摘要Introduction Reliable bedside cardiac output monitoring has been sought in clinical practice since the 198http://aims.cuhk.edu.hk/converis/portal/Publication/0s when the technology became available to support it. A number of monitoring modalities have been developed over the last few decades that include electrical bioimpedance and reactance, arterial pressure wave analysis, continuous wave Doppler ultrasound, and “heated wire” continuous thermodilution catheters. However, the clinical evaluation of these technologies has resulted in much controversy, especially the issue of assessment of reliability. In this chapter I will review the main aspects of their assessment with special attention paid to validation and statistical methods. General considerations There are several aspects to evaluating a clinical monitor. Commonly asked questions include: Is it safe? Is it easy to use? And how much does it cost? The clinician needs a guide so that a thorough evaluation is performed. Intended use Not all cardiac output monitors are equal in what they can do and provide. Neither are the requirements of different clinical settings. In the trauma room one may require a cardiac output monitor that can rapidly tell one whether the patient is responding appropriately to fluid replacement therapy, whereas in the postoperative high dependency unit one requires a cardiac output monitor that alarms if the patient’s hemodynamic status changes suddenly. A Doppler monitor that provides reliable hemodynamic data, but is also highly operator dependent, may perform well in the trauma room setting, but when continuous surveillance of hemodynamic status on a high dependency unit is needed, continuous bioreactance or arterial pulse contour monitoring may perform better. Therefore, one needs to consider whether one’s chosen cardiac output monitor has the right characteristics to fit the monitoring requirements of the intended clinical setting.
