A Low Cost Model for Patient Monitoring in Intensive Care Unit Using a Micro Web-server

This work presents a model for patient monitoring in Intensive Care Units (ICU), using a WWW application tool Micro WEB-Server (MWS) – an embedded computer system, in order to monitor physiological data, obtained by standard monitors, captured, made available via WEB and temporarily stored (previous 24 hours data). Monitors are connected to, also standard sensors connected to the patient. For the present model, the following data were chosen: (a) body temperature, (b) systolic blood pressure, (c) diastolic blood pressure, (d) cardiac frequency and (e) oxymetry. MWS executes a pre-processing, comparing each signal’s value, which sample frequency can be regulated by the professional responsible for the ICU, and it triggers an alarm when something is abnormal. It stores the previous 24 hours records in itself, besides storing them in a remote server for further studies. That means, MWS allows remote patient monitoring, via Internet, Intranet or mobile phone. This technology allows optimizing the monitoring cost in ICU.
