Poincaré plot analysis of cerebral blood flow signals: Feature extraction and classification methods for apnea detection

Rheoencephalography is a simple and inexpensive technique for cerebral blood flow assessment, however, it is not used in clinical practice since its correlation to clinical conditions has not yet been extensively proved. The present study investigates the ability of Poincaré Plot descriptors from rheoencephalography signals to detect apneas in volunteers.A group of 16 subjects participated in the study. Rheoencephalography data from baseline and...
