- Promotes more effective blood flow to wound site*
- Controls the zone of hypo-perfusion surrounding the wound edge eliminating concern for ischemia*
- Increases proliferation of new granulation tissue*
- Gradual pressure cycling (in 5 mmHg increments)*
- Lower than traditional pressures provides gentle tissue massage resulting in less pain and better outcomes*
Benefits of Variable Pressure Therapy (VPT®) Technology:
- Intermittent negative pressure increases blood to the wound site more effectively than continuous negative pressure, and proliferation of new granulation tissue is significantly higher.1,2
- Prospera® NPWT devices with VPT® technology are engineered to deliver comfortable, massaging variable pressure therapy.
- Customizable time and pressure settings.
- Calibrated to increase and decrease in comfortable 5mmHg increments between -40mmHg and -80mmHg, providing a gentle massaging effect.
- Limits painful high and low pressure spikes.2,3,4
