Pulse Wave Analysis

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”.

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.

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.

BACKGROUND AND OBJECTIVES: To investigate the impact of age on arterial stiffness and blood pressure (BP) variables in newly diagnosed untreated hypertension (HT). SUBJECTS AND METHODS: A total of 144 patients with newly diagnosed untreated HT were divided into two groups: young group (age < or =50 years, n=71), and old group (age >50 years, n=73). BP variables were measured on office or 24 hours ambulatory BP monitoring (ABPM). Parameters of arterial stiffness were measured on pulse wave velocity (PWV). Pulse wave analysis (PWA) was compared. RESULTS: Although office BP and pulse pressure (PP) were significantly (p<0.05) higher in the young group than in the old group, BP and PP on ABPM were not significantly different. Central systolic BP and PP, augmentation pressure, augmentation index on PWA, and PWV were significantly higher or faster in the old group compared to that in the young group. Age showed significant positive correlation with both PWV and PWA variables in the young group with HT. However, age only showed significant positive correlation with PWV in the old group with HT. In the young group with HT, PWA variable showed better correlation with age than PWV. CONCLUSION: Considering BP levels on ABPM, office BP is prone to be overestimated in young patients with HT. Parameters of arterial stiffness measured by PWV and PWA were more affected by age rather than by BP level in patients with HT. Therefore, PWA variable might be a more sensitive marker of arterial stiffness in young patients with HT. However, PWV might be a better marker for old patients with HT.

PURPOSE: The purpose of this study was to develop a vital signs e-book for undergraduate student nurses and evaluate the content, system and student satisfaction. METHOD: This study was done in three stages, the development of a vital signs e-book, implementation and evaluation. The subjects were 73 undergraduate student nurses in Y university. RESULT: Thirty one learning objectives were used to create the contents. A set of 5 chapters and 18 subsections were defined after validation from nurse educators. The e-book is available at http://123.134.207.23/ebook/vitalsigns. Analysis of the questionnaires showed a mean score for content, system and students satisfaction of 3.17 +/- .73, 3.11 +/-.79, and 2.96 +/-.74 respectively out of a possible 4 points. CONCLUSION: Nurse educators should provide quality and effective web-based courses that meet undergraduate student nurses' learning needs and they should incorporate web-based learning into traditional teaching to meet the demands of nursing education.

OBJECTIVES: The role of rheumatoid factor (RF) in vascular stiffness and cardiovascular risk in subjects without joint symptoms remains unclear. We investigated vascular stiffness in subjects without joint symptoms using pulse wave velocity (PWV), calculated Framingham risk scores (FRS), an estimator of cardiovascular risk, and analyzed whether vascular stiffness and FRS were affected by RF. METHODS: Two hundred forty-two subjects were included in this population-based study. RF was quantified with turbid immunometry using a cut-off of RF > 15 IU/ml to denote RF positivity. Information was then obtained on joint symptoms. Brachial-ankle PWV (baPWV) was measured using an automated device. RESULTS: Of the 242 subjects, 15 were RF-positive. RF-positive subjects without joint symptoms had a higher baPWV and FRS than RF-negative subjects without joint symptoms, but the difference did not reach statistical significance. However, when we stratified the subjects into two groups (group A – high RF: RF ≥ 40 IU/ml; group B – low RF: RF < 40 IU/ml), group A showed significantly higher baPWV (1640.7 ± 179.6 ㎝/s vs. 1405.7 ± 225.7 ㎝/s, P = 0.008) and FRS (25.7 ± 4.87 vs. 11.8 ± 9.6, P < 0.001). Multiple regression analysis was used to examine potential confounders, and RF exhibited significant but modest effects on baPWV (adjusted R-squared = 0.038, P = 0.030). CONCLUSIONS: In a sample of the general population without joint symptoms, higher levels of RF were associated with increased vascular stiffness, suggesting a pathophysiologic link between RF and endothelial dysfunction.
