The effect of emergency medical service arrival time on survival of cardiac arrest in the field due to cardiac causes
Chaloupková, Petra ; Knor, Jiří (advisor) ; Brizgalová, Nikola (referee)
The diploma thesis dealt with the influence of the emergency medical service arrival time onthe survival of cardiac arrest due to cardiac causes. In the research part of the work weworked with the data of the Emergency Medical Service (EMS) from Pardubice Region for the year 2022. Descriptive statistics, the Chi-square test of independence and Fisher exact test were used inthe thesis with hypothesis testing at a significance level of 0.05, i.e. 5 %. From the total number of 323 cases, in which sudden cardiac arrest occurred, data from 163individuals were selected. The time of EMS arrival at the place of the incident was investigated in connection with achieving ROSC or exitus lethalis. In Pardubice Region the most common EMS arrival time for OHCA was 6-10 minutes. At the same time, this is also an arrival time slot, in which the most patients (44.93 %) achieved ROSC. It therefore follows follows from this data that the arrival time of the EMS to the OHCA has an effect on survival. The thesis also looked at the factor of laic CPR before the arrival of the EMS, which could have an effect on survival in OHCA cases. During the observed period, laic CPR was provided to 67.48 % patients out of which only 27.27 % achieved ROSC. This indicates that the outcome of CPR is not affected by laic CPR. Last but...

Electromagnetic interference and pacemakers
Kulík, Jindřich ; Richter, Miloslav (referee) ; Havlíková, Marie (advisor)
This thesis deals with electromagnetic compatibility of implantable electro-medical devices using in cardiology. The main aim of this thesis is detection of the resistance of implantable pacemakers (PM) and implantable cardioverter defibrillators (ICD) to the electromagnetic interference. In the first part of this thesis, a function of the heart, which is necessary for understanding of PM and ICD operation, is described. The function and construction of PM and ICD is detailed in the theoretical part as well. The next part is focused on the electromagnetic compatibility. The next part is description of the measurement method and the experimental arrangement used for practical experiments with electromagnetic resistance of PM and ICD.

Design and implementation of TEM cell
Bednarský, Vojtěch ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
The purpose is to design and make a TEM cell, which may often be referred to in publications as a Crawford chamber, after the inventor. The operating frequency is specified from 100 kHz to 400 MHz and is suitable for a test device of maximum size (0,3(l) x 0,3(w) x 0,1(h)) meters. I will first describe the basic methods of electromagnetic susceptibility testing, and electromagnetic interference measurements, and then mention the issues and motivations for the fabrication of the closed TEM cell. Computer simulations were performed in the numerical computing software CST Microwave Studio. The calculated dimensions were used as a starting point for simulation. Dimensions from the simulation were used for the fabrication of the closed TEM cell, which showed similar results as the results of the simulations.

Integrated management system
Rucká, Marie ; Teš, Vasilij (referee) ; Fiala, Alois (advisor)
The thesis focuses on one particular organization and analyzes its options for introducing an integrated management system. The author takes a close look at the processes of that organization, and makes a list of all the important things that are related to the processes (including their limits and conditions) and that should be carefully considered when the directives and regulations of the organization are being made.
