My wound vac drainage varies greatly from 75 cc to none. I feel this variation has to do with how it is applied. Is this fluctuation normal?

This is a complex foot wound. I have diabetes #2 under control. I am always assured everything is fine, but at times I am also told the wound has been too wet. Any suggestion how I can assure the best treatment for my foot or other resource to refer to?

A better assessment of how well a negative pressure wound therapy dressing ("wound vac") is applied is how the skin around the wound looks when the dressing is removed. If the skin around the wound is very moist after removal of the dressing, the suction was not working very well and the drainage could have been leaking out from under the dressing instead of being pulled through the tube.
