Artificial aorta for activity demonstration of intraaortal baloon contrapulsation
Bičiště, Jan ; Rampl, Ivan (referee) ; Zeman, Václav (advisor)
This dissertation work describes design and construction of simulated aorta device intended to demonstrate performance of the intra-aortal balloon catheter (IAB), and to test reaction of the contra-pulsation pump during simulated cardiac output in conditions of tachycardia, bradycardia and arrhythmia. The major part of the device is transparent plastic tube. The pressure pulses (waves) are generated inside this plastic tube to simulate real cardiac output. These pressure pulses are generated by step motor with membrane. The step motor is controlled by programmable control system AMiNi-E. Individual pressure pulses simulate cardiac output in conditions of tachycardia, bradycardia and arrhythmia. Required simulated cardiac output is selected by control switches. Generated pressure pulses are read by pressure sensor and are transferred to the control system of the configuration computer. Read data can be displayed as graphs in program Microsoft Excel. The intra-aortal balloon catheter (IAB) is inserted inside the aorta and is connected with contra-pulsation pump which on pressure pulse is responding.

Selected technology monitoring in intesive care in a historical context
KNAJZLOVÁ, Petra
The diploma thesis presents the development of selected monitoring techniques of basic life functions in historical continuity. From the measured variables, this work includes measurements of cardiac activity, blood pressure, pulse, respiration and body temperature of the adults patients with intensice care in a historical context. This is a theoretical diploma thesis, which is divided into several chapters describing the history of nursing, a view of the monitoring in intesive care in the historical context to the presents. The first part of this historical work describes the beginnings of nursing. Its own origin and development, until now. The prestige of the nurse´s profession is formed by the society. In the leading positions in medicine previously dominated the men, in nursing care mainly women. A balanced relationship between a nurse and a doctor has been and is very important. The next part is devoted to the development of intensive care and the development of the role of the nurse in these departmenst. The history of intensive care has led to new partnership relationships between physician and nurse. There was an unfamiliar environment in which critical patients had to be cared for. This new role for the sister led to the increase of copetencies, there was a need to increase the education activity that focused on intensive care area. The view of urgent condition has changed over time. Already in the early sources, the urgent condition was described as a condition in which the health and life of the affected person is urgently threatened. These urgent conditions gave rise to the first beds for intensive care. Futher, the development of all monitoring techniques to date, servise of the monitoring technology. The negatives associated with monitoring technology are described too. The thesis will be used as a preview of changing nursing care in the context of changes in monitoring techniques of the intensive care.

Analysis of the influence of sports massage back to the heart rate for students of physical education PF JU
KLÍMOVÁ, Simona
The aim of this thesis is to prove whether a sporting massage of a back has an influence on the heart rate change. The analysis was carried out on female physical education students of PF JU, aged 20 23, specifically on ten of them chosen random, who agreed with the usage of measured data. The measurement was carried out in the lessons of Complex regeneration on the physical education and sport department of PF JU and the measurement was done by a digital arm pressure gauge type Tensoval duo control. The heart rate data were taken before the massage, during the massage, right after the massage and after five minutes from the massage. The results prove that heart rate decreased and changed only about 10 heartbeats maximum.

Využití raků jako bioindikátorů kvality vody
KUKLINA, Iryna
In recent decades, the ecological status of the freshwater crayfish has changed drastically from a sensitive indicator of an aquatic environment to a tolerant species that can survive in a wide range of unfavourable conditions. Despite all controversies on being or not being proper bioindicators, crayfish are a key species that plays a crucial role in the freshwater ecosystem. Regardless of whether certain crayfish possess a particular environmental sensitivity or not, all species can be used in biomonitoring investigations. The main objectives of the present thesis were development and implementation of system for continuous monitoring of water quality using crayfish as the bioindicator. Being less complex than vertebrates (e.g., fish), but being sufficiently complex compared to some other hard-shell freshwater invertebrates (e.g., mussels), crayfish present a useful biomonitoring object, which is easy to manipulate with, and which provides experimental data which is easy to obtain, analyse and interpret. The first part of this thesis is devoted to an evaluation of crayfish as suitable bioindicators. We showed that, when conducting the biomonitoring of metals in aquatic biota, crayfish have sufficient tissues for a bioaccumulation survey. For this purpose, we examined the gills, muscles and hepatopancreas. We confirmed that the hepatopancreas was the primary target for accumulation of most of the examined elements (i.e., cadmium, chromium, copper, nickel, zinc). For higher relevance, crayfish surveys were compared to fish samples collected from the same locations. The second part of this work particularly focused on water quality biomonitoring based on the evaluation of crayfish ethophysiological characteristics. We examined crayfish reactions to both chemical (i.e. chloramine, chlorides, nitrites) and natural odours (i.e., food, heterosexual conspecifics, predator, etc). This approach was shown to be simple yet at the same time, complex and efficient. Such monitoring technique is easily implemented and does not demand long, complicated analyses, since monitored parameters, locomotor and cardiac activity, are evaluated immediately in real time. However, one complication is related to the unpredictability of an animal's reactions. Because studied characteristics may often affect each other, they need to be carefully traced and interaction between measured characteristics needs to be eliminated. The usefulness of such biomonitoring is conditioned by a reliable combination of behaviour and physiology, which enables detection of complex animal responses to environmental changes. As reported in the third part, we submitted an application for a patent of the developed system, and described in the patent sensor will be protected as utility model. Moreover, other crustaceans with sufficient carapace size (e.g., shrimps, crabs, molluscs) can be successfully investigated using presented system. The only challenge is that living organism can clearly indicate disruption of ambient conditions, but cannot detect what it has caused. However, there are powerful analytical techniques now, developed exactly for accurate determination of various compounds. The heart rate is species- and conditions-specific, so it cannot be applied as unified measure for all crayfish species, while visual analysis of heartbeat primary curves can be useful for establishment of referent crayfish heart rate values at their different functional states. The final part of the thesis is devoted to this issue. In conclusion, the developed biomonitoring system was shown to be highly practical unit using noninvasive technique for investigation of crayfish reactions under model conditions, with the potential of further application at broader research and industrial arenas.
