Increasing evidence shows that goal-directed hemodynamic management can improve outcomes in surgical and intensive care settings. Arterial waveform analysis is one of the different techniques used for guiding goal-directed therapy. Multiple proprietary systems have developed algorithms for obtaining cardiac output from an arterial waveform, including the FloTrac, LiDCO, and PiCCO systems. These...

Automated blood pressure measurements are usually characterized by poor operational reliability and a considerable degree of complexity in performing the measurement. This paper introduces a new technique for the indirect measurement of the systolic and diastolic blood pressure of an individual. The technique is based upon a statistically consistent relationship between the amplitude of the pul...

ST waveform analysis of fetal electrocardiogram (ECG) for intrapartum surveillance (STAN) is a newly introduced method for fetal surveillance. The purpose of this commentary is to assist in the proper use of fetal ECG in combination with cardiotocography (CTG) during labour. Guidelines and recommendations concerning CTG and ST waveform interpretation and classification are stated that were agre...

Formerly, microwave emissions accompanying hypervelocity impacts were confirmed experimentally. In this paper, two kinds of analyses, output waveform analysis and spectral analysis, are discussed for the purpose of clarifying the mechanism of microwave emissions. In output waveform analysis, the microwave pulse is simulated on the basis of a microcrack model in consideration of discharge curren...

Energy efficiency and safety are key issues to accurately stimulate neural tissues. A novel waveform has lately been proposed: the rising exponential waveform; nevertheless, no experimentation has been done using an active model of the membrane in order to validate these results. This paper proposes this analysis using several types of waveforms. The total power consumption, taking into conside...

The analysis of data derived by full-waveform laser scanning systems is of great interest. In this study, we estimate the impulse response of a laser scanning system capturing the waveform. Considering the impulse response of the system is important for precise waveform analysis. The characteristic of the system has to be mentioned to interpret the pulse properties in an accurate way. We determ...

A new mechanism for using Analysis-by-Synthesis techniques in low rate Waveform Interpolation based coders is introduced. The algorithm, implemented as part of a Multi-Prototype Waveform coder, exploits the high quality speech produced by interpolating unquantised speech-domain Prototype Waveforms. In the new scheme, a frame of Prototype Waveforms is quantised using two sets of codebook searche...
