O5. Inhaler technique

Inhaler devices must be explained and demonstrated for patients to achieve optimal benefit. It is necessary to check regularly that the patient has the correct inhaler technique. Elderly and frail patients, especially those with cognitive deficits, may have difficulty with some devices. The cost of inhaler devices varies between products. As there are no differences in patient outcomes for the different devices, the cheapest device the patient can use adequately should be prescribed as first line treatment. (NHS Centre for Reviews and Dissemination, 2003) The range of devices currently available, the products and dosage, as well as their advantages or disadvantages, are listed in Appendix 2.
