a) Outline the classification system for pressure induced skin and soft tissue injuries.
b) List six risk factors for the development of pressure injuries. (30% marks)
c) List the mechanisms by which negative pressure wound therapy systems (VAC systems) potentially contribute to wound healing. (20% marks)
d) List six complications of negative pressure wound therapy systems. (30% marks)
a) This is the NPUAP/EPUAP system (2009), which goes by many names, and which is endorsed by the Australian Wound Management Association and the Pan Pacific Clinical Practice Guideline for the Prevention and Management of Pressure Injury.
b) Risk factors for pressure injuries are numerous; one might expect that any six of the following would have been enough:
c) Several mechanisms are proposed to explain how VAC works.
d) Complications of VAC systems:
