Telemedicine was recognized in the 1970s as a legitimate entity for applying the use of modern information and communications technologies to the delivery of health services. Telecardiology is one of the fastest growing fields in telemedicine. ⋯ This article discusses current advancements, the scope of telemedicine in cardiology, and its application to the critically ill. The impact of telecardiology consultation continues to evolve and includes many promising applications with potential positive implications for admission rates, morbidity, and mortality.

ReviewIncreasing Quality Through Telemedicine in the Intensive Care Unit.
This article explores the hypothesis that a telemedicine intensive care unit (Tele-ICU) platform is uniquely suited to facilitate quality performance improvement (PI). This article addresses some substantial hurdles to overcome that may limit the effectiveness of a Tele-ICU platform to achieve PI objectives. Lastly, this article describes the author's experience with a PI project to improve ventilator management conducted via a Tele-ICU hub interacting with 11 geographically dispersed ICUs. Using this example to illustrate the concepts, the author hopes to shed some light on the successes and lessons learned so as to generate best-practice guidelines for Tele-ICU-directed PI initiatives.

ReviewThe Interface Between Monitoring and Physiology at the Bedside.
Hemodynamic instability as a clinical state represents either a perfusion failure with clinical manifestations of circulatory shock or heart failure or 1 or more out-of-threshold hemodynamic monitoring values, which may not necessarily be pathologic. Different types of causes of circulatory shock require different types of treatment modalities, making these distinctions important. Diagnostic approaches or therapies based on data derived from hemodynamic monitoring assume that specific patterns of derangements reflect specific disease processes, which respond to appropriate interventions. Hemodynamic monitoring at the bedside improves patient outcomes when used to make treatment decisions at the right time for patients experiencing hemodynamic instability.

Although use of the classic pulmonary artery catheter has declined, several techniques have emerged to estimate cardiac output. Arterial pressure waveform analysis computes cardiac output from the arterial pressure curve. ⋯ Some newer devices have been developed to estimate cardiac output from an arterial curve obtained noninvasively with photoplethysmography, allowing a noninvasive beat-by-beat estimation of cardiac output. This article describes the different devices that perform pressure waveform analysis.
