Airway obstruction during exercise and isocapnic hyperventilation in asthmatic subjects.
We compared pulmonary mechanics measured during long-term exercise (LTX = 20 min) with long-term isocapnic hyperventilation (LTIH = 20 min) in the same asthmatic individuals (n = 6). Peak expiratory flow (PEF) and forced expiratory volume in 1 s (FEV(1)) decreased during LTX (-19.7 and -22.0%, respectively) and during LTIH (-6.66 and 10. 9%, respectively). In contrast, inspiratory pulmonary res...

متن کاملUpper airway obstruction in children.
Poiseuille’s law is central to the understanding and management of all airway obstructions in children, with the clinical impact of even a small reduction in radius being compounded by the inverse relationship of the resistance to the radius to the power 4. Indeed deterioration from a ‘mild’ obstruction to life threatening airway compromise may be heralded by slight decrease in airway diameter ...
متن کاملRespiratory impedance response to a deep inhalation in asthmatic children with spontaneous airway obstruction.
The aim of the study was to determine whether the bronchomotor effect of a deep inhalation (DI) may be detected during tidal breathing in asthmatic children with spontaneous airway obstruction (AO). Two groups of children aged 5-15 yrs were studied. AO was mild in group 1 (n=12, forced expiratory volume in one second (FEV1) > or = 75% predicted) and moderate-to-severe in group 2 (n=9, FEV1 > or...
