Filtrate or filtrate flow is the sum total of the dialysate, substituate, net
UF, citrate flow, and calcium flow. The filtrate or filtrate flow forms the
basis for the calculation of the calcium flow and is internally calculated
by the system.
Acute haemodialysis is the application of a hemodialysis therapy for the
treatment of temporary renal failure or acute exogenous poisoning.
The alarm function check is the verification of the proper function of the
alarm equipment.
The alarm limit is the measurement value which, when exceeded, will
trigger an alarm.
The arterial section is the section of the extracorporeal circuit from the
patient to the dialyser inlet port.
The arterial pressure is the pressure present at a defined site in the
arterial section between the vascular access and the pump.
The exchange volume is the fluid volume removed from the blood by
filtration which is replaced with substituate at a ratio of 1:1.
(The respective rate is indicated in ml/h or ml/min.)
The respective rate is the indicator at which speed the exchange is
performed.
The treatment time is the amount of time during which balancing is
switched on.
The blood leak monitor is a device used to detect blood in the filtrate or
dialysate, e.g., consisting of a sensor (detector), alarm generator, and
a sensitivity indicator, and controller, if necessary.
The blood pump is provided to transport the blood in the extracorporeal
circuit.
The calcium pump is used for adding calcium solution to the patient's
blood.
The calcium dose is the volume of calcium solution added to the
patient's blood in relation to the filtrate or filtrate flow. The dose is
specified in mmol per litre of filtrate (filtrate flow).
The calcium flow is the volume of calcium solution supplied to the
patient's blood per time unit.
