Objective

To retrieve evolving respiratory measures in the first minutes after birth in normal neonates born at term using a respiratory function monitor.

Study design

We evaluated newborn babies delivered at term via cesarean after uncomplicated pregnancies. Immediately after birth, a respiratory function monitor with an adapted flowmeter and a face mask were applied at 2, 5, and 10 minutes after birth for 90 seconds in each period. We analyzed expired and inspired tidal volume, respiratory rate (RR), percentage of leakage, and number of analyzed breaths in each individual infant's recording using a respiratory research software.

Results

A total of 243 infants completed the study. The final data set included 59 058 (48.35%) valid observations for each of the variables representing the analysis of 32 801 breaths. With these data, we constructed a reference range with 10th, 25th, 50th, 75th, and 90th percentiles for expired tidal volume and RR. Tidal volumes plateaued earlier in female than in male infants. No correlation with delayed cord clamping, gestational age, maternal morbidity, or indication for cesarean delivery were established.

Conclusions

We have constructed a reference range with percentiles for inspired and expired tidal volumes and RR in newborn babies born at term for the first 10 minutes after birth. Reference ranges can be employed for research and can be useful in the clinical setting to guide positive pressure ventilation in the delivery room.

目的利用呼吸功能监测仪，了解正常足月新生儿出生后最初几分钟呼吸功能的变化。研究设计:我们评估无并发症妊娠后经剖宫产的足月新生儿。出生后立即，在出生后2分钟、5分钟和10分钟使用呼吸功能监测仪和适配的流量计，并戴上口罩，每次使用90秒。我们使用呼吸研究软件分析每个婴儿个体记录中的呼气和吸气潮气量、呼吸率(RR)、泄漏百分比和分析呼吸次数。结果共有243名婴儿完成了研究。最终数据集包括每个变量的59 058(48.35%)有效观察值，代表32 801次呼吸的分析。利用这些数据，我们构建了过期潮量和RR的参考范围，分别为第10、25、50、75和90百分位。女性婴儿的潮气量比男性婴儿更早达到稳定。与延迟脐带夹紧、胎龄、产妇发病率或剖宫产指征无相关性。结论建立了足月新生儿出生后10分钟内吸气、呼气潮气量和RR的百分位数参考范围。参考范围可用于研究，并可用于临床环境中指导产房正压通气。
