ELEMENT Domain Model: HaemodialysisAccessRecirculationObservation

An ELEMENT to represent the result of a haemodialysis access recirculation measurement. Haemodialysis access recirculation occurs when dialysed blood returning through the venous needle reenters the extracorporeal circuit through the arterial needle, rather than returning to the systemic circulation. Haemodialysis access recirculation is measured as a percentage of the amount of blood reentering the extracorporeal circuit through the arterial needle.
