Aerosols and Aerosol Propellants in Asthma

JAMA: The Journal of the American Medical Association, 1971
To the Editor.— In my practice of diseases of the chest, I have at least 1,000 patients who use and rely on a pressured aerosol device containing isoproterenol. Depending on the extent of their respiratory embarrassment, they use this device from 1 to 20 times a day.

Clinical aerosols II. Therapeutic aerosols

Archives of Internal Medicine, 1982
The current uses of clinical aerosols such as water, saline, mucolytics, bronchodilators, cromolyn sodium, corticosteroids, and antimicrobials have been reviewed. The benefits of water, saline, and detergent aerosols continue to be surrounded by uncertainty and controversy.

Atmospheric aerosols: composition, transformation, climate and health effects.

Angewandte Chemie, 2005
Aerosols are of central importance for atmospheric chemistry and physics, the biosphere, climate, and public health. The airborne solid and liquid particles in the nanometer to micrometer size range influence the energy balance of the Earth, the ...

Aerosols and Climate

Science, 1974
To determine the effects of atmospheric aerosols on the radiative heating of the earth-atmosphere system, the radiative transfer equation is solved analytically in the two-stream approximation. It is found that the sign of the heating is independent of optical thickness of an aerosol layer and the amount of heating approaches a finite limit with ...

Aerosols and devices

Respiratory Care Clinics of North America, 2001
The success of aerosol therapy depends upon the delivery of ample amounts of the drug to appropriate sites in the lung with minimal side effects. Successful aerosol therapy delivery systems must provide sufficient respirable particles or droplets, with minimal loss of the drug. Ultimately, the patient must be able to use the device easily, maintain it,

O/C and OM/OC ratios of primary, secondary, and ambient organic aerosols with high-resolution time-of-flight aerosol mass spectrometry.

Environmental Science and Technology, 2008
A recently developed method to rapidly quantify the elemental composition of bulk organic aerosols (OA) using a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is improved and applied to ambient measurements. Atomic oxygen-to-carbon

Aerosol sampler for analysis of fine and ultrafine aerosols

Analytica Chimica Acta, 2018
A new aerosol sampler based on the original version of Aerosol Counterflow Two-Jets Unit (ACTJU) is described. The ACTJU collector, connected with a water-based Condensation Growth Unit (CGU) placed upstream of the ACTJU, accomplished the quantitative collection of fine and ultrafine aerosol particles down to a few nanometers in diameter.
