In airway obstruction, tidal flows may become flow limited, especially towards the end of the tidal volume, because of dynamic compression [ 8].
The selection represents consideration of heat removal system, minimal obstruction to flow and desirable mixing effects.
The hallmark of asthma is the narrowing of the smaller airways causing obstruction to flow within the airways especially during expiration.
These modifications were employed following a guideline of good mixing and data quality, such as avoiding obstruction to flow field, avoiding hot spots, handling high viscosity and avoiding settling.
These novel fluids indicated improved heat transfer properties such as higher thermal conductivity, long-standing stability and uniformity along with the negligible obstruction in flow channels due to very small sizes and large specific areas of the nanoparticles.
The vast majority of cases of hydrocephalus are due to distinct sites of obstruction to flow of CSF.
Changes in trans-stenotic pressure gradients after coronary intervention, to remove an obstruction to flow, are a measure of the effect of the procedure.
For example, local factors, such as obstruction to flow by atherosclerosis, an arterial catheter, or thrombosis after previous arterial catheterization, could affect measurement.
Abnormal ventricular accumulation of cerebrospinal fluid (CSF), due to obstruction of flow, inadequate absorption, and/or excessive production, results in elevated intracranial pressure (ICP) and ventricular dilation.
Using injections of Iohexal tracer for CT it was shown that there were very small lateral and third ventricles and obstruction to flow from through the aqueduct and from the cortical subarachnoid space into the encysted fourth ventricle.
Passage of blood into this false lumen forces the intimal-medial layer towards the true lumen of the vessel, causing partial or full obstruction of flow, ultimately leading to an ischemic event [ 1].
