In this module we explore the physics behind negative pressure wound therapy. Some of the key questions we will explore include how negative pressure is created and delivered to the wound bed, and how changes in pressure lead to fluid removal. 

Finally, we explore several of the clever adaptations that have been made to negative pressure wound therapy systems to enhance their function.

Please click on all + signs that you see in the course. Please click on all visual cards that ask you to "flip" them. You will not be able to advance to the next section unless you do and answer any questions in that section.

There will be a some questions at the end of some sections of the training to check for comprehension.

Good luck and enjoy the course.


This course is CPD certified.


To explain the physics of negative pressure.

  • Describe how negative pressure is created and the importance of a pressure gradient
  • Explain how fluid removal occurs during NPWT

To describe the ways in which NPWT devices have been modified to perfect fluid and pressure dynamics.

To describe the fundamental requirements of NPWT that need to be delivered for the full mechanisms of action to be achieved.


By completing/passing this course, you will attain the certificate Certificate CPD The Physics of NPWT
