Leslie Geddes Demonstrates New CPR Technique (image) Purdue University Share Print E-Mail Caption Leslie Geddes, the Showalter Distinguished Professor Emeritus in Purdue's Weldon School of Biomedical Engineering, demonstrates a new technique for performing cardiopulmonary resuscitation. The method promises to be more effective than standard CPR because it increases nourishing blood flow through the heart by 25 percent. Geddes has developed the new method, called "only rhythmic abdominal compression," or OAC-CPR, which works by pushing on the abdomen instead of the chest.
