Significant physiological adaptations during pregnancy contribute to its successful outcome. These occur early in the pregnancy and continue throughout gestation, with complete reversal after delivery. Many changes that are normal during pregnancy are pathological should they occur in the nonpregnant woman. Adequate understanding of these normal changes is essential in the assessment of all pregnancies and in the management of those with complications. This article reviews the cardiovascular and pulmonary changes that occur during a normal gestation.
孕期显著的生理适应性变化有助于实现成功分娩。这些变化在孕期早期就已出现，并持续整个妊娠期，产后则完全恢复正常。许多在孕期属于正常的变化，若发生在非孕期女性身上则属于病理状态。充分了解这些正常变化对于评估所有妊娠情况以及处理有并发症的妊娠至关重要。本文综述了正常妊娠期间发生的心血管和肺部变化。
