Abstract :
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
