Muscles used for chest compression under static and transportation conditions by David, Alexander, Marshall, Joshua, Keith, Kelsey

A study performed in Japan by Dr. Yasuda et. al detailed the muscle groups used in performing stationary CPR and while in a moving ambulance.  Results from this study published in "Muscles used for chest compression under static and transportation conditions" demonstrated that the rate and depth of compressions showed no significant difference between the two conditions, but that the overall effectiveness of CPR was significantly decreased while in a moving ambulance.

In the discussion of this article, many limits of this study are analyzed, the most relevant being the closed course on which the ambulance was driven during the study.  The speakers help to detail that CPR performed in the ambulance is highly ineffective without the use of an automatic device, i.e. the Lucas Device.  Further forethought might be needed when making transport decisions about a cardiac arrest patient receiving CPR.  Studies such as these help to give perspective and evidence based statistics which inform policy and may have impact on future protocols.
