Abstract

Over the last several decades, multiple studies have identified improper asthma rescue inhaler technique as a clinically important correlate of unstable disease and increased use of healthcare services. It is believed that inconsistencies in what is described as “proper” technique by various sources may contribute to patient confusion and poor outcomes in clinical practice. It is important to review pressurized metered-dose inhaler (pMDI) protocols as defined by the literature and manufacturers, as well as to understand how the technique employed in each step affects the delivered dose. Presumably, knowledge of this information will clarify aspects of pMDI usage that are potentially confusing, as well as inform patient education and the development of effective asthma action plans.
