ReviewPractice standards for ECG monitoring in hospital settings: executive summary and guide for implementation.
Current goals of hospital ECG monitoring are to diagnose cardiac arrhythmias, acute myocardial ischemia, and drug-induced prolonged QT interval. Recently, experts in the field of electrocardiology and cardiac monitoring convened to develop a practice standard for hospital ECG monitoring. This executive summary reviews key elements of the practice standard and answers questions that often arise when clinicians try to implement them.

Review Case ReportsContinuous ST-segment monitoring: raising the bar.
ST-segment monitoring is recommended by clinical experts to assist in the early detection of transient myocardial ischemia; however, a gap exists between the recommendations and clinical practice. This article provides a review of research to support the use of ST-segment monitoring in a variety of clinical situations. Patient selection for monitoring, techniques, and strategies to facilitate successful implementation of ST monitoring are included. Nurses are encouraged to advocate for patients by raising the bar of electrocardiogram monitoring practice to aid in optimizing patient outcomes.

Review Case ReportsEsophageal Doppler monitoring for hemodynamic assessment.
This article reviews the importance of hemodynamic monitoring in adding to the clinical assessment of critically ill patients. The esophageal Doppler monitor (EDM) provides a less invasive way of obtaining hemodynamic information quickly and safely at the bedside. The concepts of Doppler signal acquisition and important nursing considerations are reviewed. Case studies are provided to understand how data from the EDM can impact patient care decisions at the bedside.

ReviewEnd-tidal carbon dioxide monitoring: a VITAL sign worth watching.
Capnography is the monitoring of end-tidal carbon dioxide in waveform and numeric display. For this technology to be useful, the critical care nurse must have a clear understanding of the normal capnography waveform and what the alterations in this waveform represent. The critical care nurse can use this information to plan patient care interventions with other critical care team members and to adjust care based on the patient's response. End-tidal carbon dioxide physiology, normal waveforms, abnormal waveforms, and clinical aspects of capnography monitoring are included.

ReviewArterial pressure-based technologies: a new trend in cardiac output monitoring.
New trends in cardiovascular monitoring use the arterial pulse as a less invasive means of assessing cardiac output. When adopting a new technology into practice, three questions need to be answered: (1) is the method technologically sound?, (2) is it based on physiologic principles?, and (3) are the applications clinically important? This article provides a clinical review on the technology, physiology, and applications of a new arterial pressure-based method of determining cardiac output and stroke volume variation as an additional parameter for fluid status assessment.
