title: [Nebulization: principles and generating process].
abstract: After a brief historical background, principles of nebulization are reviewed, i.e., factors at the origin of particle sedimentation, the procedure advantages and the importance of the particle size. Inhaled particles reach alveolar bronchioli via three mechanisms: impaction, sedimentation and diffusion. There are two different types of nebulizers: pneumatic and ultrasonic. To optimize its benefits nebulization should consist of a slow and deep inspiration followed by a pause in order to improve particle sedimentation. Nebulization should always be associated with kinesitherapy.
