Oscillometric blood pressure measurement
Benešová, Lenka ; Janoušek, Oto (referee) ; Šikner, Tomáš (advisor)
The bachelor thesis deals with the implementation of an oscillometric blood pressure measurement method in LabVIEW. It presents the research of blood pressure measurement methods focusing on an oscillometric method. It describes the study of different methods of measuring the systolic and diastolic blood pressure from an oscillometric curve and the implementation of two of these methods in LabVIEW. The accuracy of the implementation was verified with an auscultation technique on 37 measured subjects.
The problems of self-monitored blood pressure
Basic theoretical background: The hypertension is a disease in which the blood pressure 140/90 mm Hg, and these values are measured at at least two of the three measurements. Arterial hypertension is one of the most common limit disease with a high prevalence in the adult population in industrialized countries. Aims of the thesis: The aids od the thesis was as to determine whether patients adhere to the principle of self-monitoring of blood pressure using a pressure gauge in the upper arm at home. Furthermore, to determine the most common mistakes patients during self monitoring of blood pressure using a pressure gauge in the upper arm at home. These targets were established research questions: Do they adhere to treating patients with hypertension guidelines for the measurement of blood pressure gauge in the upper arm? Are the errors existing in the measurement of blood pressure gauge in the upper arm? The last research question was: What mistakes do occur, the measurement of TK (gauge in the upper arm) in the home environment for patients undergoing treatment with hypertension most often? Methodology: The empirical part of bachelor work was done using the qualitative research, which was chosen for the data collection technique using individual semi-structured interviews, supplemented by observation in patients with hypertension that home blood pressure measurement using the upper arm a tonometer. The data were collected in March 2014 with respondents, who were selected using the snowball technique. The interview included a pre-prepared questions. Answers of respondents have been recorded in the recording sheet and the recording equipment. The observation was made an observation sheet with the criteria and then created a table below describes the criteria for assessing organizations. The group consisted of 8 respondents. There are four men and four women. The respondents were familiar with the questions in advance and the actual interview was recorded in writing and the recording equipment. All respondents agreed with the observation that took place before the interview. Results: The research results show that more than half of the respondents do not comply with dietary measures (see diagram 2). Another category was focused on the use of medication. Five of the eight respondents taking medications regularly Most respondents answered o the question regarding the occurrence of adverse effects that they do not have side effects.Only two respondents have indicated adverse effects (see diagram 4). The startling finding was that only half of the respondents were aware of adverse effects. In the category of blood pressure measurements showed that all except for the respondent 1, other respondents carried out to measure its pressure in the morning and 1 respondent plus two others measurements performed in the evening (see diagram 6). Each of respondent was asked different frequency measurement, only a few of the respondents agreed (see diagram 5).This category contained three subsections in which we dealt as the position of the respondents have the measurement of your blood pressure (see diagram 7) instead of measuring blood pressure of the respondents (see diagram 8) and the distance from the elbow cuffs well (see diagram 9). In the last category were identified principles that respondents know for correct measurement of blood pressure (see diagram 10). Conclusion: Arterial hypertension is a very dangerous disease, it is important to have this disease, at least partially controlled by measuring the blood pressure. It is important that all hypertensives knew and adhered to the principles for measuring blood pressure.The result of this work is to evaluate the most common mistakes self-monitoring of blood pressure, hypertensive who have committed in home care.This output should be used to assess and prevent further errors in the measurement of blood pressure, for possible patient education nursing staff.
Blood presure measurement in LabVIEW
Čermák, Marek ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
The aim of this work is to design and create a product for automated measurement of blood pressure by auscultatory method by using a computer. Thesis contains a description of the blood pressure, also there are explained ways of its monitoring, basic rules for its measurement and the methods by which it is possible to measure blood pressure. In the practical part is described measuring system serving to measuring blood pressure by auscultatory method using a computer. There is also shown a design and realization of microphone preamplifier. The work also includes a description of a computer program created in LabVIEW, which is used to measure by using a previously described system. In the end is evaluated the accuracy of the whole meter.
Blood presure measurement in LabVIEW
Pelikán, Ondřej ; Štohanzlová, Petra (referee) ; Harabiš, Vratislav (advisor)
The main purpose of this semestral project is to design and realize a product that allows to acquire the Korotkoff’s sounds and measure blood pressure by using a computer. The paper gives a proposal of the preamplifier for acquisition of Korotkoff’s sounds, wiring of product and designed software for data acquisition. Document also contains theoretical informations about options of blood pressure measuring.
Measurement of the blood pressure using LabView
Slezák, Pavel ; Chmelař, Milan (referee) ; Kolář, Radim (advisor)
This thesis deals with the design of system for blood pressure measurement. The system consists of microphone, amplifier and real time acquisition program using LabView. For determining systolic and diastolic blood pressure origin and ending of Korotkov's sounds is used. The algorithm for this detection is based on bandpass filtering and thresholding also implemented in LabView. As a result of this work, the measured sounds are presented and whole system is described in detail. In conclusion advantages and disadvantages of method are resumed.
