Nocturnal cough and wheeze are important symptoms when diagnosing any respiratory disease in a child, but objective measurements of these symptoms are not performed.
The aim of our study was to analyze the use of an automated detection system to assess breath sounds objectively in comparison to cough and wheeze questionnaires and to evaluate its feasibility in clinical practice.
Forty-nine recordings of thirty-nine children were processed (asthma n = 13; cystic fibrosis n = 2; pneumonia n = 5; suspicion of habit cough n = 7; prolonged, recurrent or chronic cough n = 13), and cough and asthma scores were compared to the objective nocturnal recordings. Time for audio-validation of recordings took between 2 and 40 min (mean: 14.22 min, (SD): 10.72). Accuracy of the automated measurement was higher for cough than for wheezing sounds. Nocturnal cough readings but not wheeze readings correlated with some of the corresponding scores.
To our knowledge this is the first study using a new device to assess nocturnal cough and obstructive breath sounds objectively in children with a wide variety of respiratory diseases. The assessment proved user friendly. We obtained additional information on nighttime symptoms, which would otherwise have remained obscure. Further studies to assess possible diagnostic and therapeutic benefits of this device are needed.
夜间咳嗽和喘息是诊断儿童任何呼吸道疾病的重要症状，但这些症状并没有进行客观测量。
我们的研究目的是分析使用自动检测系统客观评估呼吸音，与咳嗽和喘息问卷进行比较，并评估其在临床实践中的可行性。
对 39 名儿童的 49 份记录进行了处理（哮喘 n=13；囊性纤维化 n=2；肺炎 n=5；习惯性咳嗽怀疑 n=7；迁延性、复发性或慢性咳嗽 n=13），并将咳嗽和哮喘评分与客观夜间记录进行比较。音频验证记录的时间在 2 到 40 分钟之间（平均值：14.22 分钟，（SD）：10.72）。自动测量的准确性对于咳嗽声音高于喘息声音。夜间咳嗽读数而不是喘息读数与一些相应的评分相关。
据我们所知，这是第一项使用新设备客观评估患有各种呼吸道疾病的儿童夜间咳嗽和阻塞性呼吸音的研究。评估结果证明该设备使用方便。我们获得了有关夜间症状的额外信息，否则这些信息将不清楚。需要进一步研究该设备在诊断和治疗方面的可能益处。
