摘要

在潜水过程中监测潜水员的状态对于确保他们的安全和计划允许的身体活动是必不可少的。监测呼吸频率使用潜水员的呼吸声音作为参数可能用于此目的。本研究使用三种民用潜水设备进行:水肺潜水、闭路潜水和水面潜水。使用安装在潜水服气腔或远程水听器中的可穿戴声传感器来研究呼吸频率。呼吸频率监测也可以使用标准的水下语音通信系统。在开路水肺中,周期性呼吸声在20米的距离上是可分辨的,在100-140米的距离上,使用小波变换进行额外处理。使用闭路呼吸器监测潜水员呼吸道附近的吸入和呼出噪音。使用水面提供的潜水设备(潜水员在海底,深度8米)时,呼吸音是可分辨的。平均呼吸频率为16.4呼吸周期/分钟。研究人员可以评估潜水员的呼吸频率,而无需在呼吸器设计中进行侵入性干预。所获得的数据有助于潜水主管对潜水员进行远程监控。此外,数据可以输入个人减压电脑进行自我监控。

Acoustic Monitoring of Diver’s Respiratory Rate by Respiratory-Associated Noise

Monitoring the condition of divers during immersion is essential to ensuring their safety and planning permissible physical activity. Monitoring respiratory rates using a diver's respiratory sounds as parameters might be used for that purpose. This study was conducted with three types of diving apparatuses intended for civilian use: scuba, closed-circuit, and surface-supplied. Respiratory rates were investigated using wearable acoustic sensors installed in diving suit air cavities or remote hydrophones. The respiratory rate monitoring was also possible using a standard underwater voice communication system. Periodic breathing sounds are distinguishable in open-circuit scuba at a distance of 20 m, and a distance of 100–140 m with additional processing using wavelet transforms. The noise of inhalation and exhalation using closed-circuit breathing apparatus was monitored in the vicinity of the diver's respiratory tract. Respiratory sounds were distinguishable while using surface-supplied diving equipment (diver at the bottom, depth 8 m). The mean respiratory rate was 16.4 respiratory cycles per minute. The researchers could assess a diver's respiratory rate without invasive intervention in the breathing apparatus design. The data obtained were helpful for the remote monitoring of divers by the diving supervisor. Additionally, the data could be entered into a personal decompression computer for self-monitoring.
