Arterial Pressure Waveform Analysis on Cardiac Output Monitoring

Part of the Lessons from the ICU book series (LEICU)


Among the current methods available for cardiac output monitoring, arterial pressure waveform analysis (APWA) is one of the most widely used. This technique allows the continuous estimation of cardiac output under the premise that there is a predictable relationship between arterial pressure and stroke volume. However, as the arterial pressure is the result of interaction between ventricular ejection and the arterial system, how the arterial system is characterized will ultimately define the characteristics and limitations of each APWA algorithm.

This chapter will describe the physiological assumptions of the APWA to understand the benefits and limitations of this technology, in order to use it appropriately to improve patient care.
