Set and on the IDL Set.
Replacement fluid
Fluid given to the patient during an exchange procedure to replace the
blood components removed.
Reservoir
Component of the tubing set cassette that contains the fluid to be
returned to the patient.
Reservoir filter
200-micron filter located at the exit of the reservoir used to filter the fluid
returned to the patient.
Return access
Refers to the patient access through which blood components and fluids
are returned.
Return flow rate
Speed at which blood is returned to the patient.
Return line
Line that carries fluid from the reservoir to the patient.
Return pressure
Force per unit of area on the blood flow as it is returned to the patient.
RF
Abbreviation for radio frequency.
Rinseback
Process that clears the channel of remaining cells and returns them to the
patient after the run.
rpm
Abbreviation for revolutions per minute.
Run
State during a procedure when apheresis is performed. The run starts
when the patient is connected and ends when a run target is attained.
Run target
One or more values that appear on the run values screen and on the run
targets screen that should be attained when the run ends. The system
predicts these values based on the primary run target.
Saline
Sterile 0.9% sodium chloride and water solution used to prime the tubing
set and to perform an apheresis procedure.
Saline rinse
Process that rinses the tubing set with saline before the run to clear the set
of any residual ethylene oxide, a by-product of sterilization.
Secondary plasma device
Device used to treat the separated plasma before it is returned to the
patient.
Sickle cell disease
Inherited blood disorder that affects the hemoglobin in RBC.
Single-needle access
Single patient access for both the inlet access and the return access.
Spillover
Condition when some RBC from the channel have entered the plasma
line.
SPD
Abbreviation for the procedure on the Spectra Optia system that is
performed with a secondary plasma device.
SPL
Abbreviation for sound pressure level.
Stem cell
