[The role of inhalation chambers in the treatment of asthma].
Inhalation chambers (spacers), interposed between the aerosol doser and the patient's mouth take 3 forms: lengthened tubes, large volume plastic sacs and conical chamber in the shape of a pear. Their chief advantages are: A greater proportion of the drug reaches the airways, as the deposition in the oropharynx is reduced. Co-ordination of lung and hand, a major obstacle to the correct use of aerosol-dosers, is no longer necessary.
