Filtration of respired gases: theoretical aspects.
The filtration of aerosols and the behavior of aerosolized particles are less intuitive and more complex than commonly indicated in the medical literature, but once the basic principles are presented, they are not difficult to understand or apply. Particles with diameters close to the most penetrating particle size are clearly the particles of greatest concern, interest, and value in considerin...
متن کاملHot Topics in Cold Gases
Since the first experimental realization of Bose-Einstein condensation in cold atomic gases in 1995 there has been a surge of activity in this field. Ingenious experiments have allowed us to probe matter close to zero temperature and reveal some of the fascinating effects quantum mechanics has bestowed on nature. It is a challenge for mathematical physicists to understand these various phenomen...
متن کاملPanel Discussion: Filtration of breathing gases during mechanical ventilation
Filtration of contaminated breathing gases is a necessary measure in mechanical ventilation. There are two types of filters available for filtration of breathing gases: mechanical filters and electrostatic filters. Filter efficiency can be established through a number of means, the most stringent being the High Efficiency Particulate Air (HEPA) test. While a variety of HEPA-grade filters are av...
متن کاملUse of the Curtis-Godson approximation in calculations of radiant heating by inhomogeneous hot gases.
Calculations of radiant heating by inhomogeneous hot gases require knowledge of spectral transmittances of inhomogeneous optical paths. Determination of these transmittances is a difficult problem that can be attacked by means of the Curtis-Godson approximation, which replaces each inhomogeneous optical path with a hypothetical homogeneous path that has the same transmittance. The authors have ...
