Acute respiratory failure in pregnancy.

Pregnancy increases the risk for respiratory failure from to numerous pulmonary diseases. Adult respiratory distress syndrome, aspiration, venous air embolism, asthma, thromboembolism, and heart disease are etiologies shared by non-pregnant women. However, their management is complicated by complex physiologic changes during pregnancy. Amniotic fluid embolism and tocolytic-induced pulmonary edema are unique to pregnancy and must be added to the list of causes of respiratory failure. Diagnostics and supportive care is difficult and must be directed with the mother and the fetus in mind. This dictates a thorough understanding of maternal physiology, and the safety of drug use during pregnancy.
