Abstract:

In this paper, a new and non-invasive method has been proposed to retrieve respiratory effort component from photoplethysmography (PPG) sensor. The PPG signals are recorded using a commercial wrist worn device. Inverse synchrosqueezed wavelet (ISSW) transform has been applied to reconstruct the respiratory component and then to derive respiratory effort component. The reconstructed respiratory component and the respiratory effort signal from PPG are shown to be highly correlated with airflow signal and extracted respiratory effort obtained using a thermocouple secured under nose. The findings in this paper can make significant changes in various applications such as for sleep analysis, where continuous monitoring of respiratory effort from a wrist worn sensor unobtrusively is crucial for identification of various sleep abnormalities such as sleep apnea.
