DEMONSTRATION OF NEW REMOTE HEMODYNAMIC MONITORING PRODUCT - LIDCOLIVE

LiDCO, the UK based, AIM-quoted cardiovascular monitoring company, today
announces the successful demonstration of its new remote monitoring software
product LiDCOlive.

Background to the LiDCOlive market requirement.

The number of monitored beds in hospitals is steadily increasing and now
represents 10% of all in-patient beds and approximately 30% of a hospital's
revenues. Hemodynamic monitoring guided fluid and drug therapy enables the
maintenance of key physiological parameters such cardiac output and oxygen
delivery, thereby significantly reducing complications and costs associated
with treatment of high-risk patients. The growing shortage of the highly
skilled intensive care staff necessary to care for these patients has created a
requirement for a monitoring technology that not only provides real time
hemodynamic data but also allows the more efficient use of existing clinical
staff's expertise.

The LiDCOlive Product - towards the `virtual ICU'.

One way of achieving this is to take both the patient data and monitor display
to the clinician irrespective of physical location. LiDCO has therefore
developed a software product called LiDCOlive that can display the LiDCOplus
Monitor trend screen and real time patient data on any PC or laptop anywhere -
in or out of the hospital. The requirement is that the customer has a LiDCOplus
Monitor at the patient's bedside that is connected to the hospital network and
then on to the internet. The clinician can then log on externally to the
hospital's server with a standard PC and see exactly the same data and screen
display as the nurse at the bedside. The clinician and nurse can then discuss
potential treatment approaches and both immediately and simultaneously see the
effects of their agreed change in fluid or drug therapy. This `virtual ICU'
approach using LiDCO's technology has the potential to considerably improve the
care of high-risk patients and make savings to hospitals budgets. The LiDCOlive
was demonstrated both in Japan (Kobe) during the Japanese Intensive Care
Society meeting and in a critical care meeting in Brno, Czech Republic during
the first week of March. At both meetings patients were monitored remotely,
with live patient data being sent via the internet from the University Hospital
in Olomouc, Moravia and Frimley Park Hospital, Surrey, UK.

Dr. Loua Shaikh of the Department of Critical Care Medicine, Frimley Park
Hospital, UK said:

"We are delighted to be the first hospital to implement the LiDCOlive remote
patient viewing software. In the critical care environment the ability to
remotely monitor a patient's hemodynamic data represents a significant step
forward. With remote access to LiDCO's advanced minimally invasive monitoring
technology we are able to assist colleagues at the bedside to make the best
treatment decisions for our patients. Clearly the ability to see LiDCO's
advanced user interfaces from a remote PC as if one were at the bedside makes
treatment decisions much more meaningful. One now has the ability to solicit
remote expert opinion as if they were with you in the intensive care unit. In
terms of patient care the impact of time and distance on the delivery of
experience and expert knowledge, to the bedside are considerably diminished."

The technology will be demonstrated at the ISICEM in Brussels on the 27th to
30th March, with the LiDCOlive data being sent from a hospital in the Czech
Republic in combination with live video footage of the bedside. The LiDCOlive
product is scheduled for wider clinical release towards the last quarter of
2007.

About LiDCO Group 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. Use of LiDCO's technology has been shown
to significantly reduce 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.

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: used in conjunction with the LiDCOplus Monitor to
accurately determine cardiac output in a minimally-invasive manner.

* LiDCOview - software product for use on a PC: designed to aide clinical
audit, teaching and research activities.

Distribution Network:

The Company has now achieved registration of its products in 14 markets in
Europe, the USA, Brazil and Japan. It sells direct in the UK and USA, and
elsewhere through a worldwide network of specialty critical care distributors.
