Mitrengová, Jana ; Mézl, Martin (referee) ; Králík, Martin (advisor)
The thesis deals with the realization of methods for estimation of the respiratory curve from the ECG signal. The first part of the thesis deals with the anatomy and physiology of the respiratory and cardiovascular system. In this part of the thesis are also described ways of the breathing monitoring. The second part of the thesis is dedicated to the description of individual methods for the ECG derived respiration. The third part deals with the realization of selected methods, application of method algorithms on real data and comparison of resulting respiratory curves with the respiratory signals available from the PhysioNet database. In conclusion, the individual methods are compared with each other.

ECG and PPG derived respiration estimation
Chmela, Radek ; Smital, Lukáš (referee) ; Králík, Martin (advisor)
This work deals with the estimation of the respiratory curve from ECG and PPG signals. The first part deals with the description and monitoring of electrical activity of the heart, physiology and methodology of respiratory sensing and photoplethysmography. The second part deals with methods of extracting respiratory cycle information from ECG and PPG recordings. The third part deals with the algorithmic implementation and evaluation of individual procedures for estimating the breath curve from both of the above-mentioned signals on records from the web PhysioNet. In the last part, the algorithms are compared and evaluated.

The effect of the COVID 19 infection on the respiratory and cardiovascular system, physical stress during the course of the disease
Doležalová, Anna ; Heller, Jan (advisor) ; Šteffl, Michal (referee)
Title: Impact of the COVID 19 infection on the respiratory and cardiovascular system, physical strain during the course of the disease Aims: The primary aim of this thesis is to find and study the latest relevant findings regarding the impact of COVID 19 infection on the respiratory system, cardiovascular system and the effect of physical strain on the course of this disease. Subsequently, to write down a critical review on the topic. Methods: A literature review on the impact of COVID 19 infection on the respiratory system, the cardiovascular system and the effect of physical strain on the course of the disease. Results: The impact of the COVID 19 infection on the respiratory system is considerable. The disease can be asymptomatic or with only mild symptoms, typically shortness of breath and cough. The main manifestation of a developed infection is bilateral covid pneumonia, which progresses to ARDS in approximately 20-30% of hospitalized patients. The impact of the disease on the cardiovascular system is increasingly debated. Sources describe elevation of troponin in the serum, as an indicator of myocardial damage, in up to 12% of all cases. It can manifest as myocarditis, arrhythmias, myocardial infarction, cardiogenic shock or even heart failure. The infection of COVID 19 is a multisystem...

Gradually increasing maximum inspiratory resistance during respiratory muscle training and its effect on respiratory function in chronic tetraplegia
Šilhová, Vanda ; Laštůvková, Petra (advisor) ; Našincová, Zuzana (referee)
The theoretical part of the thesis describes basic mechanisms of spinal cord injuries, summarizes respiratory complications of spinal cord injuries and the use of respiratory physiotherapy with emphasis on breathing trainers. The practical part of the thesis focuses on the effect of 6 week long inspiratory muscle training using the Threshold IMT or Powerbreathe breathing trainer on respiratory functions in patients with chronic tetraplegia, as well as comparing the results of the study with available research exploring the same issue. The research included one experimental group consisting of 15 probands. All probands underwent measurement of spirometry parameters prior to the therapeutic intervention and again after six weeks of breathing training. A total of six respiratory parameters were evaluated (FVC, FEV1, PEF, PCF, MIP, MEP). From the results of the study, it can be concluded that breathing training showed positive effects on all of these parameters, but statistically significant difference was demonstrated only in the parameters evaluating the strength of the inspiratory (MIP) and expiratory (MEP) muscles.

Physiotherapy in people with multiple sclerosis with higher neurological disability
Knapová, Veronika ; Novotná, Klára (advisor) ; Suchá, Lucie (referee)
BACHELOR THESIS ABSTRACT Author: Veronika Knapová Supervizor: Mgr. Klára Novotná, Ph.D. Title: Physiotherapy in people with multiple sclerosis with higher neurological disability Abstract: The bachelor thesis deals with the possibilities of physiotherapy in patients with multiple sclerosis (MS) with severe disabilitiy focusing on postural and respiratory functions. The theoretical part gives a comprehensive overview of the problematics of this disease. Great emphasis is placed on the possibilities of rehabilitaion care in MS, especially in patients with severe neurological deficit and the importance of the interdisciplinary team. Furthermore, there is a chapter devoted to respiratory physiotherapy and basic terms in the postural system, on which procedures used in a practical part are focused. In the practical part I focus on the description of case reports of 4 patients with MS with severe neurological deficit according to the Expanded disability status scale 7.0 and more. Each patient underwent 6 individual home therapies. The therapies were focused mainly on influencing respiratory and postural functions. The results of these therapies were objectively evaluated using the following functional tests: Unsupported Sitting Endurance Test, Modified Functional Reach Test and Examination Of the Strenght Of...

Monitoring of lung function impairment by infectious disease COVID-19 using spirometry
Petrásková, Eva ; Kuchařová, Monika (advisor) ; Bernhauerová, Veronika (referee)
The thesis is focused on the comparison of functional examination of the patients lungs, before and after coronavirus disease 2019 (COVID-19), as well as on the comparison of physiological data for a individual person with measured values after the disease. The relationship between lung function and smoking, sex, age and time gap after COVID undergone was monitored. The screening was accomplished by spirometry in a pneumology surgery and the obtained data were processed in practical part of my thesis. The theoretical part of the diploma thesis describes the respiratory system and lungs functional testing. In addition, infectious disease COVID-19 is described herein. The aim of the thesis was to select suitable patients, who have suffered from the COVID-19 disease, but without other serious respiratory problems, make a measurements and statistically evaluate the correlation between the measured results. The experiment involved 66 people aged between 21-94, of which 43 were men and 23 women. It has been shown a predominantly negative effect of COVID-19 in the values of the examined indicators in spirometric measurements, similarly, the impairment was seen more in men than in women. The role of younger age has been proven in the better results of spirometric measurements. However, the differences in...

Power output and selected cardiorespiratory parameters in elite athletes during the third to fourth week after COVID-19 infection
Novák, Jan ; Nováková, Tereza (advisor) ; Heller, Jan (referee)
Title: Power output and selected cardiorespiratory parameters in elite athletes during the third to fourth week after COVID-19 infection Objectives: The aim of this thesis is to compare power output and selected cardiorespiratory parameters in elite athletes before and three to four weeks after COVID- 19 infection. Since the elite athletes undergo these health checks on a yearly basis, it is possible to compare the data before and immediately after the infection without difficulty. Methods: This thesis has a character of a quantitative research based on testing the outcomes with confirming or denying hypotheses. Out of the total of 64 elite athletes with the CPET data after the infection 17 athletes, fulfilling other criteria, were selected. I was provided with the data by Centrum sportovní medicíny z. s.. These values became the foundation for statistical hypotheses testing. Analysis of the data was done by means of a pair t-test in R software. Results: There were no significant differences in the majority of the spirometry parameters. Only the inspiration vital capacity was significantly higher (p = 0,004) after the COVID-19 infection in 14 athletes with 0,21±0,18 l improvement. There were significant differences in five of CPET parameters. Load in RCP was significantly lower (p = 0,011) in 13...
