Pressurized aerosols in asthma.

Aerosols generated by accidents: pressurized liquid release experiments.

Safety assessments and environmental impact statements for facilities require an estimation of airborne releases from accidents. Aerosols generated by accidents are being investigated to develop the source terms for these releases. One example of a severe accidental release event is a pressurized liquid release. Pressurized liquid release experiments performed in static air measured the mass ai...

"Metered dose pressurized aerosols and the ozone layer".

The term "aerosol" has a precise scientific definition as liquid or solid particles suspended in air [1], but has in the last few decades acquired a new non-scientific meaning as a self-contained, sprayable product in which the propellant force is supplied by liquefied gas [2]. The propellants used in these aerosol canisters are of several types, namely: a) chlorofluorocarbons (CFCs); b) hydroc...

Orciprenaline, and Salbutamol Aerosols in Asthma

Milner, A. D., and Ingram, D. (1971). Archives of Diseases in Childhood, 46, 502. Bronchodilator and cardiac effects of isoprenaline, orciprenaline, and salbutamol aerosols in asthma. The bronchodilator and cardiac effects of 0-5% isoprenaline, 2 5% orciprenaline, and 0-5% salbutamol, and a placebo solution inhaled as a nebulized mist from a Wright nebulizer were compared with the help of 12 as...

Dosing efficiency and particle-size characteristics of pressurized metered-dose inhaler aerosols in narrow catheters.

An experimental in vitro model was used to determine the effects of intraluminal catheter diameter and length on the delivered dose and particle-size characteristics of salbutamol (albuterol) aerosol delivered by metered dose inhaler (MDI) (Ventolin, 100 micrograms per puff). The dose of aerosolized drug that exited a 16-cm-long tracheal tube with an inner diameter (ID) of 6 mm was compared wit...
