- Registration Number
- NCT04685733
- Lead Sponsor
- CareTaker Medical LLC
- Brief Summary
- Comparison studies comparing hemodynamic parameters provided by the Caretaker against respective Gold Standard references. 
- Detailed Description
- 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.
