Although studies do not report measurement error as a result of this phenomenon, this must be an inherent risk in any form of pulse contour analysis. Clinical application The equipment provides a valuable guide to fluid and inotropic therapy livco high-risk patients in the intensive care unit, operating theatre and other critical care areas. There then follows a review by Dr Rupert Pearce, who has experience with the technology but no competing interests. In a recent study utilizing the LiDCOplus it was shown that Components of the LiDCOplus Monitor The PulseCO software calculates continuous beat-to-beat cardiac output by analysis of the arterial blood pressure trace following calibration with an absolute cardiac output value.

Equipment review: An appraisal of the LiDCO™plus method of measuring cardiac output

Performance may be compromised in patients with severe peripheral arterial vasoconstriction, in those undergoing treatment with aortic balloon pumps and in those with aortic valve regurgitation. Surgery patients that are unable to balance oxygen delivery and consumption develop a peri-operative oxygen debt that increases the risk of surgical complications and death.

Intraoperative intravascular volume optimisation and length of hospital stay after repair of proximal femoral fracture: National Center for Biotechnology InformationU. Thus, in patients with conventional indications for invasive arterial blood pressure monitoring, the device is intended as a means to display continuous haemodynamic data in a comprehensive manner.


This is not problematic unless the pulse rate is particularly irregular. The pharmacokinetics of intravenous lithium chloride in patients and normal volunteers. Total procedure time was less than 3hrs and the total abdominal exposure time was 2. No additional side effects of the administration of lithium by this route have been reported.

While air bubbles or blood clots in the arterial cannula may be removed, kinking of the cannula may necessitate recalibration or even replacement of the arterial cannula followed by recalibration.

Critical Care vol Training in the use of the system is necessary, but with practice it is possible to perform an initial calibration within 10 min and subsequent recalibrations within 5 min. The Online Medical Device Exhibition. Prediction of fluid responsiveness One indication for the use of flow monitoring is the prediction of fluid responsiveness. Open the catalog to page 7. This screen simplifies the recognition and diagnosis of hemodynamic imbalance at the bedside.

These articles should be read in conjunction as they are designed to assess the technology from two different perspectives. The system has been used successfully with arterial cannulae in various sites, although not all have been scientifically validated.

Lithium indicator dilution Several studies have evaluated the lithium dilution technique of cardiac output measurement, most frequently in comparison with thermodilution using the PAC. The effectiveness of right heart catheterisation in the initial care of the critically ill patients.

Goal Directed Therapy

Catheter induced pulmonary artery hemorrhage. Clinical use of respiratory changes in arterial pulse pressure to monitor the hemodynamic effects of PEEP. A peripheral venous cannula may be used although a central venous catheter is preferable. Arterial waveform artefact may significantly affect data accuracy. The equipment provides a valuable guide to fluid and inotropic therapy in high-risk patients in the intensive care unit, operating theatre and other critical care areas.


An unusual case of pulmonary artery catheter malfunction.

Implications of arterial pressure variation in patients in the intensive care unit. Open the catalog to page Diagnosis and management in cardiac operations. Following the liver resection the total fluid volume given to olus normovolemia was only 1.

Radiology of the Swan-Ganz catheter and associated pulmonary complications. Systolic pressure variation predicts the response to acute blood loss [abstract] J Clin Anesth. Meta-analysis of hemodynamic optimisation in high-risk patients. The LiDCOplus monitor displays the parameter of oxygen delivery and oxygen delivery index in real time. Positive end-expiratory pressure-induced hemodynamic changes are reflected in the arterial pressure waveform [abstract] Crit Care Med.

Strengths Weaknesses May be used in conscious and unconscious patients Arterial waveform artefact may significantly affect data accuracy May be calibrated by nursing or medical staff in 10 min Irregular pulse rate may affect data accuracy Provides dynamic markers of fluid responsiveness Nondepolarizing muscle relaxants interfere with calibration.

These include the following: A comprehensive approach to improved outcome in moderate to major risk surgery patients should be capable of allowing hemodynamic optimization across the whole peri-operative period. Open the catalog to page 5. Perioperative plasma volume expansion reduces the incidence of gut mucosal hypoperfusion during cardiac surgery.

This concern applies to all cardiac output measurement techniques. Goal-directed therapy in high risk surgical patients Critical Care Lees, Hamilton and Rhodes, ; Hamilton et al.
