Web8 de jun. de 2015 · Neonatal respiratory physiology is characterised by higher chest wall compliance, lower lung compliance and increased airway resistance. Work of breathing is increased, even accounting for the increase in respiratory demand and metabolic rate. Generally, a normal resting respiratory rate is around 30-50. Gas exchange is also … WebHigh driving pressures and prolonged inspiratory times significantly increased gas trapping. This effect was most pronounced when both airway resistance and pulmonary …
Web22 de jul. de 2015 · Background Airway resistance (RAW) and specific airway conductance (sGAW) are measures that reflect the patency of airways. Little is known of the variability of these measures between different lung diseases. This study investigated the contribution of RAW and sGAW to a diagnosis of obstructive airways disease and their … Web12 de abr. de 2024 · Ozone is strong oxidizing agent that is applied in aqueous form for sanitation. However, ozonated water is unstable and has a short half-life. Ultrafine bubble technology is promising to overcome these issues.

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.
