From: Dynamic arterial elastance as a predictor of arterial pressure response to fluid administration: a validation study

Figure 1

An illustrative example of the arterial pressure and aortic blood flow recordings is shown. Both signals are integrated into the esophageal Doppler system for analysis: the arterial pressure waveform from the patient’s bedside monitor and the aortic blood flow from the Doppler probe. Dynamic arterial elastance was calculated as the ratio between pulse pressure variation and stroke volume variation. All variables are automatically calculated by the Doppler monitor, which combines the arterial pressure analysis with the usual aortic blood flow measurements.
