Respiratory flow detection with the aim of detecting sleep-related breathing disorders plays a major role in polysomnography. Due to the fact that pneumotachographs are too bulky and not suitable for measurements during sleep, the ThorAKUSTIK system has been developed. By attaching a noise sensor right next to larynx, it determines the respiratory flow in an acoustic way.
The ThorAKUSTIK system as well as a pneumotachograph were applied simultaneously. The correlation between those two methods has been calculated.
We investigated twenty male subjects. All of them were non-smokers.
The ThorAKUSTIK-System showed a highly positive correlation (r = 0.89 to 0.91; p < 0.01) and was able to measure the respiratory flow in a reliable way.
The ThorAKUSTIK-System allows a long-term live monitoring and has the potential to be used in several clinical departments. Larger studies are necessary to verify the application in the clinical routine.
旨在检测与睡眠相关呼吸障碍的呼吸流量检测在多导睡眠图中起着重要作用。由于呼吸速度描记器体积过大且不适合在睡眠期间进行测量，因此开发了ThorAKUSTIK系统。通过在喉部旁边安装一个噪声传感器，它以声学方式确定呼吸流量。
同时应用ThorAKUSTIK系统和呼吸速度描记器。计算了这两种方法之间的相关性。
我们调查了20名男性受试者。他们均为非吸烟者。
ThorAKUSTIK系统显示出高度正相关（r = 0.89至0.91；p < 0.01），并且能够可靠地测量呼吸流量。
ThorAKUSTIK系统允许进行长期实时监测，并且有可能在多个临床科室中使用。需要进行更大规模的研究以验证其在临床常规中的应用。
