ABSTRACT
Pulmonary oedema occurs when uid passes from the pulmonary capillaries to accumulate in the pulmonary alveoli and causes eects similar to those of the drowning syndromes (see Chapters 21 to 24).
ere are three forms of immersion pulmonary oedema (IPE), induced while swimming, free diving or scuba diving. ey have some similar features, but there are signicant dierences in their demographics, causation and therapeutic implications. e swimming-induced cases tend to occur in persons who are young and very t, but exposed to extreme exertion. e free divers experience breath-holding and barotraumatic inuences that are described elsewhere (see Chapters 3, 6 and 61).
