A new research paper published in the Journal of Emergency Trauma, and Shock has looked at the possible injury to the rescuers wrist while giving chest compressions.
The article describes the relationship between the amount of force needed to externally compress the chest the required depth and the possible injury to the rescuers' wrist, namely the scapholunate ligament The amount of force neccessary to compress the chest was recorded as being as much as 644 N (newtons), which equates to a (kilogram-force) of 65.6 Kgf.
The article proposes that the forces transmitted through the rescuers' wrists in the performance of external chest compressions during CPR are suffice to cause injury to the scapholunate ligament of the rescuer, potentially resulting in further cumulative trauma, degenerative changes, and eventual disability. Further biomechanical studies specific to this particular population should be performed.
The article makes an observation: "Compensation for worker injury maybe involved"
No doubt a point of interest for EMS managers everywhere...
