• Transfusion of Packed Red Blood Cells
  • Administration of warm fluid to the following patients:
    • Paediatric patients
    • Burns patients
    • Patients with hypothermia 
  • Patients undergoing MRI
  • Do not administer medications through the MEQU warmer
Patient Factors & Considerations
  • Air embolism can occur with any intravenous infusion.
  • Prime the MEQU warmer with crystalloid solutions and closely monitor for trapped air inside the giving set.
  • Disconnection of the power pack from the MEQU warmer will immediately stop fluid warming, but will have no effect on flow rate.
  • Use aseptic technique.
  • Gather the power pack & MEQU warmer cartridge.
  • Remove the MEQU warmer from its foil packaging.
  • Disconnect the tamper proof seals.
  • Separate the red and blue luer locks.
  • Connect a primed blood compatible giving set to the male (blue) luer lock. 
  • Open the giving set roller regulator until the MEQU warmer is primed, ensuring all the air is flushed.
    • Note: if the giving set is already primed with blood products, flush the MEQU warmer with a syringe of crystalloid solution. 
  • Close the roller regulator.
  • Secure the disposable cartridge to a suitable location (usually the patients arm or leg) by removing the protective film on the adhesive tape and wrapping it around the extremity.
  • Connect the female (red) luer lock to the IV catheter via bung or extension set. 
  • Connect the plug from the Power Pack to the warming cartridge. A blinking green light indicates the cartridge is warming. A solid green light indicates the unit is warming fluid to the correct temperature.
  • Adjust the flow of fluid to the required drip rate through the roller regulator.
  • Monitor closely for signs of extravasation.
