Negative Pressure Wound Therapy

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Negative Pressure Wound Therapy

Unlike Hyperbaric Oxygen Therapy (HBOT) that employs a chamber with a pressure higher than 1 atmosphere absolute, negative pressure wound therapy (NPWT) uses a vacuum to enhance and promote wound healing in acute, chronic and burn wounds. In this medical procedure, a sealed wound dressing is attached to a pump that creates a negative pressure environment for the wound.

The vacuum helps to increase blood flow to the area and draw out excess fluid from the wound and depending on the type of wound type or location, it can either be applied continuously or intermittently. This type of therapy can be implemented for a few days to several months at a time.

The types of wounds that can benefit from negative pressure wound therapy, include:

  • diabetic ulcers
  • venous ulcers
  • arterial ulcers
  • pressure ulcers
  • first and second-degree burns
  • chronic wounds
  • wounds with large amounts of drainage
  • surgical and acute wounds at high risk for infection

Acelity V.A.C.Ulta Therapy System

Used in its V.A.C.ULTA™ Therapy System and other wound care products, Acelity’s SENSAT.R.A.C.™ Technology is a real-time pressure feedback system that adjusts its pump’s output, compensating for wound distance, wound position, exudate characteristics and patient movement. Source: Acelity.

The applied negative pressure in NPWT can range from -125 to -75 mmHg (-2.4 to -1.5 psi) depending on the type of wound and the patient’s tolerance. For this application, All Sensor’s DLV-005D with its digital output would be an easy way to measure the vacuum level for both the machine’s use and the health care provider’s and patient’s observation.

Pressure Injury Prevention Day 2017

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure Injury Prevention Day

Since 2013, the National Pressure Ulcer Advisory Panel (NPUAP) has striven to increase national awareness to prevent pressure ulcers. An event previously titled the World Wide Pressure Ulcer Prevention Day is now the World Wide Pressure Injury Prevention Day. This year, the World Wide Pressure Injury Prevention Day will be celebrated on November 16, 2017.

Pressure ulcer injuries or bed sores occur due to bed-ridden and comatose patients lying in the same position for an extended period of time. Sensing the patient’s movement or pressure distribution change is among the techniques that can alert caregivers to assist the patient’s movement and avoid pressure ulcers.

The NPUAP redefined the definition of pressure injuries during the NPUAP 2016 Staging Consensus Conference held April 8-9, 2016 in Rosemont (Chicago), IL.

“A pressure injury is localized damage to the skin and underlying soft tissue usually over a bony prominence or related to a medical or other device. The injury can present as intact skin or an open ulcer and may be painful. The injury occurs as a result of intense and/or prolonged pressure or pressure in combination with shear.”

The stages of a pressure injury are:

  • Stage 1 Pressure Injury: Non-blanchable erythema of intact skin
  • Stage 2 Pressure Injury: Partial-thickness skin loss with exposed dermis
  • Stage 3 Pressure Injury: Full-thickness skin loss
  • Stage 4 Pressure Injury: Full-thickness skin and tissue loss

Pressure injuries also result from the use of medical devices designed and applied for diagnostic or therapeutic purposes.
