to control, measure, and monitor the pressure in the drip
chambers of the extracorporeal circuit
to measure dialysate pressure
to calculate the transmembrane pressure (TMP).
The optional Noninvasive Blood Pressure Monitor (NIBP) tracks
the patient’s blood pressure using separate hardware. Refer to
Section 12.3 for more information on this optional feature.
12.1 EXTRACORPOREAL CIRCUIT
There are two configurations for the extracorporeal circuit pressure
monitoring:
Arterial and Venous
Arterial, Venous, and optional Single Needle (SND)
Extracorporeal circuit measurement and monitoring is
accomplished by the following hardware:
Luer connectors
Internal pressure transducer protectors
Electromagnetic valves
Pressure transducers
Vent filter (transducer protector)
Peristaltic pump and DC motor
Blood Pump Controller and Power Boards
Associated tubing
The luer connectors, transducer protectors, electromagnetic valves,
and pressure transducers are identical for each of the subsystems
(arterial, venous, and optional SND).
See Figures 12-1, 12-2, and 12-3 for the location of this hardware
in the Instrument.
