Web3 de ago. de 2024 · Conclusions: In patients with congenital diaphragmatic hernia, resistance levels of > 400 cmH 2 O·kg/L/s may indicate high airway resistance and suggest greater alveolar vibration attenuation. When respiratory-system resistance reaches over 400 cmH 2 O·kg/L/s, it may be an optimal time for switching from high frequency … WebHigh driving pressures and prolonged inspiratory times significantly increased gas trapping. This effect was most pronounced when both airway resistance and pulmonary …
Airway resistance can also vary between inspiration and expiration: In emphysema there is destruction of the elastic tissue of the lungs which help hold the small airways open. Therefore during expiration, particularly forced expiration, these airways may collapse causing increased airway resistance. Web13 de mar. de 2024 · 1 INTRODUCTION. Nasal airway obstruction (NAO) is a highly prevalent disorder affecting the upper airway system. NAO can lead to an overall decline in health-related quality of life (QOL) due to its burdensome symptoms, including congestion, stuffiness, headache, fatigue, sleep disturbance, daytime sleepiness, snoring, and …
