Abstract: The use of aerosol is a quick efficient therapy for the airway mucosa. The stability of the aerosol depends an particle concentration, size, species and surroundings humidity. For a therapeutic effect of an aerosol, penetration and sedimentation of the particle is necessary. By slow deep Inhalation followed by holding the breath for 10 seconds and a subsequent quick expiration, the best deposition is achieved. For aerosol production jet nebulizers, IPPB and ultrasonic devices are used.These devices have different indications: jet nebulizers for "everyday", IPPB for patients with diminished retraction forces of the lung and ultrasonic nebulizers to achieve a high concentration of aerosol. The use of metered aerosols needs a correct coordination of Inhalation and "firing" of the aerosol. The use of spacers with metered aerosols is promoted to overcome coordination difficulties in young and elderly people and to reduce evaporation coldness. The overall spacer Aerochamber is particularly useful as every metered aerosol fits an it. For siblings and younger children, this Aerochamber is even available with a face mask occluding the nose.Powder inhalations do not need a propellant but they have the disadvantage to require higher inhalation flows, which might be a problem in severe asthma.
