LiDCO Group Plc 24 March 2005 For immediate release 24 March 2005 LiDCO GROUP PLC ("LiDCO" or "the Company") LAUNCH OF SOFTWARE UPGRADE LiDCO Group plc, (AIM: LID) the UK-based cardiovascular monitoring company, is pleased to announce today that it has launched its new upgraded proprietary software for the LiDCOplus monitor at the 25th International Symposium on Intensive Care and Emergency Medicine in Brussels. As announced in May 2004, a contract was signed with Philips Medical Systems ("Philips") to create a communications link between LiDCO's proprietary stand-alone monitoring system and the Philips' patient monitor. This has now been completed and incorporated into the new LiDCOplus monitor. The VueLink communications link allows Philips customers' access to the minimally invasive hemodynamic data provided by the LiDCO system. The provision of such critical care parameters and hemodynamic data allow the complete picture of the patient's condition and history to be displayed and accessed throughout the hospital. As well as the Philips VueLink protocol, LiDCO also provide a real-time Ethernet based communication feature capable of delivering beat-to-beat data using a TCP/ IP protocol for hospitals without Philips monitors. LiDCO monitors are now able to be interfaced with all hospital information systems through both proprietary and inexpensive non-proprietary protocols. These communication methods offer the potential for data to be uploaded automatically to hospital information systems, without introducing key stroke or other human errors. Commenting on the launch, Dr Terry O'Brien, LiDCO's CEO, said; "We are very pleased to be able to announce these further capabilities to our PC platform monitor. This software has been designed to enable all hospitals to implement and audit the Early Goal Directed Therapy (EGDT) protocol that we announced earlier this week. In a study at St Georges Hospital London this care protocol has been demonstrated to save more than 10 bed days per patient and the reduction in complications such as infections."

It can be used in conscious or unconscious patients, and is designed to be quick and easy to set up. The monitor can be used by both doctors and nurses to measure and display beat to beat trends in blood flow and oxygen delivery to the body. Using this technology the maintenance of a target oxygenation level and/or the 'early' and rapid pay back of any oxygen debt incurred during surgery can be both achieved and, importantly, documented. The LiDCOplus monitor screen software has been specifically designed to be highly visible at a distance for routine monitoring once the patient is stabilized, whilst also providing more detailed feedback when the clinician or nurse is administering the intravenous fluids and powerful drugs that are used to increase blood flow and oxygen delivery. Summary of the advantages of the LiDCOplus technology in the treatment of high risk surgery patients: • No additional staff are needed to set and achieve oxygen delivery targets • The technology can be used by a nurse and does not require a specialist clinician • It can be set up quickly and easily • The monitor is specially designed to be make precise critical measurements easy to read and interpret, enabling swift corrective action to be taken when needed • The technology enables an audit trail of medical data to be recorded and passed to the hospital's patient information system • Significantly less invasive with commensurately lower infection rate reduced risk of tissue damage and less trauma for the patient than with older catheter based technologies • Collectively, these factors mean better clinical outcomes for patients, lower demands on critical care units staff, and lower costs overall for the healthcare provider. TCP/IP (Transmission Control Protocol/Internet Protocol) TCP/IP is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). General Notes about LiDCO Plc LiDCO is a UK based AIM traded developer, manufacturer and leading supplier of minimally invasive, computer-based hemodynamic monitoring equipment and disposables used primarily for the management of critical care and cardiovascular risk hospital patients. The technology was invented in the Department of Applied Physiology based at St Thomas' Hospital, London where the Company maintains a research base. The Company's manufacturing facility is in Hoxton, London and its current products are: • LiDCOplus and PulseCO monitors: computer-based platforms for displaying a range of real-time, continuous hemodynamic parameters including cardiac output, oxygen delivery and fluid volume; • LiDCO disposables: accurately determine cardiac output in a minimally-invasive manner. The Company has achieved registration of its products in 13 markets in Europe, the USA and Japan. It sells direct to the NHS in the UK, and through a worldwide network of specialty critical care distributors.
