Accidental loss of food or liquids into the airway while eating or drinking is perhaps the most clinically significant consequence of dysphagia. Although videofluoroscopic recording of swallowing is the current gold standard for identifying and determining remediation for aspiration, results are gen …
Pulmonary aspiration complicates between 1 in 900 to 1 in 10 000 general anaesthetics,1 dependent on risk factors. All novice anaesthetists in the UK are taught to consider the risk of aspiration and to modify their anaesthetic technique accordingly. The prevention of aspiration remains a cornerstone of anaesthetic practice.
During anesthesia induction, 76.0% of regurgitation events developed aspiration, and the remaining 24.0% had regurgitation without aspiration. But prior to anesthesia induction, only 10.0% ...

In such conditions, the rocks could fail by the mechanism of progressively self-localizing thermal runaway(1), whereby ductile deformation in shear zones leads to heating, thermal softening and ...
These cases not only illustrate the dangers of moving the patient during the emergence phase but also how many aspiration events go unreported, assuming these happened some time ago. We agree that one of the keys to safe use of the LMA is to ensure that the patient is adequately anaesthetized, and that the easiest way of avoiding the problems ...

The working hypothesis of this proposed research is that dust generation during grain handling depends on the surface characteristics such as adhesion and surface energy. Our preliminary studies indicate that the dust adhesion force depends on the grain velocity during conveying.
Yet, no aspiration event was detected with either a supraglottic airway or endotracheal intubation. Airway management and pulmonary aspiration during surgical interventions in pregnant women in the 2nd/3rd trimester and immediate postpartum - a retrospective study in a tertiary care university hospital

The results indicated that the manner in which a powder is handled may be as important as material dustiness as measured by a dustiness tester in reducing aerosol generation. To identify the dust generation processes, aluminum oxide powder was dropped as a free falling slug in a test chamber. The effect of the slug's mass, diameter, …
Some particularities of dust modelling in reactor-relevant conditions are analyzed with an emphasis on dust generation mechanisms relevant for disruption scenarios and on dust remobilization mechanisms relevant for ramp-up scenarios.
Although the significance of studying the dust generation characteristics of different coal types has been widely recognized, the dust generation process during on-site coal production can hardly be truly replicated in the laboratory due to the particularities of cutting equipment, production technology, and on-site environment.

Larger endotracheal tube size was associated with increased risk of aspiration and laryngeal granulation tissue. Using smaller endotracheal tubes may reduce the risk of postextubation aspiration.
During the planning and prioritization phase of the analysis stage, you should have set some measurable goals and key performance indicators. Once you've implemented your content localization strategy and the dust has settled a little, it's time to look at those goals and see how you did.
