Factors influencing nebulizing efficiency

摘要: In recent years, the use of nebulisers to generate aerosols has been greatly extended because their numerous advantages. Two types are commonly used, each based on a different principle : - jet nebulisers, Venturi effect fragment liquid preparations into small droplets. ultrasonic using vibrations quartz produce aerosol. The lacks standardisation, which may account for certain inefficiency. First all, we defined parameters required evaluate nebulisation efficiency. Although droplet size is used parameter, it not sufficient forecast It must be associated with quantity drug nebulised and time. Secondly, listed factors influencing
