Respiratory support in the delivery room remains challenging. Assessing chest rise is imprecise, and mask leak and airway obstruction are common problems. We describe recordings of respiratory signals during delivery room resuscitations and discuss guidance on positive-pressure ventilation using respiratory parameters and exhaled carbon dioxide (ECO2 ) during neonatal resuscitations.
Observing tidal volume and ECO2 waveforms adds objectivity to clinical assessments. ECO2 could help assess lung aeration and improve lung recruitment immediately after birth.
产房内的呼吸支持仍然具有挑战性。评估胸廓起伏不准确,面罩漏气和气道阻塞是常见问题。我们描述了产房复苏期间呼吸信号的记录,并讨论了新生儿复苏期间使用呼吸参数和呼出二氧化碳(ECO2)进行正压通气的指导意见。
观察潮气量和ECO2波形可使临床评估更加客观。ECO2有助于评估肺通气情况,并在出生后立即改善肺复张。
