COMMON QUESTIONS for Nisus® Negative Pressure Wound Therapy
Question: How long is the battery life?
Answer: The battery will last up to 48 hours when using sleep mode and up to approximately 24 hours with normal use. The harder the pump has to work (i.e. larger, heavier draining wound), the shorter the battery life.
Question: How do I know the pump is charging?
Answer: A blue light will illuminate on the keypad above the power button. A lightning bolt will be displayed next to the battery indicator light also.
Question: Why is the blue light on, but the lightning bolt is not being displayed
next to the battery indicator while being charged?
Answer: Once the battery has achieved 100 percent charge, the lightning bolt will
disappear, this represents that the battery is fully charged. The blue light will stay
illuminated; this indicates that the pump is still connected to AC power.
Question: How often should I charge the pump?
Answer: The pump will alarm for low battery, and you can charge when alerted.
Most patients will charge the pump while they are resting and/or at night
Question: I was having moderate amount of drainage and now I have very little or none?
Answer: The longer that NPWT is applied, the less and less drainage you will have
and it is not uncommon to have no drainage
Question: Is it normal for the Nisus pump to turn on and off?

to maintain set pressure.
Question: How often will the Nisus pump turn on and off (Cycle)?

Question: How often do I empty the canisters?

Question: The pump is alarming leak, what does this mean?
Answer: This means that the dressing is not intact and is coming off.
Question: How do I fix a leak alarm?
Answer: Walk your finger around the outside of your wound pushing down on the drape. If this rectifies alarm, no further action is needed. If it is still alarming leak, listen for a hiss sound around the dressing, once identified place new drape over the area.
Question: The pump is alarming blockage, what does this mean?
Answer: This means the pump has detected a restriction of flow.
Question: How do I fix a blockage alarm?
Answer: Ensure the tubing is not clamped and/or kinked. If this does not rectify the alarm, please contact your medical provider.
Question: Do I have to remove the Nisus pump from the bag to change the canister?

Once the canister is replaced, place the Nisus pump back into the carrying bag.
