Overview

Prospective crossover study demonstrates mechanical CPR improves compression quality and rescuer safety during ski patrol transport, suggesting significant utility in complex terrain.

Key Points

  • To evaluate and compare the CPR quality metrics and rescuer safety of mechanical versus manual chest compressions during ski patrol toboggan transport in complex terrain.
  • Conducted a prospective crossover trial from November 2024 to May 2025 simulating ski slope rescue scenarios.
  • Performed 10 downhill runs comparing manual compression-only CPR against mechanical chest compressions using a Bluetooth-capable CPR mannikin to record performance metrics.
  • Mechanical CPR demonstrated significantly superior compression fraction, compression rate, and correct compression positioning relative to manual CPR.
  • No significant differences were identified between manual and mechanical CPR in total scenario time, compression depth, or pause duration.
  • Manual CPR presented marked safety risks to providers, resulting in three ski patrollers being ejected from toboggans across three separate trials.
