DECISION TREE FOR SELECTING A SUITABLE INHALATION SYSTEM

The choice of inhalation system depends on patient-specific factors, the properties of the inhalation system, and the medication with which it is to be used.

For patients who are unable to inhale in a controlled, coordinated manner, metered dose inhalers (MDI) that use a propellant gas should only be used together with a spacer or a holding chamber as far as possible. If the patient is not capable of creating an adequate inspiratory flow, most dry powder inhalers (DPIs) are unsuitable. In these cases, nebuliser systems represent a good alternative.
