Esophageal Doppler is a reliable, noninvasive cardiac output monitor that helps guide intravascular fluid resuscitation and optimize cardiac output in high-risk surgical patients.
Esophageal Doppler is a reliable noninvasive tool for monitoring cardiac output and guiding fluid resuscitation, particularly beneficial in high-risk surgical patients.
In this article we describe the esophageal Doppler, a noninvasive, instantaneous cardiac output monitor. Its reliability has been demonstrated to be comparable to that of other current techniques used in the clinical arena to measure cardiac output. It helps guiding intravascular fluid resuscitation by quantifying the increase in flow in response to fluid challenges and by indicating the plateau of the patient's cardiac function curve. When the plateau has been reached, further fluid loading may result in congestion without improvement in systemic flow. Thus, measuring cardiac output is the only way to determine the upper limit for fluid intake. In addition, a strategy based on cardiac output optimization has proven beneficial in high-risk surgical patients.
Cholley et al. (Sat,) conducted a review in High-risk surgical patients. Esophageal Doppler was evaluated. Esophageal Doppler is a reliable, noninvasive cardiac output monitor that helps guide intravascular fluid resuscitation and optimize cardiac output in high-risk surgical patients.
