Solutions
Access: Location
• Internal Jugular Vein –
• Lower risk of complication
• Simplicity of catheter insertion
• Femoral Vein –
• Optimal site for immobilized patient
• Easiest site for insertion
• Subclavian Vein –
• Higher risk of pneumo/hemothorax
• Associated with central venous stenosis
A veno-venous double or two single lumen venous catheters
Access: Important Considerations
• Refer to and follow the hospital protocol for specific guidelines
• Vascular Access ADQI* recommendations:
• Aspirate and discard heparin before flushing
• 20 to 30 CC syringe to assess patency
• Check for kinks/ clamps

Prismaflex Disposable Set
• Pre-connected, color-coded lines
• For ease in set loading
• Color-coded labels
• For easy hemofilter set identification
• 5 or 9L effluent bag
• With drain port for quick emptying
• Single priming/effluent bag with Y- connection
• Latex free
Prismaflex Disposable Set
• Single set for all therapy modalities
• Multiple sites for replacement fluid infusion
• Integrated pre-blood pump (PBP) infusion to the access line
• High flow blood lines with minimal pressure drop
• Clear Plastic Pump Cover
• Easy visibility of blood/fluid pump segments
• Electrostatic Discharger Ring
• To minimize ECG artifacts
• Integrated Barcode Reader
• For set recognition and automatic alarm limit settings
Prismaflex Disposable Set
• Pressure pods

Solutions for CRRT
Purpose • Dialysate and/or Replacement – provide diffusion and/or
convection
• Depends on mode of therapy
• Removal of unwanted solutes
• Restores electrolyte and acid/base balance to patient’s blood.
Buffer • Normalize blood pH
• Balances ongoing endogenous acid production
• Treat underlying metabolic acidosis/alkalosis
• Replace bicarbonate lost during CRRT
Preparation of Solution
5L ready-to-use solution obtained after breaking red frangible pin between two compartments
Interactive Display Screen Step-by-Step Instructions
•12 in. colored touch-screen•Displays a color-coded diagram of required actions
Status Lights
• Green - normal treatment conditions
• Yellow - advisory or caution alarm
• Red - highest priority alarm condition needing immediate intervention
Give a general indication of operating conditions.
