Summary

Ambulance surfaces can cause dangerous pressure damage to patients. Studies show high interface pressures on stretchers and spinal boards risk capillary occlusion, necessitating pressure-relieving designs.

Area of Science:

  • Medical Engineering
  • Patient Safety
  • Biomedical Science

Background:

  • Pressure damage is a significant concern in healthcare settings.
  • Ambulance environments present unique challenges for patient positioning and support.
  • Existing ambulance surfaces may contribute to the risk of pressure-related injuries.

Purpose of the Study:

  • To investigate the risk of pressure damage from ambulance surfaces.
  • To quantify interface pressures on common ambulance equipment.
  • To identify susceptible areas prone to pressure injuries during ambulance transport.

Main Methods:

  • A single subject's ambulance journey was monitored.
  • Interface pressures (mmHg) were measured at the ischial tuberosities, sacrum, and heels.
  • Pressures on a standard ambulance stretcher and a spinal board were compared during stationary and moving conditions.

Main Results:

  • High interface pressure readings were recorded at susceptible body areas.
  • Measured pressures indicate a risk of capillary occlusion.
  • Potential for pressure damage development was identified.

Conclusions:

  • Standard ambulance stretchers and spinal boards may pose a risk of pressure damage.
  • Pressure-relieving surfaces should be considered for ambulance seats and stretchers.
  • Further research into optimized ambulance surface design is warranted.
