Frequently Asked Questions
Q: How much does the therapy unit weigh?
A: The therapy unit weighs about 2.4 lbs (about 1.08 kg) with an empty
canister installed.
Q: How long does it take to charge the battery?
A: It takes about six hours to fully charge the battery.
Q: How long will a fully charged battery last?
A: The battery charge will last up to 14 hours.
Q: The therapy unit is sometimes noisy. Why is this and what can I do
about it?
A: Though the therapy unit may be very quiet at times, it may also make
noises to enable the accurate delivery of negative pressure to the
wound. Noise may seem louder at night when surrounding noise level
is greatly decreased. When a leak is present, unit noise may increase and
the unit will begin to alarm. Once the leak is fixed, the unit will no longer
alarm and become quieter. The unit may also make a burping sound
occasionally.
Placing the therapy unit below the level of the wound may allow the
system to work more efficiently and more quietly. It is normal to hear on-
again, off-again noise from the ACTIV.A.C.
TM
Therapy Unit.
Q: What happens if the therapy unit alarms?
A: The therapy unit is built with your safety in mind. The therapy unit has
alarms that you can see and hear which will alert you to a potential
problem. Most of the time, the alarm can be easily fixed (see Alerts and
Alarms chapter). Review this information with your doctor or nurse, so
you are comfortable with this alarm system.
Q: How do I know if the therapy unit is working properly?
A: The Therapy Status Bar at the bottom of the touch screen displays
specific therapy information. The spinning icon shows that negative
pressure is active (see Therapy On or Off section). Another way to tell
negative pressure is active is the foam dressing will be collapsed. You
may see wound fluid may moving in the tubing.
Q: What if I do not hear an audible click when installing a canister onto
the therapy unit?
A: An audible click should be heard when installing the canister. If you do
not hear an audible click, gently pull the canister away from the therapy
unit. If it is properly installed, it will not come off.
Q: What steps should I take before bathing?
A: Do not take the therapy unit into the shower or tub. See the Therapy
Unit Disconnect section for more information. The clear drape is
waterproof; you may wash or shower with dressings in place. Take care
not to roll the edges of the drape while bathing.
