Low latency breathing frequency detection and monitoring on a personal computerLeskovšek, Matevž ...We demonstrate a low latency respiratory/breathing frequency detection system that is fast (<5 ms), easy to operate, requires no batteries or external power supply and operates fully via ... computer-standard USB connection. Exercisesin controlling ones breathing frequency, usually referred to as paced-breathing exercises, have shown positive effects in treating pulmonary diseases, cardiovascular diseases and stress/ anxiety-related disorders. We developed a breathing frequency detection system which uses two pairs of microphones to detect exhalation activity, eliminate noise from the environment and stream the recording data via USB connection to a personal computer. It showed 97.1% reliability (10 subjects) when monitoring breathing activity in non-guided free breathing and 100% reliability (10 subjects) when monitoring breathing activity during interactive paced-breathing exercises. We also evaluated the breathing frequency detection systems noise elimination functionality which showed a reduction of 84.2 dB for stationary (white noise) and a reduction of 79.3 dB for nonstationary (hands clapping) noise.Vir: Journal of medical engineering & technology. - ISSN 0309-1902 (Vol. 35, no. 6/7, 2011, str. 322-329)Vrsta gradiva - članek, sestavni del ; neleposlovje za odrasleLeto - 2011Jezik - angleškiCOBISS.SI-ID - 35725317
