If the wound VAC device is alarming, check to see if the canister is full, the tubing is blocked, there's a leak, suction wasn't activated, or the battery is low. If the leak detection alarm sounds, inspect the clear, occlusive dressing to ensure that it remains firmly sealed against the skin.
Check to see if the canister is connected correctly and all tubing is securely fastened. Then check around the edges of the dressing, lightly pressing along the seal as you go. Pause the wound vac unit and then restart it. If this does not correct the issue, contact your caregiver or healthcare supervisor.
For those who are wondering how long a wound vac needs to stay on, most healthcare professionals recommend changing the dressing every 48 to 72 hours or at least three times a week. If the wound is infected, it may require the dressing to be changed more often.
You can listen for an air leak or signs that the dressing is not sticking to the wound well. Test the leak area by holding the dressing down with the palm of your hand. See if the pump then gets suction and the leak goes away.
Answers from doctors (1) The wound vac dressings need to be changed if therapy is stopped for more than 2 hours. When the wound vac is not operating and is on a wound, this causes an enclosed and warm environment that is not breathable and very suitable for bacterial growth.
"Blockage/Canister Full" - If there is a blockage or kink in the tubing or the canister is full, the audible alarm will sound. The canister should be changed or the tubing blockage removed. "Leak or High Flow" - If there is a leak at the wound dressing site or between the wound and the device, the alarm will sound.
A wound vacuum device removes this pressure over the area of the wound. This can help a wound heal in several ways. It can gently pull fluid from the wound over time. This can reduce swelling, and may help clean the wound and remove bacteria.
Following the observation of three Stage IV decubitus ulcers refractory to standard medical and surgical therapy for 10 months, a new vacuum-assisted closure device (V.A.C.) was initiated to speed wound healing.
Color is generally clear to pale yellow (normal), red (fresh blood), brown (dried or old blood), white (see above), or blue-green (usually indicative of Pseudomonas infection and should be cultured). The amount of drainage is generally documented as absent, scant, minimal, moderate, large, or copious.
If active bleeding develops suddenly or in large amounts during V.A.C. ® Therapy, or if frank (bright red) blood is seen in the tubing or in the canister, immediately stop V.A.C. ® Therapy, leave dressing in place, take measures to stop the bleeding and seek immediate medical assistance.
VAC therapy shouldn't hurt, and if it does it can indicate a complication. Many people experience discomfort when VAC bandages are changed. In some cases, a medical professional might administer pain medication 30 to 60 minutes before changing the bandages.
