The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.

The Atomic Theory of Matter

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers thought about atoms and “elements” as...

Detecting Reactive Oxygen Species

Reactive oxygen species are chemically active, oxygen-derived molecules capable of oxidizing other molecules. Because of their reactive nature, there are many deleterious effects associated with unchecked ROS production, including structural damage to DNA and other biological molecules. However, ROS can also be mediators of physiological signaling. There is accumulating evidence that ROS play significant roles in everything from activation of transcription factors to the mediation of...

Atomic Mass

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which are...
FAQs
An oxygen stream transfers momentum to the liquid surface as it passes through or across the formulation. The resulting shear disturbs the surface and breaks the liquid into droplets that remain suspended as an aerosol. This mechanism links gas motion to droplet formation, so changes in flow conditions can alter the spray produced for respiratory delivery.
Two source-supported variables are oxygen flow conditions and liquid properties. Flow determines how the moving gas interacts with the liquid, while the formulation itself affects how readily its surface breaks into droplets. Considering both variables is important when evaluating spray consistency, suspended-droplet formation, and the efficiency with which an aerosol can reach the intended airway location.
Suspension keeps the atomized liquid available as an aerosol rather than immediately remaining as a bulk liquid. In medical contexts, that state supports nebulization and aerosolized medication delivery, while also allowing researchers to examine how effectively a formulation is transported toward the airways. The outcome depends on the interaction between aerosol formation and delivery design.
A supported workflow begins with a liquid formulation and an oxygen stream directed through or across it. The resulting spray can then be considered in terms of aerosol formation, suspended droplets, and delivery efficiency. Researchers may vary flow conditions or liquid properties to compare outcomes and inform the design of oxygen-powered medical devices.
Design must account for the oxygen stream, the liquid formulation, and the region where the gas contacts the liquid. It must also support movement of the resulting aerosol toward the intended airway application. These elements connect atomization behavior with delivery efficiency, making device design inseparable from the flow conditions and formulation properties that shape the spray.
It is relevant when a medical system must turn a liquid formulation into an airway-directed aerosol. Supported uses include nebulization, aerosolized medication delivery, and controlled application of liquid formulations to the airways. In each case, oxygen flow atomization provides a basis for examining whether the spray forms appropriately and how efficiently the resulting aerosol is delivered.
