摘要

声学检测原理对监测呼吸气流有潜在的用处。一种无源传感器已经在三个临床研究中进行了评估。其对呼吸暂停检测的敏感性和特异性明显高于脉搏血氧仪等。这种传感器现在正在工业化。提出了一种新的呼吸流量非接触检测原理。

Acoustic sensors for respiratory air flow-from basic principles to clinical evaluation and industrialization

Acoustic detection principles are potentially useful for monitoring of respiratory air flow. One passive sensor has been evaluated in three clinical investigations. Its sensitivity and specificity to apnea detection was found to be significantly higher than, e.g. pulse oximetry. The sensor is now being industrialized. Furthermore, a new principle for noncontacting detection of respiratory flow is demonstrated.
