While machines involved in CRRT differ in make <strong>and</strong> model, the<br />
concepts of CRRT do not change. An underst<strong>and</strong>ing of the goal<br />
will allow for nurses <strong>to</strong> adapt <strong>to</strong> the management of different<br />
CRRT devices.<br />
Despite the particular make <strong>and</strong> model, some characteristics are<br />
common place. Circuitry, warming devices, alarms <strong>and</strong><br />
programming are universal.<br />
Circuitry is clear <strong>and</strong> consists of;<br />
• a venous access line; usually colour indicated blue<br />
• an ‘arterial’ access line; colour indicated red<br />
• a bubble trap for ‘catching’ air that may be in the line<br />
before its return <strong>to</strong> the patient<br />
• an area of tubing compliant <strong>to</strong> a warming device<br />
• thickened areas of clear tubing which are manipulated by<br />
the peristaltic action of the machine pumps<br />
The Warming device is responsible for controlling the<br />
temperature of the replacement fluid prior <strong>to</strong> its entry in<strong>to</strong> the<br />
circuit. The importance of temperature control has been<br />
previously discussed in the care of the patient <strong>and</strong> observations.<br />
