The issue of permanent urinary catheter exchange in men - outpatient care vs. home health care
CAHOVÁ, Veronika
This bachelor's thesis addresses the issue of exchanging a permanent urinary catheter in men - outpatient care vs. home health care. The theoretical part of this work focuses on the catheterization process, proper nursing care of the urinary catheter, and also mentions the most common complications arising from catheter insertion. A significant portion also focuses on home care and education. The objective was to map the exchange of the permanent urinary catheter and to identify differences in the exchange process between a urological clinic and home care, and lastly, to compare patient experiences with both forms of exchange. A qualitative research method was used, employing semi-structured interviews. Four nurses from home care and four from a urological clinic were interviewed, as well as four patients from home care and four from the urological clinic. Three objectives were set, each associated with one research question. The research questions investigated specifics in catheter exchange and nursing care for the urinary catheter both in the urological clinic and in home care. The last research question examined the roles of nurses in this procedure. The research results show a difference in the thoroughness of nurses. Nurses from the urological clinic do not adhere to the proper guidelines during catheterization of the bladder. Patient education occurs in both the urological clinic and home care, but nurses from home care educate patients better and more frequently than nurses from urology. Education should focus more on catheter movement to prevent complications. Patients are satisfied with both forms of exchange, but it is clear that home care is not only more advantageous for the patients but also easier for hospitals. The output of the work is a basis for improving deficiencies in performance, but can also serve as motivation for expanding collaboration between hospitals and home care.

Determination of Blood Pressure
Plch, Miroslav ; Smital, Lukáš (referee) ; Čmiel, Vratislav (advisor)
The thesis includes a general introduction to monitoring and measurement of blood pressure of horses, the design of algorithms for pressure curve detection and the calculation of respiratory variabilities in mechanical ventilation under anaesthesia. The first two chapters focus on anatomy, on characteristics of blood flow and on vascular system. Then it deals with the measurement of blood pressure, monitoring of a horse under anaesthesia and it describes particular thermodynamic parameters. In the following part of the thesis, the methods of pressure curve detection are described. The last part contains the description of an algorithm designed for detection of pressure curve of horses in the environment of the program LabVIEW. The program calculates, displays and saves variabilities of systolic pressure, pulse volume, pressure amplitude, pulse frequency, peripheral resistance and vascular expansion from the detected values.

Conductive model of human tissue for electroporation purposes
Zelinková, Kateřina - Šarlota ; Cipín, Radoslav (referee) ; Novotná, Veronika (advisor)
This thesis solves the issue of the distribution of the high voltage pulse at the electroporation of the arget ablation zone. For futher examination of influence electroporation was necessary to first understand theoretically electrical charakter of cells and replace with basics eletrical circumferential elements (RLC). Based on this knowledge, theoretical prerequisites for experimental measurements were derived. Theoretical assumptions were then verified by experimental measurements. In the measurement, the assumptions found were confirmed, but significant performance losses were identified. A new catheter was designed to reduce the loss. Because the production of a new catheter is not economically disadvantageous, the properties of the new catheter were first tested using the simulation cloud environment SIMSCALE, where the heating of the heart tissue after the application of the electroporation pulse was monitored. Furthermore, the electroporation process was simulated in the FEMM program, where emphasis was placed on the propagation of cardiac tissue tension.

Determination of Blood Pressure Parameters for Ventilation Control during Anaestesia in Horses
Horský, Martin ; Provazník, Ivo (referee) ; Čmiel, Vratislav (advisor)
The present work deals with the issue of hemodynamic monitoring of blood pressure in horses during mechanical ventilation in anesthetized horses. Result of this work is an extension to the application Datex-Ohmeda S/5 Collect, which from the pressure curve provides values needed for optimal ventilation. Initial chapter provides a general physiologic introduction. It describes the definition of blood pressure, cardiac cycle and description of the pressure curve. It also deals with the hemodynamic parameters such as pulse pressure, stroke volume and their variabilities. In the second chapter is described methodology of measuring blood pressure in horses. Both, noninvasive and invasive methods are included. The third chapter analyzes fluctuations in blood pressure during ventilation. The last fourth chapter describes the implemented extension module which is designed to monitor hemodynamic parameters of the pressure curve.

Odběr spermatu pomocí katetru a jeho využití při výtěru štiky obecné (Esox lucius L.)
PLAŇANSKÝ, Tomáš
The aim of this diploma thesis is to compare quality of northern pike sperm collected by different methods. First method is collection of stripped sperm by abdominal massage of the belly. Second method is collection of stripped sperm with special catheter to eliminate sperm contamination by urine. The last method is collection of testicular sperm. Differently collected sperm was evaluated and compared its quality. The main observed parameters were sperm volume, spermatozoa concentration, spermatozoa motility and velocity and osmolality of seminal fluid. Sperm samples were used for eggs fertilization. In fertilized eggs, the fertility of eggs and larvae hatching rate were observed.
