The Medical Products Group of the Hewlett-Packard Company has enhanced its flagship patient monitoring system, the HP Viridia CMS 2000 series, with new measurements and optimized connectivity, flexibility, and integration with a variety of patient bedside devices. As a result, the novel Viridia Component Monitoring System 2000 family includes a wide range of advanced monitoring capabilities and features models designed specifically for adult, neonatal and paediatric patients, as well as for the anaesthesia environment. The latest functions can be incorporated into any CMS patient monitor via software and hardware updates.
The HP Viridia CMS 2000 series features the innovative EASI 12-lead electrocardiogram (ECG) technology licensed from Zymed Inc. and that right now is pending Food and Drug Administration (FDA) clearance. Unlike conventional 12-lead ECG solutions, which require ten electrodes, the EASI system uses only five electrodes and three vectors to supply a continuous 12-lead ECG at the bedside. The use of fewer electrodes and cables turns the EASI system into a more convenient diagnostic tool for nurses as well as a more comfortable one for patients. Clinicians are now able to treat patients without being encumbered by electrodes and cables.
The HP company has also incorporated a new electro-encephalogram (EEG) monitoring capability for adult, paediatric and neonatal patients, which is currently not available in the United States. EEG monitoring, that measures the electrical activity of the brain, is applied in operating rooms and critical-care environments to track subtle changes in cerebral function. The HP tool produces two channels of EEG real time waves with Compressed Spectral Array (CSA) and calculates eight numerics. In addition, a high-performance pulse-oximetry (SpO≤) algorithm uses a sophisticated analysis technique to increase the measurement accuracy of SpO≤, reducing the number of false alarms, even in the presence of multiple artifacts. This is of great importance in environments where patients move frequently, such as post anaesthesia and neonatal departments, and for patients who suffer from poor perfusion.
Thus, the new HP Viridia CMS 2000 series offers comprehensive information management across the acute-care continuum. The system provides local data integration, bed-to-bed and unit-to-unit overviews, and data integration with central monitoring and clinical information management systems. The HP VueLink module includes a library of interfaces to devices, developed by other manufacturers, such as ventilators, anaesthesia machines, incubators and stand-alone measurement devices. Clinicians can connect any standard XGA-compatible display to the HP Viridia CMS 2000 series patient monitors, including HP's proprietary medically approved super-flat screen. The user interface is designed to optimize ease of use and facilitate training.
It is possible to upgrade every HP CMS unit in the field to the same level of performance as the new systems which are currently brought to the market. According to Hans-Guenter Hohmann, who is general manager of the Patient Monitoring Division, updating rather than replacing the existing equipment constitutes a significant cost saving for the hospitals.
