OBJECTIVE
Previous studies have reported that the noise generated by dental equipment can interfere with the auscultation of respiratory sounds during sedation. Therefore, this study aimed to identify whether positing the acoustic sensor on the chest or cervical position would be least susceptible to interference from dental suction device noise, a prominent noise noted during respiratory sound monitoring during dental sedation.
METHODS
This prospective cohort study was conducted with 30 students. Sound intensity (dB) and frequency (kHz) levels from the dental suction were recorded from the cervical and chest regions under both oral and nasal breathing conditions and analyzed.
RESULTS
The mean intensity of dental suction sounds was significantly lower in the chest region compared with the cervical region, regardless of the breathing condition (P < .001). Furthermore, in the chest region, the mean sound frequency during oral breathing was significantly lower than that during nasal breathing (P < .01).
CONCLUSIONS
Our study suggests that monitoring respiratory sounds in the chest region can significantly reduce interference from noise generated by dental suction devices compared with monitoring at the cervical region.
目的
以往研究报告称，牙科设备产生的噪音会干扰镇静期间呼吸音的听诊。因此，本研究旨在确定将声学传感器置于胸部还是颈部位置时，受牙科吸引装置噪音（牙科镇静期间呼吸音监测时的一种突出噪音）干扰最小。
方法
对30名学生进行了这项前瞻性队列研究。在口腔呼吸和鼻腔呼吸两种条件下，记录颈部和胸部区域牙科吸引装置的声音强度（分贝）和频率（千赫）水平，并进行分析。
结果
无论呼吸条件如何，胸部区域牙科吸引声音的平均强度均显著低于颈部区域（P < .001）。此外，在胸部区域，口腔呼吸时的平均声音频率显著低于鼻腔呼吸时（P < .01）。
结论
我们的研究表明，与在颈部区域监测相比，在胸部区域监测呼吸音可显著减少牙科吸引装置产生的噪音干扰。
