The environment is filled with wonderful examples of medical technology that provide emergency life support, improve well-being, and offer the possibility of a longer and more productive life. But these devices are no longer only a part of the external environment. As technology advances, more devices are becoming a part of the internal environment (i.e., our bodies) as well. For some people an implanted mechanical device, such as a cardiac pacemaker or a cardioverter defibrillator, is readily accepted; for others it may be seen as an encroachment. It may be a symbol of loss and debilitation or of independence and resilience. What makes the difference? How can nurses facilitate a healthy adjustment and healing in an era permeated with technology? A discussion of the symbolism, related theory, and nursing implications is provided.
