User Interface

One of the principle criticisms levelled at current monitoring modalities is their limitations in terms of facilitation of data interpretation. LiDCO attempts to address this by using modern computing power and software to present this data in a novel and interpretable format.

This is the raw data display for users who want the numbers, but also want to see the recent trend.

This screen facilitates intraoperative patient management allowing immediate response to hemodynamic changes with numeric values and two minute to twelve hour historical data.

The enhanced PulseCO™ monitor displays in real time the additional parameter of oxygen delivery. There is mounting evidence that monitoring oxygen delivery and cardiac output in at-risk patients can significantly reduce mortality and length of hospital stay.4 Therefore, the ability to have these two parameters monitored simultaneously on a real-time basis by PulseCO™ may have a major impact on patient care.

This means that complex data can be easily interpreted and the necessary corrective actions taken quickly.

For unstable patients or those displaying a high degree of hypovolemia, the PulseCO™ System is a reliable predictor of fluid volume status. By superimposing the Arterial Pressure Waveform Window onto the Trend, Graph, or Chart screens, an alternative and continuous measure of Systolic Pressure Variation, Pulse Pressure Variation, or Stroke Volume Variation is displayed. These have been indicated for use to aid the diagnosis of hypovolemia.1,2,3 A fluid imbalance can have an adverse effect on a patient's cardiac performance and, in turn, oxygen delivery to key organs.

Functions of the History Screen

The History Screen can be used to look back over up to 24 hours of hemodynamic data displayed as per the Trend Screen. At the touch of a button, record the patient's critical parameter, beat-to-beat onto an Excel file using the built in Zip Drive. Record every 24 hours worth of data for patient records or for clinical studies.
