms and responses associated with an external nasal dilator strip.

The adhesive external nasal dilator strip (ENDS) is widely advocated for prevention of snoring and promotion of nasal breathing during exercise. In the present study, the effects of the ENDS on nasal airflow resistance (Rn) in normal subjects were examined and factors determining individual responses to the ENDS explored. Using posterior rhinomanometry, 20 healthy Caucasian adults (10 males, 10...

Nasal resistance and flow resistive work of nasal breathing during exercise: effects of a nasal dilator strip.

Using posterior rhinomanometry, we measured nasal airflow resistance (Rn) and flow-resistive work of nasal breathing (WONB), with an external nasal dilator strip (ENDS) and without (control), in 15 healthy adults (6 men, 9 women) during exclusive nasal breathing and graded (50-230 W) exercise on a cycle ergometer. ENDS decreased resting inspiratory and/or expiratory Rn (at 0.4 l/s) by >0.5 cmH(...

Evaluation of the Efficacy of a Nasal Dilator in Habitual-Snorer Patients

I t has been suggested that conditions associated with nasal obstruction predispose to the development of snoring and OSA (1,2). Some authors indicated that the nose accounts for approximately half of the total airway resistance to airflow (3). Nasal obstruction may contribute to an increase in snoring and sleep apnea frequency and severity (4). For this reason, nasal dilators have been propose...

Combined effects of a nasal dilator and nasal prongs on nasal airflow resistance.

STUDY OBJECTIVES Nasal prongs (NPs), when used to assess nasal flow, can result in dramatic increases in nasal airflow resistance (NR). The aim of this study was to investigate whether the NP-induced increases in NR could be corrected by the simultaneous use of an internal nasal dilator (ND). DESIGN NR was estimated by posterior rhinomanometry, in the basal state (NRb), and while breathing wi...
