  • IDWG Between-treatment gain

Dialysis Movement CL

  • Diffusion solutes; UF fluid
  • Diffusion: waste UF: water Convection: drag

Catheter vs AV Access CL

Catheter

  • Acid-base check → pH
  • Air risk → Air detector
  • Pressure alarm → Assess circuit

Machine + Circuit TE

  • Dialyzer Artificial kidney
  • Blood pump Moves blood
  • Arterial line Blood to dialyzer
  • Venous line Blood to patient
  • Air detector Stops air
  • Clamp Stops flow

Common Traps

Bruit vs thrill

  • Bruit is heard ≠ Thrill is felt

UF vs diffusion

  • UF removes water ≠ Diffusion removes solute

Tech vs nurse

  • Tech reports changes ≠ Nurse evaluates care

Alarm silence

  • Investigate alarm ≠ Do not ignore

Catheter care

  • High infection risk ≠ Sterile technique matters

Post-weight vs target

  • Post-weight is actual ≠ Target is goal
