Mining Intensive Care Vitals for Leading Indicators of Adverse Health Events
Content Type: Abstract
The status of each Intensive Care Unit (ICU) patient is routinely monitored and a number of vital signs are recorded at sub-second frequencies which results in large amounts of data. We propose an approach to transform this stream of raw vital… read more… We apply principal component analysis to this, and the top p components are considered further. These p components … the task, we perform an exhaustive search across all pairs of CuSum event types (inputs) and alert types … purpose) Fig. 1. Increased frequency of CuSum events (top) typically precedes the real apnea alerts (bottom). … -
Real-time Adaptive Monitoring of Vital Signs for Clinical Alarm Preemption
Content Type: Abstract
Cardiovascular event prediction has long been of interest in the practice of intensive care. It has been approached using signal-processing of vital signs [1-4], including the use of graphical models [3,4]. Our approach is novel in making data… read more… predict acute hypotension.
