Characterization and comparison of Re-Du-Ning aerosol particles generated by different jet nebulizers

Comparison Testing of Competitive Portable Jet Nebulizers

A comparison of commercial jet nebulizers.

Seventeen commercially available jet nebulizers from 15 commercial sources were studied (Acorn-I, Acorn-II, AquaTower, AVA-NEB, Cirrhus, Dart, DeVilbiss 646, Downdraft, Fan Jet, MB-5, Misty Neb, PARI LC JET, PARI-JET, Salter 8900, Sidestream, Updraft-II, Whisper Jet). All nebulizers were filled with 2 ml of saline solution plus 0.5 ml of albuterol and powered with the same source (DeVilbiss Pul...

Physical and chemical characterization of tire-related particles: comparison of particles generated using different methodologies.

The purpose of this study was to characterize the physical and chemical properties of particles generated from the interaction of tires and road surfaces. Morphology, size distribution, and chemical composition were compared between particles generated using different methods, including on-road collection, laboratory generation under simulated driving conditions, and cryogenic breaking of tread...

Overcoming jet lag: optimizing aerosol delivery with and without jet nebulizers.

Early studies have shown that only a small fraction of the nominal nebulizer dose (1–12%) is available for delivery to the lungs in intubated children and adults.1-3 Since then, the characterization of forces governing aerosol delivery in ventilated patients has led to improvements in techniques, and the development of newer aerosol generators with the ability to deliver as much drug to ventila...

Testing Re nements by Re ning Tests

One of the potential bene ts of formal methods is that they o er the possibility of reducing the costs of testing. A speci cation acts as both the benchmark against which any implementation is tested, and also as the means by which tests are generated. There has therefore been interest in developing test generation techniques from formal speci cations, and a number of di erent methods have been...
