title: Development of pneumoperitoneum after CPR.
abstract: BACKGROUND
  Chest compressions are performed routinely and have several well-known complications, however one of the rare complications is pneumoperitoneum caused by air entry through a perforation of the viscus. The exact cause of the perforation is not always clear. Furthermore, this rarely reported condition does not have clear management guidelines.
  
  
  METHODS
  We present an uncommon complication of pneumoperitoneum following successful resuscitation possibly caused by the presence of an orogastric tube at the time of compressions in a 79 year old Hispanic male. Following chest compressions, a distended and tympanic abdomen was noted and air seen under the diaphragm in X-ray imaging.
  
  
  CONCLUSIONS
  A review of previous case reports along with etiology and evaluation of risk factors is presented.
  
  
  CONCLUSIONS
  Although the exact cause of pneumoperitoneum cannot be confirmed, emergency personnel should be aware of the risk factors associated with viscus perforation during chest compressions.
