Arterial blood pressure waveform in liver transplant surgery possesses variability of morphology reflecting recipients' acuity and predicting short term outcomes
Shen-Chih Wang, Chien-Kun Ting, Cheng-Yen Chen +5
Background: We investigated clinical information underneath the beat-to-beat fluctuation of the arterial blood pressure (ABP) waveform morphology. We proposed the Dynamical Diffusi…
Unsupervised Ensembling of Multiple Software Sensors with Phase Synchronization: A Robust Approach For Electrocardiogram-derived Respiration
Jacob McErlean, John Malik, Yu-Ting Lin +2
Objective: We aimed to fuse the outputs of different electrocardiogram-derived respiration (EDR) algorithms to create one EDR signal that is of higher quality. Methods: We viewed e…
Novel imaging revealing inner dynamics for cardiovascular waveform analysis via unsupervised manifold learning
Shen-Chih Wang, Hau-Tieng Wu, Po-Hsun Huang +3
Cardiovascular waveforms contain information for clinical diagnosis. By "learning" and organizing the subtle change of waveform morphology from large amounts of raw waveform data,…
Wave-shape oscillatory model for nonstationary periodic time series analysis
Yu-Ting Lin, John Malik, Hau-Tieng Wu
The oscillations observed in many time series, particularly in biomedicine, exhibit morphological variations over time. These morphological variations are caused by intrinsic or ex…
Differentiation of skin incision and laparoscopic trocar insertion via quantifying transient bradycardia measured by electrocardiogram
Cheng-Hsi Chang, Yue-Lin Fang, Yu-Jung Wang +2
Background. Most surgical procedures involve structures deeper than the skin. However, the difference in surgical noxious stimulation between skin incision and laparoscopic trocar…
Unexpected sawtooth artifact in beat-to-beat pulse transit time measured from patient monitor data
Yu-Ting Lin, Yu-Lun Lo, Chen-Yun Lin +2
Object: It is increasingly popular to collect as much data as possible in the hospital setting from clinical monitors for research purposes. However, in this setup the data calibra…
When interpolation-induced reflection artifact meets time-frequency analysis
Yu-Ting Lin, Patrick Flandrin, Hau-tieng Wu
While extracting the temporal dynamical features based on the time-frequency analyses, like the reassignment and synchrosqueezing transform, attracts more and more interest in bio-…
The Modeling and Quantification of Rhythmic to Non-rhythmic Phenomenon in Electrocardiography during Anesthesia
Yu-Ting Lin
Variations of instantaneous heart rate appears regularly oscillatory in deeper levels of anesthesia and less regular in lighter levels of anesthesia. It is impossible to observe th…
Real-time dynamics acquisition from irregular samples -- with application to anesthesia evaluation
Charles K. Chui, Yu-Ting Lin, Hau-tieng Wu
The first objective of this paper is to introduce a unified approach to the D/A conversion, a real-time algorithm referred to as {\it blending operator}, based on spline functions…
Using synchrosqueezing transform to discover breathing dynamics from ECG signals
Wu Hau-Tieng, Chan Yi-Hsin, Lin Yu-Ting +1
The acquisition of breathing dynamics without directly recording the respiratory signals is beneficial in many clinical settings. The electrocardiography (ECG)-derived respiration…
