The EDM and EDM+ are designed to allow clinicians to guide fluid and drug administration during critical care. The monitors are highly responsive in tracking changes in Stroke Volume and Cardiac Output during intervention.
Only esophageal Doppler has been shown to have the precision to drive the 10% Stroke Volume Optimization algorithm widely acknowledged as the basis for Fluid Management.
Additionally the EDM+ has a Pulse Pressure Waveform (PPWA) mode which is quickly and easily calibrated from the Doppler signal, providing continuous monitoring for postoperative and medical patients in Critical Care. In sedated patients the PPWA algorithm can be recalibrated at any time from the Doppler waveform.
Treatment algorithm suggested by Professor Mervyn Singer, University Hospital, London.
Evidence & Benefits
The majority of evidence supporting fluid management comes from the surgical setting. For a summary of that evidence, see our Evidence Table.
EDM has been demonstrated to improve patient patient outcome when used to manage fluid administration and cardiovascular function in postoperative, and medical Critical Care patients. View the Library for a list of references.
The addition of Pulse Pressure Waveform Analysis (PPWA) into EDM+ allows continuous hemodynamic monitoring and provides additional utility over EDM in the Critical Care setting.
