A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing to assess intra-arterial fluid volume is described. The system uses averaging of similar pulses based on prior (n−1; n minus 1) R-to-R pulse wave duration, and prior-prior (n−2; n minus 2) R-to-R pulse wave duration, to determine a patient's fluid status and whether it is below or above optimal intravascular hydration.

System and method of assessing intra-arterial fluid volume using intelligent pulse averaging with integrated EKG and PPG sensors

A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing, to determine venous oxygen saturation is described. The system uses averaging of similar pulses based on Prior (or n−1) R-to-R pulse wave duration, and current (or n) R-to-R pulse wave duration for evaluation of the metabolic reserve and/or stress of the patient.

A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing to assess intra-arterial fluid volume is described. The system uses averaging of similar pulses based on prior (n&#x2212;1; n minus 1) R-to-R pulse wave duration, and prior-prior (n&#x2212;2; n minus 2) R-to-R pulse wave duration, to determine a patient's fluid status and whether it is below or above optimal intravascular hydration.
