Introduction: Cardiopulmonary resuscitation is a critical performance in pregnant women, and if it is done correctly mother and fetus will be rescued. Anatomic and physiologic changes in pregnancy should be considered. The fetus increases the oxygen demand and carbon dioxide production, so the function of cardiopulmonary system increases and consequently cardiac output, heart rate, minute ventilation, tidal volume and respiratory rate increase.
In airway management, since the respiratory tract is fragile and edematous, in applying supportive devices occurrence of hemorrhage and more edema should be considered. In breathing support we should avoid the increase or decrease of ventilation, since changes in Co2 and PH decreases placental perfusion. Because of pendulous breast and diaphragm heightening, cardiac massage should be done in the middle of sternum. Drugs are contraindicated in pregnancy, but tratogenicity should be afforded.
Conclusion: Finally, after five minutes if CPR was not successful cesarean section should be done, since it is an effective factor in better resuscitation of mother and will improve the survival and neurological state of infant.
