Continuous measurement of blood pressure
Kopčil, Petr ; Chmelař, Milan (referee) ; Nováková, Zuzana (advisor)
This paper deals with the physiology of cardiovascular system, explains elementary principles related to blood flow physiology and describes some basic mechanisms for regulation and blood pressure measurement. The paper also includes a description of the medical device, known as the Finometer (FMS, Netherlands), for continuous non-invasive blood pressure measurement and suggests a way to data export from this device to a text file. It introduces user friendly application to manage recorded data written in MATLAB. There is a statistical test to assess the difference between two statistical data files in the last chapter of this paper which includes a comparison our results with studies made in Czech Republic and other countries too.

Polygraphic measurement of stress
Faltýnková, Květoslava ; Kolář, Radim (referee) ; Bubník, Karel (advisor)
This work deals with polygraphic measurement of stress. The paper describes the physiological manifestations of stress induced as a result of false answers to the question and ways to measure these phenomena. It focuses mainly on changes in heart rate, blood pressure, respiration and skin resistance. It is designed to work in the block diagram of polygraph, described the course of measurement and evaluation. The work is also mention of lie detection using EEG.

Measurement of blood pressure and influence of physical load
Vymazal, Bronislav ; Chmelař, Milan (referee) ; Kolářová, Jana (advisor)
Bachelor's thesis is focused on influence assessment of physical load on systolic and diastolic blood pressure. It is analyzed cardiovascular system of human being and an influence of his function on blood pressure. There are mentioned methods of blood pressure monitoring, their physical principle, advantages and disadvantages in the text. The author suggested measuring protocol and methods of statistical processing and evaluation of results.

Evaluation of pulse wave velocity in the human body
Mezuláníková, Radka ; Viščor,, Ivo (referee) ; Jurák, Pavel (advisor)
This Mater's thesis deals with the evaluation of pulse wave velocity using multi-channel whole-body impedance cardiography. Data were taken from the group of healthy volunteers whose impedance changes were measured during rest, respiratory maneuvers, tilt and stress exercise. The result of this measurement are values of peaks of pulse wave time shifts towards R-wave. The velocity values towards the thorax electrodes were recalculated on the basis of knowledge about the pulse wave time shifts and the distances from the heart to the scanned locations, which were measured using the arterial segment's lengths.

Design of Blood Pressure Monitor
Běťáková, Vendula ; Řezníček, Svatopluk (referee) ; Fridrichová, Eva (advisor)
The goal of this bachelor thesis is a proposal design of blood pressure monitor, which should respect the functional requirements and conceptualize the technical and aesthetic aspects. The work includes a study of the current market situation and development of new technologies in the field. The proposal deals with an ergonomic design and issues.

Monitoring of blood pressure and heart activity via ECG in prehospital urgent care
VRÁNOVÁ, Anna
The topic of this thesis is monitoring of blood pressure and heart activity via ECG in prehospital emergency care. So the thesis deals with a necessary part of a patient´s examination that precedes effective treatment. In the theoretical part the prehospital emergency care is defined and the emergency medical service, which provides this care, is characterized. Anatomy and physiology of heart is outlined there. Also blood pressure and its measurement is discussed there. Electrocardiography is described and information needed to basic orientation in ECG recording is introduced. The practical part was carried out using mixed methods research. The first method was a quantitative research in the form of a standardized anonymous questionnaire. Employees of the Emergency Medical Service of the South Bohemia Region who work as paramedics became the respondents of this questionnaire. The qualitative research strategy consisted in observation of paramedics when they were monitoring blood pressure and heart activity via ECG in the prehospital emergency care. The aims of the research part were these: mapping of states and situations that lead paramedics to monitor patient´s blood pressure and heart activity, description of different methods of blood pressure and heart activity monitoring and finding the paramedics´ experience with available apparatuses. The last aim was a detailed introduction to monitoring of blood pressure and heart activity via ECG. The results show the following information. Paramedics measure every or nearly every patient´s blood preasure. They begin to monitor heart activity via ECG when the patient suffers from chest pain, is unconcsious, when there is a risk of arrhythmias or when the patient is circulatory unstable. Auscultatory method mediated via aneroid sphygmomanometer is the most frequent way of blood pressure monitoring in prehospital emergency care. Paramedics are satisfied with apparatuses and tools used to blood pressure and heart activity monitoring. All the acquired knowledge serves to detailed introduction to the issue which a paramedic meets in his or her everyday work and must have full control of it.
