Instruments for Pulse Wave Analysis and Measurement of Pulse Wave Velocity
2012Over the last few years, a lot of new instruments for pulse wave analysis or measurement of pulse wave velocity have been launched onto the market. It seems that their main aim is to supply operator-independent devices, which can perform faster, while the accuracy of the measurement or the scientific soundness of the algorithms used are of secondary ...

Analysis of the microcirculatory pulse wave: age-related alterations
2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015Morphological analysis of the pulse wave of central blood pressure signal is commonly used for the study of cardiac and vascular properties, but very few attempts were performed for analyzing the peripheral pulse wave of blood flow. In this work, we analyzed this waveform using classical methods, based on the application of FFT, followed by principal ...

Analysis of intracranial pressure pulse wave in experimental hydrocephalus
Child's Nervous System, 1994Much has been written about the relationship between the pulse pressure (PP) of the intracranial pressure pulse wave (ICPPW) and ventricle dilatation. Some data suggest that high PP is the cause of ventricle dilatation, and other authors have reported that high PP results from decreased intracranial compliance.

Variability Analysis on the Parameters of Pulse Wave
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010The variability of pulse wave was found and discussed recently. The cross-correlation of variability of the parameters of pulse wave was studied in this paper. We found that the variability of the features in time was closely related. However, the variability of the features in time had little correlation with that of the amplitude features of pulse ...

Techniques for the Morphological Analysis of the Pulse Wave
Biomedical Engineering, 2019A new technique for contour analysis of the pulse wave signal is proposed. It is based on spectral analysis of a sequence of replicated pulse waveforms. Comparative analysis of the sensitivity and specificity of the proposed indices was carried out in a sample of 45 volunteers of different ages and states of arterial health.

Performance analysis of pulse transducers for measuring pulse wave velocity
2009 IEEE International Conference on Control and Automation, 2009Continuous blood pressure (BP) measurement based on pulse wave velocity (PWV) requires acquiring two pulse waves from different locations of human body. Choosing suitable and effective pulse transducers is critical for measuring PWV accurately and stably.

Spectrum Analysis of Pulse Modulated Waves
Bell System Technical Journal, 1947The problem here is to find the frequency spectrum produced by the simultaneous application of a number of frequencies to various forms of amplitude limiters or switches. The method of solution presented here is to first resolve the output wave into a series of rectangular waves or pulses and then to combine the spectrum of the individual pulses by ...

Analysis of the pulsed wave interaction experiment
Journal of Geophysical Research, 1973Analytical methods used for the deduction of electron density profiles in the D region from the pulsed wave interaction experiment are reviewed briefly. These are found to be generally unsatisfactory, and a new analysis procedure is proposed. Its application is demonstrated by using simulated wave interaction measurements.

Analysis of Pulse Wave Amplitude Measurement Errors
Biomedical Engineering, 2020This article addresses the analysis of random errors in measurements of pulse wave amplitude due to the influences of interference and noises of different origins and intensities. Mathematical models of the main distorting factors affecting pulse wave measurements are described.
