Congenital heart lesions can be classified according to hemodynamic characteristics related to pulmonary blood flow patterns: increased, normal, or decreased, lesions with decreased pulmonary blood flow characteristically present with cyanosis. This article briefly reviews differential diagnoses for the presenting sign of cyanosis. Additionally, this article provides a comprehensive overview of cardiac physiology of lesions with decreased pulmonary blood flow. This information provides a foundation of knowledge for the recognition of acute symptoms in the newborn period and an understanding of immediate stabilization and medical and surgical interventions related to each diagnosis.
肺血流增加、正常或减少，肺血流减少的病变通常表现为发绀。本文简要回顾了发绀这一表现体征的鉴别诊断。此外，本文还全面概述了肺血流减少病变的心脏生理学。这些信息为识别新生儿期的急性症状以及理解与每种诊断相关的即时稳定处理、内科和外科干预提供了知识基础。
