Did You Know: Dual Wave bolus delivers a combination of an immediate Normal bolus followed by a Square Wave bolus. The Square Wave portion is delayed evenly over a period of time. A Dual Wave bolus is useful for meals with both rapidly and slowly absorbed carbohydrates.

Important: It is important you consult with your healthcare professional before using a Dual Wave bolus.

To set up a Dual Wave bolus, you must first turn on the dual/square bolus option.

  1. Make sure the Dual/ Square Wave option is on.
    • For MiniMed 530G (551/751), Revel (523/723)
      Main Menu > Bolus > Bolus Setup > Dual/Square Bolus
    • For 522/722, 515/715, 512/712
      Main Menu > Bolus > Dual/Square Bolus
  2. Select On, then press ACT. The feature is now on. Exit the menus.
  3. Calculate your food and/or correction bolus amount.
  4. Go to the BOLUS TYPE screen.
    • Main Menu > Bolus > Set Bolus
  5. Select Dual Wave Bolus, then press ACT. The SET DUAL BOLUS TOTAL screen appears.
  6. Enter the desired amount for the total dual bolus units. This amount is the total of Normal and Square Wave bolus units. Press ACT.
  7. The next screen flashes the amounts of Now (Normal) and Square Wave portions of the Dual Wave bolus. The screen also shows the percentage amount of each portion. Press UP or DOWN to change the percentage/number of units.
  8. The SQUARE DURATION screen appears. Enter the amount of time you want the Square Wave bolus to last, then press ACT.

Note: If you have BG reminder turned On, the BG REMINDER DURATION screen displays. It allows you to set the duration before you are reminded to check your blood glucose after a bolus.

  1. The BOLUS DELIVERY screen appears with an open circle indicating that your pump is in Special mode. The pump beeps/vibrates at the start of the bolus. During bolus delivery, the pump will return to the HOME screen. The pump beeps/vibrates at the end of the bolus and the open circle disappears.

Note: During delivery of a Square Wave bolus, you will not be able to do the following pump functions:

  • Change the max bolus amount
  • Change the scroll rate
  • Disable or deliver Dual and Square Wave boluses
  • Rewind or fill the cannula (or fixed prime)
  • Change the active insulin time
  • Run a self-test
  • Access the User Settings menu

All other pump functions are still available during the Square Wave bolus.
