Book Description
Pratiquée depuis des millénaires par les ama coréennes et japonaises, puis par les pêcheurs de perles et d'éponges de la Méditerranée, la plongée en apnée est devenue un sport de loisir. Mais les contraintes exercées sur le corps par le milieu aquatique - la pression hydrostatique en particulier peuvent retentir sur les fonctions physiologiques et engendrer des accidents. Les origines et l'évolution de la pratique de la plongée en apnée à travers le monde et le temps sont retracées dans un premier chapitre introductif. La physiologie de l'homme immergé (effets physiques, effets morphologiques, transferts sanguins, etc.), les perturbations des fonctions respiratoires et cardio-circulatoires sont ensuite longuement développées, ainsi que les effets de l'entraînement sur les performances en durée et en profondeur. Un long exposé est dévolu à la plongée sportive en apnée, à l'étude des records, et en particulier aux records de profondeur. Le dernier chapitre est consacré aux divers incidents et accidents (dangers du tuba, hypercapnie lente, gastralgies, pertes de connaissance anoxiques, accidents de décompression, etc.) et à leur prévention ; l'aptitude médicale à la plongée en apnée fait l'objet d'un long développement. Cette étude détaillée de la physiologie de la plongée en apnée permet de répondre à de nombreuses questions, telles que la durée de l'apnée volontaire et les facteurs respiratoires qui la limitent, la profondeur maximale de plongée et ses risques, de mieux comprendre la pathologie spécifique de ce sport et de tenter de diminuer par des mesures simples de prévention le nombre des accidents. Ces données constituent des références précieuses pour tous ceux qui sont concernés : moniteurs de plongée, médecins du sport, médecins des fédérations, organismes ou institutions faisant appel à des plongeurs professionnels.

Book Description
This book is not a conventional review of diving physiology. The coverage of the literature has been selective rather than en compassing, the emphasis has been on field studies rather than laboratory investigations, and the dive responses described are often discussed from the perspective of some of the flaws or weaknesses in the conclusions. Some of these points are of more historical interest to note how our concepts have evolved as we learn more about behavior and responses to natural diving in contrast to forced submersions in the laboratory. As a result there is a degree of evaluation of some experiments on my part that may seem obvious or controversial to the specialist. I have followed this planat times in order to aid the reader, who I hope is often an untergraduate or graduate stu dent, the nonspecialist, and the layman, in appreciating to some degree the level of dissatisfaction or skepticism about certain areas of research in diving physiology. In view of historical boundaries in vertebrate biology, the subject is of broad enough importance to catch the interest of a wide audience of readers if I have done my job well. For ex ample, of the major epochal transitions or events there have been in vertebrate history, three come immediately to mind: (1) The transition from aquatic to aerial respiration which ultimately led to a broad occupation of terrestrial habitats. (2) The development of endothermy.

Book Description
Underwater Physiology is a collection of papers that deals with the physiologically limiting effects of undersea, high pressure exposure ranging from fundamental biological reactions, through integration of physiological stresses, and to limits actually experienced in deep diving. Papers discuss oxygen, the mechanisms of toxicity, and the effects of oxygen on cells and systems such as its pathological and physiological influences in the neurosensory ocular tissue. Other papers discuss the physical effects of pressure and gases on cellular function, protein structure, and the possibility of alleviating symptoms through the administration of drugs. Tests in mice show that various gases exhibit qualitative and semi-quantitative differences in the characteristics of sickness, reactions to hypoxia, and the time before the onset of symptoms. A computer, programmed for nonlinear gas transfer and other variables, running in real time can compute directly from the breathing mixture and provide a real time solution to decompression sickness under various conditions. A combined therapeutic approach, recompression and dextran (an effective lipemic clearing agent) should be capable of treating decompression sickness in humans. Other papers investigate the influence of inert gases and pressure on the central nervous system, as well as, situations in undersea and manned chamber operations. This collection can prove valuable for physiologists, biochemists, cellular biologists, and researchers involved in deep sea diving.
