Cardiac arrest, as a result of ventricular fibrillation or pulseless ventricular tachycardia, is a common phenomenon, and the only treatment available is defibrillation. Currently, defibrillators deliver either a monophasic or biphasic shock, depending on the device used. ⋯ These guidelines created a platform to address misconceptions that exist in the practice setting with regard to the use of biphasic defibrillators. The purpose of this literature review was to highlight the issues related to the practical use of biphasic energy, including optimal energy selection and safety.

Promoting adherence to self-care illness management strategies among patients with heart failure (HF) has been associated with a number of positive health outcomes. Yet, little is known about health outcomes related to self-care in the "sickest of the sick"-those patients with advanced HF who are approaching the end of life. ⋯ For example, what is meant by self-care illness management in patients who are symptomatic with exertion may differ from that of patients who are predominantly symptomatic at rest. Our challenge is to develop the simplest, least burdensome self-care illness management interventions that target the most meaningful outcomes for patients, their families, and the healthcare system.

Heart failure (HF) is a complex and costly disease process associated with high morbidity and mortality. Implanted cardiac rhythm management devices are increasingly used in the HF population to provide therapies such as protection from sudden death and cardiac resynchronization therapy. ⋯ This article will review the evidence for using diagnostic information from cardiac rhythm management devices in the management of HF patients. Future advanced monitoring devices will also be discussed.

Since 1970, pulmonary artery catheters (PACs) have been used in clinical practice to monitor the hemodynamic status of critically ill and injured patients. This technology was introduced and commercialized without considerable testing to determine safety and efficacy. ⋯ This article reviews the historical context of PAC use, findings from recent clinical trials intended to determine safety and efficacy, issues with reliability and validity of PAC use, and complications associated with PAC use. Data from recent clinical trials do not support routine use of PACs, and the authors suggest that PAC-guided therapy should be the focus of study in future trials.
