Flow-limitation and upper airways.
We read with interest in the February 1995 issue of The European Respiratory Journal the article by KOULOURIS et al. [1] "A simple method to detect expiratory flowlimitation during spontaneous breathing". The authors applied negative pressure at the mouth (-5 cmH2O) during a tidal expiration (NEP) to 22 patients with chronic obstructive lung disease. They conclude that this provides a simple, n...
متن کاملConvective dispersion during steady flow in the conducting airways of the human lung.
The adverse health effects of inhaled particulate matter from the environment depend on its dispersion, transport, and deposition in the human airways. Similarly, precise targeting of deposition sites by pulmonary drug delivery systems also relies on characterizing the dispersion and transport of therapeutic aerosols in the respiratory tract. A variety of mechanisms may contribute to convective...
متن کاملRipple Morphology under Oscillatory Flow
Our ultimate long-term goal is to further the understanding of bed morphology and sediment dynamics under oscillatory flows. Experiments will be conducted to expand existing data sets of sand bed morphology and evolution in large scale laboratory facilities under controlled flow conditions. Based on this additional insight from the improved data set we aim to advance presently available tools f...
متن کاملAugmentation of blood flow in limbs with occlusive arterial disease by intermittent calf compression.
PURPOSE This study was designed to investigate the effect of intermittent calf compression on popliteal arterial blood flow and to see how flow is influenced by position of the subject and by arterial blood pressure at the ankle. METHODS Volume flow in the popliteal artery of subjects in the sitting and prone positions was measured with duplex ultrasonography before inflation and immediately ...
متن کاملInstantaneous sediment transport model for asymmetric oscillatory sheet flow
On the basis of advanced concentration and velocity profiles above a mobile seabed, an instantaneous analytical model is derived for sediment transport in asymmetric oscillatory flow. The applied concentration profile is obtained from the classical exponential law based on mass conservation, and asymmetric velocity profile is developed following the turbulent boundary layer theory and the asymm...
