Caretaker Hemodynamic Parameters Validation

Caretaker Hemodynamic Parameters Validation

Comparison studies comparing hemodynamic parameters provided by the Caretaker against respective Gold Standard references.

Comparison studies comparing hemodynamic parameters provided by the Caretaker against respective Gold Standard references.

Specifically, continuous beat-by-beat blood pressure readings against arterial catheter readings, continuous beat-by-beat left ventricular ejection times (LVET) against matching LVETs obtained from central catheters, cardiac output (CO) and stroke volume (SV) measures against thermo-dilution and Fick measurements, and standard HRV parameters based on Caretaker-provided inter-beat intervals (IBI) against the same HRV parameters obtained from ECG-based IBIs.
