论文摘要
复发性呼吸道症状在婴儿中很常见，但肺功能测试的缺乏适合在婴儿中常规使用是一个公认的临床问题。在这项研究中，我们评估了在睡眠期间使用阻抗验尸（IP）在家庭睡眠期间测量的潮汐呼吸变异性（呼气变异性指数，EVI），作为36名婴儿（平均年龄12.8 [6-23个月）的较低气道阻塞的标记，并带有呼吸道呼吸症状。 EVI降低与肺部功能较低（VMAXFRC），哮喘风险较高和阻塞性症状有关，但与鼻充血无关。使用IP测量的EVI是婴儿肺功能测试的潜在技术。
Recurrent respiratory symptoms are common in infants but the paucity of lung function tests suitable for routine use in infants is a widely acknowledged clinical problem. In this study we evaluated tidal breathing variability (expiratory variability index, EVI) measured at home during sleep using impedance pneumography (IP) as a marker of lower airway obstruction in 36 infants (mean age 12.8 [range 6-23] months) with recurrent respiratory symptoms. Lowered EVI was associated with lower lung function (VmaxFRC), higher asthma risk, and obstructive symptoms, but not with nasal congestion. EVI measured using IP is a potential technique for lung function testing in infants.
