Research Protocol

  • 5 sets of compression-only CPR stationary
    • visual and auditory feedback enabled

​

  • Minimum 15 minutes rest

​

  • Compression-only CPR in moving
    • visual and auditory feedback enabled

Trends

  • Compression depth is affected by motion

​

  • Depth tends to be shallower and to get lighter

​

  • Velocity & slope angle affect depth and rate

What We Learned

  • CPR can be performed in a moving toboggan

​

  • Quality of CPR in a moving toboggan is less than stationary CPR – consistent “lightening”

​

  • CPR can be performed at slope angles up to 27°

Does It Work?

  • April 6 2018
  • 31 yr old snowboarder collapsed
  • primary cardiac event
  • CPR on site and during toboggan transport
  • ROSC prior to EMS transport
  • Released from hospital Apr 19
