Abstract
The contribution (Qo/Qt) of gas-filled air spaces with reduced ventilation-perfusion ratio (VA/Qc) to the production of total venous admixture in nondistressed premature infant and newborn infants with transient tachypnea was assessed by the aADN2 and AaDo2. The mean value for Qo/Qt in both nondistressed prematures and infants with transient tachypnea was 0.08. In both groups this represented about 30% of total venous admixutre.
摘要
通过动脉-肺泡氮分压差（aADN2）和肺泡-动脉氧分压差（AaDo2）评估了通气-灌注比（VA/Qc）降低的含气腔隙对无呼吸窘迫的早产儿和患短暂性呼吸急促的新生儿总静脉混合血产生的贡献（Qo/Qt）。无呼吸窘迫的早产儿和患短暂性呼吸急促的婴儿的Qo/Qt平均值均为0.08。在两组中，这约占总静脉混合血的30%。
