Physio Crate A Signal Plant toolbox for respiratory

Physio. Crate: A Signal. Plant toolbox for respiratory, blood pressure and EMG signal anylysis P. Nejedly, J. Virgala

GPU accelerated filtering library for Signal. Plant • Plugins for analysis of blood pressure and respiration BP: slp 01 a. edf - channel BP RESP: slp 01 a. edf - channel Resp hp 2 p. h 5 - channel 1 • Plugin for EMG analysis EMG : hp 2 p. h 5 - channel 3, 4

Plugins for analysis of blood pressure and respiration • • • Systole and diastole detection Systolic and diastolic function Heart rate variability • • • Overall features statistics Artificial areas extraction Analysis of segments of interest

Plugins for analysis of blood pressure and respiration Realisation • FIR filter – Low pass 10 Hz, order 50 • Extremes detection in floating window • Percentil condition Systol detection results • TPR=99. 33% • PPV=99. 39% • MIH-BIH polysomnographic db.

Plugins for analysis of blood pressure and respiration

Respiration analysis • • Inspiration and expiration detection Respiration amplitude Respiration freqeuncy Minute ventilation Results • TPR=93. 27% • PPV=92. 80% • Capno. Base database

EMG analysis plugin Requirements • Higher EMG activity detection • Usage of standardised methods Realisation • FFT filter – Band pass • Abs(x), x^2, envelope • Treshold: %max, percentile, user-defined
