Alternatives to conventional manual CPR have been
developed in an effort to enhance perfusion during
resuscitation from cardiac arrest and to improve survival.
Compared with conventional CPR, these techniques typically
require more personnel, training, and equipment, or they
apply to a specific setting. Some alternative CPR techniques
change in CPR sequence will require reeducation of everyone
who has ever learned CPR, but the consensus of the authors and
experts involved in the creation of the 2010 AHA Guidelines for
CPR and ECC is that the benefit will justify the effort.
