Article Abstract

The human body is a process that when monitored with medical instrumentation produces one or more data streams. Current medical practice is to use the raw data for decision making. Most medical devices display the data, a few devices display graphs of the raw data.

Our work demonstrates that human body data streams may be analyzed and displayed as Shewhart process control charts (averages and standard deviations). Industry recognizes the advantages of using Shewhart process control charts to monitor and control many different processes. Although the medical industry uses control charts in the operations of hospitals, until now, this tool has not been applied to the practice of medicine.
