Positive airway pressure (Paw) during high-frequency oscillatory ventilation (HFOV) increases lung volume and can lead to lung overdistention with potentially serious adverse effects. To date, no method is available to monitor changes in lung volume (DeltaVL) in HFOV-treated infants to avoid overdistention. In five newborn piglets (6-15 days old, 2.2-4.2 kg), we investigated the use of direct c...

BACKGROUND Swallowing dysfunction can lead to recurring aspiration and is frequently associated with chronic symptoms such as cough and wheezing in infants. Our objective was to describe the characteristics of infants with swallowing dysfunction, determine if pulmonary function abnormalities are detectable, and if they improve after therapy. METHODS We studied 38 infants with a history of cou...

Background: Asthma is a very common, non-communicable, chronic respiratory disease, with high incidence rate worldwide. Currently, no permanent therapeutic strategies are available for the treatment of asthma. Drugs, such as corticosteroids, β2-agonists, and anticholinergics, only temporarily reduce symptoms have various adverse effects. In this study, we investigated use fisetin, readily natur...

BACKGROUND The two most commonly used methods for the measurement of lung volumes are helium dilution and body plethysmography. Two methods have been developed which are both easier and less time consuming to perform. Mathematical modelling uses complex calculations from the flow-volume loop to derive total lung capacity (TLC), and the nitrogen balance technique uses nitrogen from the atmospher...
