Pulmonary Function Changes during Pregnancy
|

Abstract
|
|
|
A wide variety of physiologic changes occurring during pregnancy influence maternal respiratory function and gas exchange. The major factors that alter respiratory function are the mechanical and biochemical changes that routinely accompany the pregnant state. Although such changes generally gave measurable effects on pulmonary function tests, ventilation, and gas exchange, the physiologic sequelae are only sometimes perceived by the pregnant woman. The patient with underlying pulmonary disease who becomes pregnant not only experiences the effects on normal mechanical and biochemical events, but may also find the natural course of her pulmonary disease altered. In addition, she may be at increased risk for complications of pregnancy and potential adverse effects of drugs on fetal development.
The purpose of this review is to outline the factors that influence the respiratory system during pregnancy and to discuss their effects in normal women.
