Here’s a segment from a piece delivered at the 2017 ICAR (International Commission for Alpine Rescue) conference based in Soldy, Andorra.
The segment covers some work on suspension trauma. Although very rare, the findings of the research clearly illustrates the need to remove casualties from being suspended in a harness as quickly as possible if they are unresponsive (i.e. not moving/unconscious).
This information should shape the way we consider our rigging, in other words do we rig for rescue so we can very quickly lower someone to somewhere we can get them in a horizontal position, rather than shifting to what may be a lengthy haul?
Worth a watch…
