Obstructive sleep apnea detection using polysomnography
Smrčková, Markéta ; Mézl, Martin (referee) ; Králík, Martin (advisor)
This thesis attempts to find an alternative method for automatic detection of sleep apnea using polysomnographic data. The first part is focused on introduction to lungs anatomy and physiology of breathing, sleeping and cardiac system. The second part describes the process of sleep examination and particular components of polysomnographic data. The third part is focused on realization of specific method for sleep apnoea detection, application on real data and results evalutation.

Heart rate variability analysis from sleep ECG
Lepková, Kamila ; Kozumplík, Jiří (referee) ; Králík, Martin (advisor)
This bachelor thesis deals with an analysis of heart rate variability from sleep ECG. The thesis is divided into two parts, the first one is theoretical part and describes the physiology of heart and respiratory system, ECG curve, sleeping phases, apnea, and above all analysis of heart rate variability of ECG. In the practical part, using MATLAB software, was developed an algorithm of the analysis. The algorithm was tested on real signals from a publicly accessible database. The difference between the physiological ECG and the ECG with apnea is statistically evaluated using sing parameters from the time and frequency domain. Kruskal-Wallis statistic test confirms that there is a significant difference between the physiological signal and the apnea signal.

Infant Movement Monitor
Zahradníčková, Ludmila ; Chmelař, Milan (referee) ; Sekora, Jiří (advisor)
Movement monitor is a detection device for monitoring the frequency of breathing of newborns and infants. It is usually indicated to children under the one year as a support to reduce the risk associated with sleep apnoea and Sudden Death Syndrome. The theoretical part of this bachelor thesis discusses the physiology of respiration, respiratory disorders, methods of monitoring and treatment. The aim of the technical part is to design own monitoring device for detecting and evaluating the frequency of breathing. It includes a block diagram and a wiring scheme of device and a flow chart of program, which is implemented by a microcontroller.

Detection of sleep apnea from polysomnographic signals
Vecheta, Miroslav ; Potočňák, Tomáš (referee) ; Kozumplík, Jiří (advisor)
This thesis deals with the detection of sleep apnea using polysomnographic data and attempt to find a possible alternative and simpler method of this detection. The thesis consists of three parts: The first part is important for introduction to the lungs anatomy and the physiology of breathing and the sleep phisiology. The second part deals with the ways of testing sleep apnea. The third part then continues with implementation of alternative methods of testing in Matlab software. The final program calculates the breathing curve from ECG data. The curve is important for the final detection of sleep apnea.

Sleep apnea detection
Hastík, Matěj ; Janoušek, Oto (referee) ; Ronzhina, Marina (advisor)
This master‘s thesis deals with a detailed description of sleep apnea and methods of detection of sleep apnea. The first part of the work is focused on the physiology of sleep, sleep apnea itself, its distribution, symptoms, risk factors and treatment. The next part of the work deals with polysomnographic examination and methods for analysis of polysomnographic data. The last part is devoted to the procedure design for detecting sleep apnea by using only one kind of signal and by using more kinds of signals, implementation of these proposals, their testing on real data, evaluating the detection performance and comparing the results with data available in the literature.

Multidisciplinary collaboration and the role nurse in the care of patients with sleep apnea syndrome
MATĚJKOVÁ, Naděžda
Sleep belongs to basic human needs and it is not only its length but also its quality that matters. Sleep disorders cause a lot of illnesses and therefore it is important to examine them and to treat them What are the most common symptoms of the ill state? somnolence, i. e. sleepiness during the day, disturbed or interrupted night sleep, or its lack. All these symptoms are necessary to be focused on. Sleep disorders are classified according to the International Classification of Sleep disorders ICSD 3 of 2014. This work deals with the problem theoretically. The first aim of this work was clarifying basic concepts of the problem - the syndrome called sleep apnoea. The next one was focusing on the multidisciplinary approach to the patients with this syndrome, so typical and very important. The main focus is upon the sleep apnoea syndrome, the patients suffering from it and multidisciplinary collaboration during their treatment. The main focus is upon the sleep apnoea syndrome, the patients suffering from it and multidisciplinary collaboration during their treatment. After having studied both Czech and foreign sources thouroughly, the general task of this work became summarising all the results of the research in one study . One part of this work is devoted to the detailed medical examination of sleep and its disorders. It describes polygraphic and polysomnographic tests, the procedure of the testing, the interpretation of the results, also the methods of the treatment with positive airway pressure during the sleep currently considered to be the most effective method of treatment of the adult and child patients. Next part of the work which focuses on multidisciplinary approach to the patients suffering from sleep apnoea describes surgical possibilities of the treatment within otolaryngology and methods of treatment within pulmanology. The last part of the work concentrates on the work of the nurse. It deals with the competences and further education of the nurses working for sleep laboratories. Prominent medical journals have become the key sources of information and the latest knowledge of sleep medicine.
