A home-based nurse-coached inspiratory muscle training intervention in heart failure
Date of Original Version
People with heart failure (HF) are living longer but with disabling dyspnea that erodes quality of life (QOL). Decreased strength of inspiratory muscles (IMs) may contribute to dyspnea in HF, and inspiratory muscle training (IMT) has been shown to improve the strength of IMs. The purpose of this study was to determine the effects of a 3-month nurse-coached IMT program. Bandura's Self-Efficacy Theory directed nursing interventions. This randomized controlled trial employed an experimental group (IMT) and a control group (education). Data were collected during six home visits. Outcome measures included maximal inspiratory pressure, perceived dyspnea, self-efficacy, and health-related QOL. Significant differences in PImax, dyspnea, and respiratory rate were found. Implications for further research and practice are discussed. © 2009 Elsevier Inc. All rights reserved.
