Introduction
• Intensive Care Units (ICUs) treat patients that are in a critical (life-threatening) physiological state.
• More than 4.000.000 people are admitted each year in ICUs in the U.S. alone – 500.000 of them do not survive. (The Leapfrog group,
2000)
– 12%

Motivation
• Human factor (on call ICU nurse) still is the invaluable tool in the ICU setting.
• Clinical systems commercially available utilize proprietary code and interface protocols.
• High cost to purchase, deploy and manage commercially systems.

Challenges
• A plethora of medical devices are used in the ICU to monitor the patients.
• The vast majority of medical device vendors utilize proprietary communication interfaces and languages to export information.
• Large volumes of produced data (physiological parameters, vital signs, medical images) that hospitals infrastructures cannot store for large periods of time.
• Personal and sensitive data.

Near future work
• Full scale deployment for longer period of time.– This will rise new needs and feature requests
• Initiate an open source project.
• Enhance local search functionality.
• Introduce ICU scoring functionality (Acute Physiology and Chronic Health Evaluation , Simplified Acute Physiology Score, …).
• Extend the medical device driver library.
