BACKGROUND Intensive care unit telemedicine is an innovative approach to providing critical care services for a broad geographic area, but its success may depend on acceptance by bedside providers. OBJECTIVES To determine critical care nurses' attitudes toward and perceptions about the use of telemedicine in critical care. METHODS A total of 179 nurses(More)
BACKGROUND Early extubation in select cardiac surgery patients reduces tracheal intubation times, intensive care unit length of stay, and hospital length of stay. While there is good evidence in the literature to support early extubation, there is very little published research that describes how to study and redesign processes of care to increase early(More)
We conducted a retrospective, observational study of patient outcomes in two intensive care units in the same hospital. The surgical ICU (SICU) implemented telemedicine and electronic medical records, while the medical ICU (MICU) did not. Medical charts were reviewed for a one-year period before telemedicine and a one-year period afterwards. In the SICU,(More)
The paper presents a fingertip photoplethysmography based technique to assess patient fluid status that is robust to waveform artifacts and health variability in the underlying patient population. The technique is intended for use in intensive care units, where patients are at risk for hypovolemia, and signal artifacts and inter-patient variations in health(More)
Hypovolemia caused by internal hemorrhage is a major cause of death in critical care patients. However, hypovolemia is difficult to diagnose in a timely fashion, as obvious symptoms do not manifest until patients are already nearing a critical state of shock. Novel non-invasive methods for detecting hypovolemia in the literature utilize the(More)
In this work, we describe the state of clinical monitoring in the intensive care unit and operating room, where patients are at their most fragile and thus monitoring is most heightened. We describe how large amounts of data generated by monitoring patients’ physiologic signals, along with the ubiquitous aspecific threshold alarms in use today, cause(More)
