Abstract

Many pathogenic micro-organisms are likely to attack passengers of cruise ships and other vessels or travel between continents as a peculiar type of a “stowaway”. The epidemiological tests conducted since 1987 with regard to watercraft led to the coining of a term known as the Sick Boat Syndrome (SBS). The main illnesses encountered on watercraft include gastrointestinal diseases (foodborne) and Legionellosis. Additionally, the ventilation and airconditioning systems of old commercial ships (the so-called Tramps) constitute a real technical challenge. Conditioned air (with removed undesired odour and micro-organisms) should constitute ca. 25% of circulating air. In practice this situation is not typical for vessels of this class. Unclean air poses a real hazard for the crew.

Abstract

The most common question that arose in the course of the analysis of the data concerned with the number of diving accidents in recreational diving as compared with the authors’ own experiences working with military divers was why the number of accidents in recreational diving is substantially higher than that obtained in military diving. The comparison of factors having a direct effect on diving safety, the scope of depths reached, the manner of conducting decompression and divers’ problems reported after diving completion allow to explain the reasons behind the common incidents occurring among recreational divers. The factors which had a very significant impact on safety level included diving frequency, adaptation to higher pressure conditions and overestimation of one’s skills in undertaking challenges.

Abstract

When working in chemical or biological environments, contamination is an extremely dangerous issue for the rescue services of the fire department, police and the army.

Modern protective overalls worn by fire fighters or dry “Viking” diving suits made from neoprene or nylon covered with polyurethane, have been proven to ensure sufficient protection. However, once the contaminated area is left, there is a need to perform decontamination of the external and internal surfaces of the protective overalls; in order to ensure the clothing continues to offer a high level of comfort and to retain the durability of said protective clothing, it is of course also necessary to perform a drying procedure.

Moreover, there is a risk of a transfer of pathogenic micro-organisms between persons utilising the same protective clothes, particularly in the case of expensive specialist suits. Micro-organisms which may potentially spread through clothing include intestinal bacteria, such as: Salmonella, Shigella, Campylobacter, E. coli (including E. coli O157), C. difficile, viruses inducing infections of the upper respiratory tract and alimentary tract (noraviruses, rotaviruses, adeno and astroviruses). The risk of infection also involves the presence of the flu viruses, herpesviruses and pathogens transferred through skin, such as S. aureus (including MRSA), yeast-like fungi (Candida albicans), fungal strains inducing Tinea pedis and Tinea corporis [1]. Pathogenic micro-organisms can easily transfer from fabric surface onto the body of a person wearing protective clothing.

From the numerous available techniques of decontamination of surfaces, equipment and protective clothing we propose to use for this purpose gaseous hydrogen peroxide (H2O2), a very effective biocidal agent. In field conditions, typical for the activities of rescue crews of the fire department, police and army we assume utilisation of a portable decontamination chamber enabling performance of a complete decontamination process.

The process lasting approximately 3 hours encompasses 3 phases:

• Drying phase;

• Decontamination with gaseous hydrogen peroxide;

• Catalytic combustion phase of hydrogen peroxide residues to a level safe for the environment.

The integrated humidity and H2O2 level sensors ensure automatic control of the entire process and the unique distribution system of gaseous H2O2 secures full accessibility of the biocidal agent to the external surface of protective clothing as well as its interior. Moreover, the container allows for the conduction of the complete decontamination of the rescue equipment, night vision devices, binoculars, field telephones, radio stations, etc. Upon decontamination cycle completion, we obtain a completely dried suit which can be safely used by another crew member.

Abstract

The purpose of the study was to determine the effect of composition of various breathing mixes on physical capacity of rats swimming in hyperbaric conditions. The said effect was determined on the basis of results of a swim test performed in a pressure chamber. The study was performed with the use of atmospheric air, a mixture of nitrogen and oxygen (N2/O2) at a ratio of 89.5/10 and 92/7.5, as well as a mixture of argon and oxygen at a ratio of 79.5/20 (Ar/O2). The tests were conducted at a pressure range between 0-4 atm. The results suggest that the physical capacity of the tested animals decreased along with pressure increase regardless of the breathing mix used. Due to the fact that the burdening of rats with physical effort in hyperbaric conditions intensifies the adverse effects of components of breathing mixes on their performance, it seems appropriate to continue the study of physiological responses to breathing mixtures of various compositions in human body subjected to physical effort while under water.

Abstract

Strong wind, low temperature, intense current and poor visibility under water are the most common stress inducing factors in individuals practising water sports. Stress is a state of agitation, which can be caused both by external and internal factors. Its objective is to mobilise one’s physical and psychological capabilities, thus it is a favourable reaction especially in crisis situations when such full mobilisation enables one to cope. Psychological stress is usually evoked by the occurrence of an atypical situation, exceeding one’s handling capacity. It can be induced by seeing real or imagined danger in the surroundings, as well as by external pressure related to a task interpreted as too difficult or exceeding one’s capabilities. Internal pressure appears when a person feels insecure in a given situation, when they cannot solve a problem or they feel discomfort due to their inability to meet the expectations of others, for instance, to perform a particular dive, or because of the money spent on this purpose or the invested time. Physical stress is usually an organism’s response to the environmental impacts. This article presents and discusses factors which have an effect on stress intensification, as well as providing a characterisation of selected psychological and medical theories of stress.

Abstract

Pathogenic micro-organisms can easily transfer from the surface of a diver’s skin onto the surfaces of a protective suit. A long-term stay in a hyperbaric chamber during a saturation dive increases the risk of infection if in the chamber there is even a single carrier of disease-causing pathogens.

The conducted research has confirmed that the diving equipment located in Diving Centres is a place of many different bacteria and fungi, including pathogenic ones. The vast majority of microbes found on the surfaces of wetsuits, etc. are commensals (with some being opportunistic organisms). This fact allows us to realise that the surfaces of diving equipment are an excellent “transmission route” for various dermatoses and other diseases. In order to reduce the risk of infection the diving equipment used by various people should be subject to the process of decontamination. The authors recommend decontamination with the use of gaseous hydrogen peroxide which does not cause damage to equipment.

Abstract

The aim of the article is to conduct a literature review in relation to the psychological aspects of diving. The acquired knowledge can currently be qualified as belonging to various branches of applied psychology, as well as underwater medicine, sports medicine, psychiatry and psychotherapy. The literature on this subject matter raises two main issues of the psychological perspective: the degree of psychological adaptation of an individual to the underwater environment, and the psychophysical condition of a man involved in a specific type of diving and the resulting skills/competences to perform underwater tasks. The article presents selected reports from around the world related to diving psychology resulting from the applied structure/classification of psychological theories, explaining various mechanisms of psychological functioning underwater. The paper presents studies from the perspective of psychodynamics, psychology of health/stress, psychology of individual differences and personality. The main conclusions indicate that in addition to the main problem of an optimal/lack of adaptation of humans to the underwater environment, there is insufficient psychological knowledge (including Polish reports) in the area of personality differences between various types of divers, their social functioning, mental health and psychoeducation with regard to underwater exposures.

Abstract

Hyperbaric oxygen therapy (HBOT) is found among the interests of researchers who seek new methods of treatment of diseases of the nervous system. An increase of the partial pressure of oxygen in arterial blood within the appropriate range leads to numerous changes in the cells of the brain tissue. In this paper we analyse the results of selected articles describing HBOT used on pathologies of the nervous system such as stroke, autism, multiple sclerosis and cerebral palsy as well as in the course of research on animal models. The results are promising, although some studies struggled with numerous methodological problems and differences in the applied protocols, which resulted in conflicting results in individual interventions. In consequence, the need for further studies in randomised control trials and determination of the protocol by an international group of researchers dedicated to the use of HBOT was emphasised.
