Pulse oximetry is a non-invasive measurement method of an arterial blood oxygen saturation. Pulse oximeter is one of the main bedside monitors used in neonatal units. The dispersed location of medical devices in such unit renders impossible to make a fast and valid decision in the case of simultaneous alarming situation. This paper present hardware and software structure of centralised neonatal monitoring system. Presented system can work as a single central station for monitoring of up to twenty four patients. Application of central monitoring system decreases the risk of undetected patients live and health threats. Thanks to this system the medical stuff is less burdened by routine procedures; therefore the medical unit is perceived as child- and mother-friendly.

Monitoring vital signals is one of the most important tasks performed by the medical equipment nowadays. One of the most frequently applied monitoring types is the pulse oximetry, based on monitoring of arterial oxygen saturation. The design presented in this paper is a modular construction. One of the most important improvements is the application of the embedded PC module in the design of a pulse oximeter. The modular PC is using open source software. The system presented in this paper uses digital detector technology and the input pulse oximeter module developed by the Dolphin Medical. One of the main aims of the research team was to create a design capable of monitoring both vital signals of adults and newborns, to make the device suitable for pediatric and neonatologic wards. Performed tests and examinations for system stability as well as the comparision with other similar devices available on the market confirmed that the presented device design is an optimal solution for the described class of devices. By using the PC module the scalability of the system seriously increases comparing to other designs. The separation of the data acquisition part of the device and the analytical part of the device in the form of a personal computer module makes the device more alike medical computer system than the traditional pulse oximeter responsible only for visualiasation of the read data.
