Pulse Wave Analysis

This cardiac output detector uses AT89C52 as the core MCU, carries the pulse signal sampling from pulse sensor into the SCM after A/D conversion, and then figures out the cardiac output value and displays it on the LED. Software analysis works out the cardiac output value through five-point difference threshold for feature location of the pulse graph method theory. Experiment results show that the normal measured cardiac output is 5.411 L/min, the standard deviation of 0.873, while the catheter method as the gold standard of the mean 5.51 L/min, the standard deviation of 1.09. This system can meet the testing requirements of normal cardiac output. It is a non-invasive, convenient and new cardiac output measurement instrument with continuous testing, easy operation and low cost.

This paper describes the principle of detector for pulse and fill-liquid in one body, which is used to detect the body pulse and the number of liquid-drop within one minute when filling liquid. The detector works exactly and rapidly. It makes doctors and nurses disentangle from the annoyed daily grinds.

Based on the dynamic performance of radial force sensor detection and TCM pulse waveform technology, the paper described a kind of testing equipment being developed which tests both radial force sensor performance and the dynamic performance of the instrument of pulse detection. The device covers requirements for static and dynamic performance test of the radial artery pulse wave force sensor and pulse diagnosis instrument, thus it makes a change to compute frequency response of the sensor by directly measurement.

The source of ryokankyomishingeninto, which has been used for chronic respiratory and nasal diseases by using “sunken pulse” as an indication, is the Jin-kui-yao-lue text. We, however, experienced a case of allergic rhinitis presenting with “floating pulse” successfully treated with ryokankyomishingeninto. On the basis of this case, we investigated efficacy with ryokankyomishingeninto in 16 other patients who visited our outpatient clinic from January 2007 to March 2008, and who had the all of same remarks in pulse diagnoses and nasal symptoms, such as nasal obstruction, and rhinorrhea or respiratory symptoms such as wheeze and shortness of breathing. As a result, ryokankyomishingeninto improved symptoms in all these patients. All the adult cases had a “stuck feeling in pit of stomach”. Furthermore, they had either a “water dabbling sound in the stomach”, or “cold area on the epigastrium”.

Introduction: Recent researches have determined that decreased arterial elasticity by age is one of the Cardiovascular risk factors. The modification of arterial elasticity can be evaluated accurately by measuring PWV.\r\n', u'Objectives: To determine the age - related change in the arterial stiffness in healthy people and factors that change the arterial stiffness. \r\n', u'Subjects and methods: The study group consisted of 123 normotensive subjects, including 65 men and 58 women (mean age 51.2 \xb1 13.9 years). Aortic elasticity was assessed by measuring carotid - femoral pulse PWV using a Complior Colson device with 2 pressure transducers.\r\n', u'Results: The mean PWV in both gender groups was 10.2 \xb1 1.6 m/s. There was no significant difference in both the right and the left side of the body, as well as genders regarding PWV calculation. PWV was correlated with age (r = 0.56) and mean blood pressure index (r = 0.6). If PWV was measured on the left side, subjects with plaques in common carotid artery (proved by echo) had a higher PWV than those without carotid plaque presence. In returns, there was no significant difference in terms of PWV, if it was measured on the right side. The arterial PWV in normal subjects with CT/HDL index of more than 5 is higher than those with CT/HDL index of less than 5. There was no correlation between arterial PWV and hyper - cholesterolemia. \r\n', u'Conclusions: 1. Mean arterial PWV in the healthy subjects was. 10.2 \xb1 1.6 m/s. 2. Arterial PWV had a positive correlation with age, mean blood pressure index and CT/HDL index.\r\n', u'

It is difficult to extract signals under Low Signal Noise Ratio in biomedical signal processing. The elimination of movement artifact is really a bottleneck. A new solution for the movement artifact in pulse signal is proposed in this paper. According to pulse signal features, the signal is decomposed by using wavelet transform firstly. Then empirical mode decomposition (EMD) is applied to the wavelet coefficients in frequency band of useful signals, thus the signal and movement artifact can be distinguished effectively. Furthermore, the effectiveness of the proposed approach is verified by signal-to-noise ratio, energy ratio, cross correlation coefficient and power spectrum. This method can eliminate not only movement artifact, but also baseline wander and high-frequency noise. Thus, it provides an effective approach for the calculation of pulse rate and blood oxygen saturation.

At present, the English translation of TCM terms of pulse picture are various, which would bring confusion to the study and research on TCM diagnostics. In this paper, four principles for the translation are suggested by the authors: to distinguish the nomenclature of term with its connotative explanation, to translate with commonly used words in general, to create new word with common affix and to differentiate the terms similar in meaning. The authors tried to make choice the best translation for each kind pulse picture, and explained the reasons for selection.
