Helping patients to master correct inhaler techniques: nursing role.

The use of inhalers is widespread for asthma and conditions such as chronic obstructive pulmonary disease and yet many people have difficulties in mastering correct inhaler technique. Elderly people and children have specific problems with inhaler use and require both targeted and appropriate help in order to improve their inhaler technique and minimize waste of inhaled medication and therefore lack of therapeutic effect. Nurses need to be able to not only demonstrate correct inhaler technique themselves, but also identify what is going wrong and be knowledgeable concerning the various options available. Frequent assessment of inhaler technique needs to become a regular feature of health promotion for all patients using these devices.
