DETECTION OF PATENT DUCTUS ARTERIOSUS USING PHOTOPLETHYSMOGRAPHY

摘要

Methods and systems are described for detecting the likelihood of patent ductus arteriosus (PDA) in an infant using electrocardiogram and photoplethysmographic pulse signals obtained from the upper body and foot of the infant. A method for detecting the likelihood of a patent ductus arteriosus (PDA) in an infant comprising: a) obtaining or receiving electrocardiogram (ECG) signals from the infant; b) obtaining or receiving photoplethysmographic (PPG) signals from a site on the upper body (UB) of the infant, and optionally from a foot (F) of the infant; c) determining, for each PPG pulse the PPG pulse amplitude (AM) between the enddiastolic maximum and the following minimum of systolic decrease for the UB PPG pulses.
