About LiDCO Group Plc

LiDCO is a leading supplier of minimally invasive hemodynamic monitoring equipment and disposables. These are used primarily for the management of hospital patients requiring critical care or at major cardiovascular risk. LiDCO's computer-based technology significantly reduces the complications (particularly infections) and costs associated with major surgery. The technology was invented in the Department of Applied Physiology based at St Thomas' Hospital, London. LiDCO is based in the UK and its shares are traded on AIM.

The Company's manufacturing facility is in Hoxton, London and its current products are:

* LiDCOplus: a computer-based platform monitor used in the Intensive Care Unit for real-time continuous display of hemodynamic parameters including cardiac output, oxygen delivery and fluid-volume responsiveness (PPV% and SVV%)

* LiDCOrapid: LiDCO’s new cardiac output monitor designed specifically for use in the Operating Theatre for monitoring the hemodynamic effects of surgery, fluid administration and therapeutic drugs  . The monitor enables acute-care physicians to obtain accurate and immediate feedback on the patient's fluid balance and associated hemodynamic status - key measures of overall well-being during and after surgery.
Product benefits include:

• Early and rapid warning of hemodynamic change
• Clear indication of fluid status in ventilated patients
• Quantification of hemodynamic response, particularly stroke volume
• The displayed parameters helps the clinician to more effectively administer fluids - the right amount at the right time

Advanced hemodynamic care has been shown to contribute to:

• Reduced morbidity and complications
• Reduced length of stay
• Reduced overall cost of care

* LiDCO single-patient-use disposables: used in conjunction with the LiDCOplus and LiDCOrapid Monitors.

* LiDCOview: an easy-to-use graphical display of historical LiDCOplus hemodynamic data. Both clinical researchers and routine users can view beat-to-beat hemodynamic data collected with the LiDCOplus.
