Abstract:
|
This study proposes a method for the characterization of respiratory patterns in chronic heart failure (CHF) patients with periodic breathing (PB) and nonperiodic
breathing (nPB), using the flow signal. Autoregressive modeling of the envelope of the respiratory flow signal is the starting point for the pattern characterization. Spectral parameters extracted from the discriminant frequency band (DB) are used to characterize the respiratory patterns. For
each classification problem, the most discriminant parameter subset is selected using the leave-one-out cross-validation
technique. The power in the right DB provides an accuracy of 84.6% when classifying PB vs. nPB patterns in CHF
patients, whereas the power of the DB provides an accuracy of 85.5% when classifying the whole group of CHF patients
vs. healthy subjects, and 85.2% when classifying nPB patients vs. healthy subjects. |
