Vacuum Devices: There is too much variability to answer your question. So many factors are involved with wound healing, and especially so with pressure ulcers, that giving a time frame is difficult without seeing the wound and knowing other information (how large, how deep, other medical conditions, location, underlying bone infections, etc.).

This is a loaded question, but a rule of thumb is that if all of the underlying factors that contributed to the wound are addressed, a wound should respond significantly to VAC therapy within 4 weeks. If it hasn't by then, it probably won't.

Depends: The length of time varies from patient to patient and depends on so many factors that a general statement can not be made. The vac is a fabulous device and works very well. Give it time to work and provide pressure relief with maximal nutritional support.

The key to healing pressure sores is removing the source of the pressure. The KCI Wound VAC is a great device but it requires a sponge in the wound which is then sucked down, forming a hard mass. If the patient is still allowed to lie or sit on the ulcer, this can make the wound worse! The VAC works best (and fastest) on wounds with loose, floppy edges with strict avoidance of external pressure.
