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.

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 ReportsRecognizing and treating ischemic insults to the brain: the role of brain tissue oxygen monitoring.
This article describes the potential application of brain tissue oxygen monitoring technology in the care of patients who have sustained traumatic brain injury (TBI) or subarachnoid hemorrhage (SAH). To accomplish this objective, a review of the intracranial dynamics that are created by primary and secondary brain injury, and the challenges of optimizing oxygen delivery to the injured brain are presented. Furthermore, interventions that facilitate cerebral oxygen supply and reduce oxygen consumption are identified. Finally, application of this technology is highlighted by using case vignettes of patients who have TBI or SAH.
