Method and system for standardized and platform independent medical data information persistence in telemedicine

Wireless communication between sensors monitoring patient vital signs has become more and more important in the past few years. Essential requirements to integrate sensors of different manufacturers into a clinical network are standardized communication protocols and a unique data representation of the vital signs. Both issues are realized by CEN ENV 13734/35 ldquoVital Signs Information Representationrdquo (VITAL) [1]. The standard was implemented and integrated into a generic framework with different interfaces allowing integration of extensions [2]. In order to guarantee readability of vital signs communicated with the VITAL framework in the future, standardized storing methods are indispensable. That is why a new user interface was created that allows standardized persistence of medical data information in real time. Focussing on our implementation, we evaluated three relevant file formats: the ldquoEuropean Data Formatrdquo (EDF/EDF+), the ldquoFile Exchange Formatrdquo (FEF) and SCIPHOX.
