Summary

The medium static air seat cushion effectively reduced peak pressures and improved pressure distribution for patients in the operating room. This finding helps prevent hospital-acquired occipital pressure injuries.

Area of Science:

  • Medical Devices
  • Patient Safety
  • Surgical Care

Background:

  • Hospital-acquired occipital pressure injuries are a significant concern in perioperative settings.
  • These injuries contribute to patient morbidity and mortality.
  • Preventable pressure injuries necessitate innovative solutions.

Purpose of the Study:

  • To identify occipital cushions/pillows that minimize peak pressures.
  • To evaluate cushions that maximize pressure distribution surface area.
  • Utilizing pressure mapping technology for objective assessment.

Main Methods:

  • A quality improvement project was conducted with 3 operating room volunteers.
  • Pressure mapping technology was employed to test 5 different pillows.
  • Tested items included standard pillows, fluidized positioners, static air cushions, and foam donuts.

Main Results:

  • The non-powered fluidized positioner exhibited the highest average and peak pressures.
  • A medium-sized static air seat cushion demonstrated the lowest pressures for most volunteers.
  • No tested head cushion consistently provided a larger pressure distribution area.

Conclusions:

  • The medium static air seat cushion showed superior pressure redistribution properties.
  • The non-powered fluidized positioner was least effective in pressure redistribution.
  • Findings guide the selection of optimal support surfaces to prevent pressure injuries.
