Elaboration and testing of an user manual for the operation of the Haux Medicom transport baro-chamber intended for the treatment of decompression accidents associated with diving, verification of the transport of the affected person and its transfer for subsequent treatment
KARVÁNEK, Jakub
The aim of this thesis is to develop and test a user manual for the operation of the Haux Medicom mobile transport hyperbaric chamber designed for the treatment of decompression accidents associated with diving, as well as the verification of the transport of the affected person in the barochamber, following connection to the stable treatment barochamber and the transfer of the affected diver for subsequent complex treatment. The Haux Medicom barochamber is used by members of the diving group of the South Bohemia Fire Rescue Corps to ensure safety during rescue operations and underwater training. The Baro Chamber is used to mitigate the consequences of diving accidents and especially to treat decompression sickness. This treatment is based on the principle of recompression therapy, where the pressure in the hyperbaric chamber is gradually increased up to the prescribed therapeutic pressure, followed by a slow decompression in combination with breathing 100% oxygen. Operating this chamber requires a lot of experience and regular practice. One of the aims of this thesis is to develop a simple, clear and functional user manual to assist the person operating the barochamber. This manual has been developed and its functionality has been tested by members of the diving group and other professionals involved in this field. The second task was to verify the transport of the diver in the barochamber and his subsequent transfer to a stable hyperbaric chamber to provide further treatment. In order to accomplish this task, a tactical drill was organized by the diving group of the Fire Rescue Corps in cooperation with the Kladno Regional Hospital and this unique, never before realized attempt was successfully carried out.

Physiological differences and potential risks while scuba diving and freediving
Flodr, Tomáš ; Fiala, Miloš (advisor) ; Hošek, Václav (referee)
Title: Physiological differences and potential risks while scuba diving and freediving Objectives: Goal of this study was to prove, whether freedive performed after finished dive using self-contained underwater breathing apparatus, may potentially increase the risk of decompression sickness and afterall put together appropriate principals and guidance for safe combining of both scuba diving and freediving on the same day. Methods: This study used research of local and foreign sources that covered freediving and diving using self-contained underwater breathing apparatus issues. Casual research was also conducted involving 34 participants, all certified self-contained underwater breathing apparatus divers experienced in combining freediving and scuba diving on the same day. Results: Based on the research has been found that a freedive performed after dive using self-contained underwater breathing apparatus may under certain circumstances increase the risk of decompression sickness. Conservative principals and recommendations for safe combining of scuba diving and freediving on the same day were established. Results of this study will be provided to local and foreign diving communities. Keywords: Scuba diving, decompression sickness, nitogen load, freediving, risks

Risks occurring in connection with effects of the abnormal physical pressure on the human organism in the specific environment
ŠEBERKA, Jan
With extending possibilities the present population has available, also a number of injuries occurring in extreme environments for example under the water level or in the above the sea level higher than 2400 meters is expected to grow. This bachelor thesis called Risks occurring in connection with effects of the abnormal physical pressure on the human organism in the specific environment summarizes in the contents the risks and diseases which may occur under the changed conditions. The target of this thesis was to map the knowledge of the differential diagnostic procedures and of the following adequate therapy of the states caused by abnormal physical pressure of the employees of the medical rescue service and employees of the mountain service in Liberec region and in the surroundings. In the introduction of the theoretical part, basic physical information is presented. For example how the human organism compensates the normal, increased or decreased physical pressure. Moreover the theoretical part deals with the particular diseases occurring as a consequence of the increased or decreased pressure in the environment. For each of them the name of the disease is stated, its characteristics, patho- physiology, clinical symptoms and the respective therapy. Also the recompression treatment in the decompression chamber and location of these decompression chambers in the Czech Republic is stated here. It follows from the thesis that more than one half of the medical and mountain rescuer are well orientated in this issue. However, we find here the questions in which they were not sure. It follows from the research which is the subject of the practical part of the bachelor thesis that the mountain rescuers have a more extensive knowledge in the field of the alpine medicine than the medical rescuers. Medical rescuers, however, have shown better knowledge in the diving accidents. It follows from the thesis that the incidence of these kinds of injuries is not high, however, this fact should not lead the medical and mountain rescuers to the opinion that they do not need further education in the given branch. On the contrary, it would be suitable to organize a seminar on this topic and to increase in this way the level of knowledge of the members of the medical rescue service and members of the mountain service in the field of the alpine and diving medicine.
