General Questions

The Nimbus II PainPRO is designed to give you feedback to reassure you that it’s delivering medication at the proper rate and dosage. While the Nimbus pump is running, there will always be information on the screen to indicate that it is functioning appropriately. When the pump is infusing medication, a fluid bag icon will show near the top right corner of the display screen. The rate the pump is running will display in large font in the middle of the screen. Below the rate, a status bar is displayed alternating between 3 lines of information:


1. VTBI: the Volume of medicine To Be Infused


2. VINF: the Volume of medicine INFused so far


3. Next DB: After a bolus dose has been delivered, Next DB shows a lockout timer counting down the minutes and seconds remaining before the Bolus key will once again become active allowing a next Bolus dose.

As long as you see numbers on the screen and the fluid bag icon, your pump is working correctly. The green LED light will show for 10 minutes after any button press and then “go to sleep”. This is normal.

The fluid in the medication bag is clear, so while the pump is running, it’s unlikely that you will see the medication flow through the tubing. However, there will always be information for you on the screen to reassure you that the pump is running appropriately.

As per your physician’s instructions, press the Bolus key to request an extra dose of medicine. If a bolus dose has been enabled on your pump and is not within the demand bolus lockout period, the pump will deliver a bolus to help manage your pain.

If your infusion was programmed to allow a bolus dose, a “lockout” period will also have been preset by your anesthesia care team. If another bolus dose is requested during the “lockout” period the PainPRO pump will automatically deny the request until the lockout timer has counted down to zero.

Follow your physician’s instructions regarding bathing after your surgery. If it is allowed, be sure to keep the Nimbus II PainPRO pump out of the shower or tub away from running water so the pump does not get wet.

Follow your physician’s instructions regarding taking an extended trip or flying. The Nimbus II PainPRO pump can be used in-flight; however, your airline may have other questions or restrictions. It is advisable you may want to check with them first before arriving for your flight.

No, the Nimbus II PainPRO is not indicated for use in an MR environment.

When the PainPRO II is in Delay Start mode, a yellow or amber LED light will display near the right corner of the pump and an onscreen timer will count down in hours and minutes the time remaining before the pump starts the infusion. When the clock counts down to zero the pump will begin the infusion automatically. There isn’t anything else required for you to do.

While the PainPRO II pump is running in Delay Start mode, a patient has full control over their pain management. As instructed by your anesthesia care team, if the surgical pain increases, the patient can press and hold the bolus button for 3 seconds to cancel the delay. This action will deliver an immediate bolus of medication (as preset by your physician) and then begin the infusion when the bolus is finished.

When the pump is infusing medication, the Volume infused so far (VINF) is displayed on the bottom of the screen alternating between VTBI, VINF and Next DB.

Consult your anesthesia care team for any changes to your infusion therapy. They will determine whether a change to the medication dose is necessary and determine the best way to proceed.

Then press the down arrow to highlight and select “Cancel Dose” and press the key to cancel the bolus delivery before the pump resumes the infusion at the rate programmed by your anesthesia care team.
