Benko, Michal ; Strejcová, Barbora (advisor) ; Bunc, Václav (referee)
Title: The effect of sauna on the changes of blood pressure Objectives: The aim of this study was the measure of the physiological range (blood pressure, heart rate, blood oxygen saturation) of two selected groups of people within the sauna cycle, assess changes and compare the results of individual probands and groups. Methods: This thesis is conducted as an experimental study. This is a quantitative method, in that will be at first established hypotheses and then evaluated on the basis of the obtained results. The independent variable in this research is the sauna and dependent variables are blood pressure, heart rate and blood oxygen saturation. Results: Blood pressure values were at employee of sauna lower than at other probands, thereby was confirmed hypothesis, but expected significant differences between the measured values of each group were absent. At the same time there was a further confirmation of the hypothesis concerning heart rate, which was increased at all probands. The last confirmed hypothesis related to the blood oxygen saturation and its reduce after the sauna. It could be said that all the defined hypotheses were confirmed. Keywords: sauna, blood pressure, heart rate, blood oxygen saturation, cardiovascular system

Pazderová, Monika ; Matoulek, Martin (advisor) ; Štulc, Tomáš (referee)
Author's first name and surname: Bc. Monika Pazderová Supervisor of the thesis: MUDr. Martin Matoulek, Ph.D. Thesis title: The influence of the physical activity on high blood pressure in patients with obesity or metabolic syndrome Workplace: 3rd Medical Department, 1st Faculty of Medicine, Charles University and General Teaching Hospital in Prague and Health rehabilitation centre VŠTJ MEDICINA Prague Year of thesis defence: 2012 ABSTRACT Nowadays the metabolic syndrome belongs worldwide to the most widespread diseases. The joint occurrence of diabetes, obesity and hypertension has been known for a long time. Also nowadays many doctors consider obesity a typical risk factor for diabetes or hypertension. Generally it is true: the higher BMI the higher likelihood of hypertension occurrence. Hypertension is a risk factor for atherosclerosis which is a cardiovascular disease. Nowadays the high blood pressure belongs to the most common health disorders of populations in both developing and advanced industrialized countries. The complications of hypertension are an important cause of sickness rate, invalidity and death. The occurrence of high blood pressure increases with age and is also dependent on the gender. The average levels of systolic pressure increase with age. On the other hand, the average levels of...

The role of adrenergic system in genetic hypertension
Loučková, Anna ; Kadlecová, Michaela (advisor) ; Husková, Zuzana (referee)
The adrenergic system plays an important role in the regulation of blood pressure. In the spontaneously hypertensive rat, the most studied model of essential hypertension, many components of the adrenergic system are altered. Changes in expression level of any catecholamine biosynthetic enzymes or any adrenergic receptor subtypes could be one of the causes of hypertension development. In this work, the expression of adrenergic system genes was measured in adrenal gland, renal cortex and renal medulla of the spontaneously hypertensive (SHR), Wistar-Kyoto and Brown Norway rats at the age of thirteen weeks. In adrenal gland of SHR, all four catecholamine biosynthetic enzymes (tyrosine hydroxylase, DOPA decarboxylase, dopamine β-hydroxylase and phenylethanolamine-N- methyltransferase) and almost all subtypes of adrenergic receptors (with the exception of Adra1a and Adra1d) were underexpressed. This generally decreased expression in adrenal gland of SHR suggests that at least a part of regulation of adrenergic system gene expression is common. The mechanism of this downregulation in SHR could be a negative feedback through adrenergic receptors stimulated by high plasma noradrenaline concentration. In the kidney of SHR, there were no differences in the expression of most of adrenergic receptor subtypes with the...

L-serine induced effects on blood pressure in normotensive and hypertensive rats: the influence of anesthesia
Bencze, Michal ; Zicha, Josef (advisor) ; Husková, Zuzana (referee)
Anesthetics cause profound alterations in respiratory and cardiovascular systems. Our experiments demonstrated that different anesthetics caused different changes in blood pressure regulating components. The role of particular BP regulating systems was disclosed by their selective inhibition - sympathetic nervous system blocked by pentolinium (peripheral ganglionic blockade), renin-angiotensin system by captopril (angiotensin converting enzyme blocker) and nitric oxide production by L-NAME (nitric oxide synthase blocker). Components of blood pressure regulating mechanisms in conscious normotensive Wistar rats and spontaneously hypertensive rats were compared with four different groups of anesthetized rats by pentobarbital, ketamine-xylazine, chloralose-urethane and isoflurane. Each anesthesia caused different hemodynamic changes. If hemodynamic conditions should be similar to conscious rats, the most suitable anesthetic is pentobarbital. L-serine-induced effects represent endothelium-derived hyperpolarizing factor (EDHF)-mediated response, which is a type of endothelium-dependent regulation of vascular tone, independent of nitric oxide and prostacyclin production. Pronounced L-serine effects on blood pressure were shown in NO-deficient type of hypertension. Our study demonstrated its pronounced effects in...

Possibilities of influencing blood pressure in spinal cord injury patients during verticalization
Věchetová, Tereza ; Schreier, Bronislav (advisor) ; Slabý, Kryštof (referee)
Orthostatic hypotension is a common problem for individuals with spinal cord lesions, especially in the acute period after spinal cord injury. The first part of this study deals with the theoretical analysis of the pathophysiology of cardiovascular control after spinal cord injury, the definition of orthostatic hypotension and its inclusion within the classification of the syncopal conditions. An important part of the theoretical part is the management of orthostatic hypotension, which brings non-pharmacological therapeutic approaches, and marginally pharmacology, to decrease the severity of this condition. The experimental part focuses on testing of a group of probands with spinal cord injury (11 quadriplegics) on two different types of tilt tables according to the same protocol. The first tilt table is a standard; the second one is Erigo, tilt table with integrated robotic mechanism, which moves the legs to simulate walking. The parameters, such as blood pressure, heart rate, oxygen saturation, and the occurrence and severity of pre-synkopal symptoms, were compared. The study is based on the assumption that passive leg movement, which is mediated by the Erigo, will maintain venous return, cardiac output, and a significant drop in blood pressure and development of orthostatic hypotension,...

Evaluation of results using different methods of experimental measuring of blood pressure amongst students of the First Faculty of Medicine of the Charles University
Sova, Jan ; Kymplová, Jaroslava (advisor) ; Jirsa, Jan (referee)
During the projects from biophysics of freshman students of the Faculty of Medicine the pressure measurement is run by several different methods; palpation, auscultatory and digital method. Students are learning to record the measurement in a systematic way, and they are learning to compare the results of every method to each other. The measurement of systolic and diastolic pressure are dependent on each other of course, as well they are dependent on the set of biometric and other information that is well available in healthy students (sex, height, weight, physical strain etc.). The aim of the thesis is to compare the results acquired by the methods of measurement mentioned above, related to the accuracy of the scattering of the measurement and related to the anticipated standard values of healthy individuals. The basis of the thesis is going to be project and creation of the regression model for the levels of systolic/diastolic pressure measured out that is dependent on biometric data along with the testing of statistical importance of parametres through the procedure of multifactorial ANOVA for the repeated measurement. The result will aim to show both advantages and disadvantages of different methods of the pressure measurement during accordingly varying conditions of experiments. The thesis...

High normal pressure and hypertension of children and adolescents
KRÁLOVÁ, Kateřina
In children and adolescents, high normal blood pressure is often present. People with high normal blood pressure show a short time prerequisite to the formation of arterial hypertension. Hypertension occurs most often in children as asymptomatic. Increased blood pressure in children is most often discovered during preventive examinations by a general practitioner for children and adolescents. This thesis contains information about the anatomy and physiology of the cardiovascular system, a blood pressure measurement sister, evaluation of blood pressure, high normal pressure, high blood pressure in children, the role of nurses in primary care pediatricians in the area of communication and education, and treatment of high normal pressure and hypertension. Objectives The first goal was to explore how children adhere regime measures for the prevention of high normal pressure and hypertension. It used this research question: How children adhere regime measures for the prevention of high normal pressure and hypertension? The second objective was to determine the role of nurses in the care of children with high normal pressure and hypertension. The second research question is: What is the role of the nurses in taking care of children with a normal high pressure and hypertension? Methods used In the research part of the thesis, we used the method of qualitative research, questioning method and technique-depth interviews. The interviews were recorded on a Dictaphone and then transcribed literally. Four sisters and three mothers did not wish to be recorded, so they were interviewed at polling literally written on paper. For research, two research files were created. The first sample consisted of six nurses, who were working in GP surgery for children and adolescents in the South Region. Second survey consisted of six people selected from among parents of children with high normal pressure and hypertension, also from South Bohemia. Results The transcribed interviews were investigated by open coding method, pencil and paper. Resulted in 9 categories: Cardiovascular disease, role of the nurse, pressure measurement, blood pressure, hypertension, pressure measurement, recommendation, Lifestyle, Leisure. Individual categories were assigned to subcategories, which are encoded core data. Conclusion The first research confirms nurses working in a pediatrician's office for children and adolescents, the most common cardiovascular disease in the general hypertension. They argue that the role of nurses in primary care pediatricians is properly measure blood pressure and make the education of children and parents in the area. The respondents concurred in the principles of how to properly measure blood pressure measurement are available for at least three cuff sizes. Informants have basic information about high normal pressure and hypertension, and said that, in the offices of primary care pediatricians to conduct checks blood pressure of preventive examinations or troubled child. Informants reported that blood pressure control and education on blood pressure occurs, but in the second research study showed that children and adolescents do not comply with the recommended recommendations in this area, perhaps because they are less motivated. Neither sister nor the parents have not mentioned, they would receive educational aids such as brochures and sample menus.The second research showed that parents most often found elevated blood pressure in primary care pediatricians, either for reasons of preventive examinations or difficulty a child. On the control measurements came at least three times. Respondents agreed on the recommendations they received in the office GPCY such as reducing the weight of the child, regular physical activity, restriction of salt and proper diet the child, but not all children and adolescents comply with these recommendations. The research results will be provided to the journal Pediatrics practice.

Nursing procedures in taking blood pressure
SEDLÁKOVÁ, Tereza
By blood pressure is meant lateral pressure or the side pressure of a blood column on the side of a vessel. The pressure is created thanks to the action of heart as a blood pump. This pressure is not the same in different parts of the bloodstream. By the blood pressure is meant the arterial pressure or pressure in the artery, so the pressure in big blood vessels. The highest values are reached in the expulsion phase of the heart action, which is called systole. The lowest values are reached in the phase of filling heart chambers, which is called diastole. The sole nursing procedures required in the process of taking a blood pressure reading are many and all must be followed. This thesis is composed of a theoretical part and practical part. Introduction to the theoretical part is composed of the main terminology from the physiology of blood pressure. In the theoretical part we follow with division on hypotension and hypertension, which are the most common diseases related to blood pressure, with diagnosis and recommendation for treatment. This thesis also offers information about measuring blood pressure by the invasive and the non-invasive method. The theoretical part is focused on the importance of the nurse in the process of measuring blood pressure with emphasis on her knowledge and practical skills.
