Monitoring and analysis of lung sounds remotely
Department of Instrumentation Technology, RV College of Engineering, Bangalore, Karnataka, India
Abstract: Visual and auditory analysis of respiratory sound signals promises improved detection of certain types of lung diseases. LabVIEW software was used to design a system that monitors the respiratory activity of the patient. The program developed calculates the respiratory rate, displays the time expanded waveform of the lung sound, and computes the fast Fourier transform and short-time Fourier transform to present the power spectrum and spectrogram respectively. These parameters are transmitted synchronously to the remote station using the Internet for online monitoring of the patient.
Keywords: lung sounds, power spectrum, spectrogram, monitoring, remote, LabVIEW
