Abstract

Purpose: We investigated the effects of an internal nasal dilator on nasal airflow and cardio-respiratory capacity in adult endurance athletes, while performing controlled exhaustive physical exercise., Methods: Prospective observational study. Participants were 38 adult endurance athletes, 23 with and 15 without nasal valve compromise. Nasal patency was objectively evaluated with anterior rhinomanometry, acoustic rhinometry and peak nasal inspiratory flow (PNIF). Maximum oxygen uptake (VO2max), maximum pulmonary ventilation, time to exhaustion and total time of nasal respiration were recorded during a submaximal treadmill test. Dyspnea intensity and fatigue perception were evaluated using a labeled visual analog scale. All assessments were performed with and without the application of the internal nasal dilator., Results: All the parameters related to aerobic capacity were significantly reduced in the group of athletes with nasal valve compromise (p. <0.05 for all variables). The internal nasal dilator improved statistically significantly the nasal patency (p. <0.001), VO2max and aerobic performance and self-rating of dyspnea and fatigue (p. <0.05 for all parameters) only in athletes with nasal obstruction. PNIF correlated significantly with VO2max (rho = 0.4, p. <0.05)., Conclusions: Internal nasal dilation improves nasal patency and aerobic performance during submaximal exercise in adult endurance athletes with nasal obstruction symptoms due to nasal valve compromise., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest in relation to internal nasal dilators' manufacturer and have not received financial support. The devices delivered to the patients were offered by the authors, without further interference in the elaboration and/or planning of the experiments., (Copyright © 2023 Elsevier Inc.

Abstract

The nasal valve area has the minimal cross-sectional area of the upper airways. Nasal dilators have been found able to improve sport performance in athletes. The aim of this study was to investigate whether the use an internal nasal dilator may be able to affect respiratory pattern in a group of athletes. The use of internal nasal dilator induced a significant reduction of fatigue perception (p=0.000) and was optimally accepted. In conclusion, the present study demonstrates that Nas-air® is an internal nasal dilator able to reduce the fatigue perception and is preferred to external nasal dilator. (www.actabiomedica.it)

Abstract

The nose exerts many functions, mainly for the respiration and the olfaction and represents the first doorway for the oxygen, but also for pathogens. The present Supplement reports some clinical experiences concerning the use of a new internal nasal dilator in different settings, including nasal obstructive disorders, obstructive sleep apnea syndrome, continuous positive active pressure (CPAP), and sport activity. The outcomes support the concept that a healthy nose should be maintained ever patent and free from secretions, as impaired nasal function can significantly affect quality of life. Therefore, an “open and clean nose” contributes in a relevant way to the subjective wellness. (www.actabiomedica.it)

Abstract

The nasal valve area has the minimal cross-sectional area of the upper airways. Obstructive sleep apnea (OSA) is a common disorder. It has been reported that nasal obstruction may be associated with OSA. The aim of this study was to investigate whether the use an internal nasal dilator may be able to affect respiratory pattern in a group of patients with OSA. The use of internal nasal dilator was able to significantly reduce two relevant respiratory outcomes, such as the apnea-hypopnea index and the oxygen desaturation index, notably there was also a positive trend for the reduction of total sleep time with HbO2

Abstract

Snoring is a common symptom. The nasal valve area has the minimal cross-sectional area of the upper airways. So, nasal dilation may significantly reduce resistance to airflow and consequently could reduce snoring. Mechanical dilators may be used: they are external or internal. Nas-air® is a new internal nasal dilator. It was compared to a nasal strip (Rinazina Breathe Right®) in 41 outpatients who snore in an open study conducted in clinical practice. Snoring duration, assessed by smartphone, and visual analogue scale for the perception of sleep quality were measured before and during Nas-air® or nasal strip use. A significant reduction of snoring time and an improvement of sleep quality were achieved by wearing both devices. However, Nas-air® was effective in a larger number of patients and induced a better sleep quality than nasal strip. In conclusion, the present study demonstrates that Nas-air® is an internal nasal dilator able to reduce snoring time and to improve sleep quality, and may be preferred to the nasal strip by snoring patients.
