From the infant to the geriatric patient-Strategies for inhalation therapy in asthma and chronic obstructive pulmonary disease.

Abstract

Inhalation therapy represents the standard of care in children, adolescents as well as in young, middle-aged and geriatric adults with asthma or chronic obstructive pulmonary disease. However, there are only few recommendations for the choice of inhalation devices, which consider both, age-specific limitations in young and geriatric patients. Transition concepts are lacking. In this narrative review, the available device technologies and the evidence for age-specific problems are discussed. Pressurized metered-dose inhalers may be favoured in patients who fulfill all cognitive, coordinative and manual power requirements. Breath-actuated metered-dose inhalers, soft-mist inhalers or the use of add-on devices such as spacers, face masks and valved holding chambers may be suitable for patients with mild to moderate impairments of these variables. In these cases, available resources of personal assistance by educated family members or caregivers should be used to allow metered-dose inhaler therapy. Dry powder inhalers may be reserved for patients with a sufficient peak inspiratory flow and good cognitive and manual abilities. Nebulizers may be indicated in persons who are either unwilling or unable to use handheld inhaler devices. After initiation of a specific inhalation therapy, close monitoring is essential to reduce handling mistakes. An algorithm is developed that considers age and relevant comorbidities to support the decision-making process for the choice of an inhaler device.
