This paper proposes a method for electrocardiogram (ECG) heartbeat detection and recognition using adaptive wavelet network (AWN). The ECG beat recognition can be divided into a sequence of stages, starting with feature extraction from QRS complexes, and then according to characteristic features to identify the cardiac arrhythmias including the(More)
Ventilator weaning is the process of discontinuing mechanical ventilators from patients with respiratory failure. This study designed a clinical decision support system (CDSS) using support vector machine (SVM) to predict if a patient can be weaned from mechanical ventilator successfully. A filter method based on logistic regression analysis (LRA) and a(More)
In Taiwan, the number of the patients needing dialysis increases rapidly in recent years. Because there is risk in every hemodialysis session, monitoring physiological status, such as blood pressure measurement every 30 min to 1 h is needed during about 4 h hemodialysis process. Therefore, an assisted measurement on blood pressure is needful in dialysis(More)
Tissue injury and its ensuing healing process cause scar formation. In addition to physical disability, the subsequent disfigurements from burns often bring negative psychological impacts on the survivors. Scar hypertrophy and contracture limit the joint motion and body function of the patient. With fast development of the current available technologies(More)
The bilateral photoplethysmography (PPG) analysis for arteriovenous fistula (AVF) dysfunction screening with a fractional-order feature and a cooperative game (CG)-based embedded detector is proposed. The proposed detector uses a feature extraction method and a CG to evaluate the risk level for AVF dysfunction for patients undergoing haemodialysis(More)
Baroreflex sensitivity is recognized for its prognostic relevance to cardio-vascular and cerebro-vascular risks. However, little is known about the long-term outcome of baroreflex function in patients with carotid stenosis undergoing carotid stenting. Heart rate variability and cardio-vascular autonomic function, including baroreflex sensitivity, were(More)
This study proposes multiple-site hemodynamic analysis of Doppler ultrasound with an adaptive color relation classifier for arteriovenous access occlusion evaluation in routine examinations. The hemodynamic analysis is used to express the properties of blood flow through a vital access or a tube, using dimensionless numbers. An acoustic measurement is(More)
Recently, the quantitative ultrasound (QUS) technique has been widely applied for the characterization of tissues. For example, it can be used for the quantization of Achilles tendons based on the broadband ultrasound attenuation (BUA) and speed of sound (SOS) when the ultrasound wave passes through the tissues. The main purpose of this study is to develop(More)
