According to WebMD, CPR is the abbreviation for cardiopulmonary resuscitation, and ED is the abbreviation for erectile dysfunction. CPR is given when a victim is unresponsive, while ED is a health condition that occurs in males.
WebMD states that CPR has three steps, abbreviated as C-A-B. That stands for compression, airway and breathing. One must start chest compressions, open the airway and blow breaths into the victim to help him start breathing on his own.
There can be either physical, psychological or medicinal reasons for a patient's erectile dysfunction. WebMD notes that a lack of blood flow to the penis or excessive alcohol consumption can cause erectile dysfunction.
