First printed in 1983, this book concerns the comparative physiological
adaptations of vertebrate animals, especially mammals, to cessation of
breathing. These adaptations were originally identified in species
living in aquatic habitats. The argument is presented that the natural
divers display a well-developed and conveniently studied example of a
more general defence against asphyxia. The topics considered include the
diving response, metabolic and cardiovascular adaptations, variations in
resistance to asphyxia, neural control mechanisms, which govern the
respiratory and circulatory responses, perinatal asphyxia, applications
to the human species and medical implications. The book's purpose is to
acquaint its readers with some advances resulting from research in this
field.
