由于早产儿在标准汽车座椅上有缺氧和心动过缓的风险，本研究是为了在更大的样本中证实这一发现，调查新生儿重症监护病房的恢复期足月婴儿在汽车座椅上呼吸损伤，并确定其生理机制或相关机制。在中远-彼得森First Ride汽车座椅放置之前、期间和之后，对新生儿重症监护病房的50名康复婴儿进行了广泛的多通道测谎记录和肺功能测试。平均总动态顺应性、总肺阻力和呼吸功在汽车座椅上得到改善。30%的早产儿在汽车座椅上经历过缺氧、心动过缓或两者兼而有之；该组潮气量较低（p = 0.02）。在16例有异常表现的婴儿中，有11例的氧饱和度暂时与短暂性和混合性呼吸暂停发作有关。没有足月恢复期婴儿在汽车座椅上出现呼吸困难，无论初级诊断如何。我们的结论是，早产儿可能有呼吸损害的多因素性质，当在汽车座椅。如果要避免这样的呼吸问题，汽车座椅的进一步发展是必要的。
Because premature infants have been shown to be at risk for hypoxia and bradycardia when positioned in standard car seats, this study was done to confirm this finding in a larger sample, to investigate convalescent term infants in the neonatal intensive care unit for respiratory compromise in car seats, and to determine the physiologic mechanism or mechanisms responsible. Extensive multichannel polygraph recordings were obtained and pulmonary function tests were performed on 50 convalescent infants from the neonatal intensive care unit before, during, and after placement in a Cosco-Peterson First Ride car seat. Mean total dynamic compliance, total pulmonary resistance, and work of breathing improved in the car seat. Thirty percent of premature infants experienced hypoxia, bradycardia, or both in a car seat; in this group, tidal volume was lower (p = 0.02). In 11 of 16 infants with abnormal findings, oxygen desaturation was temporally related to episodes of short and mixed apnea. No term convalescent infant experienced respiratory difficulty in a car seat regardless of primary diagnosis. We conclude that premature infants may have respiratory compromise of a multifactorial nature when in car seats. Further development of car seats is necessary if such respiratory problems are to be avoided.
