Abstract
SUMMARY Embolism due to changes in barometric pressure can occur in both aviators and divers. AGE occurs as a result of overpressurization of the lung during an ascent from a dive in which the egress of air from the lung or from a subsection of the lung is prevented. VGE results from local tissue supersaturation and entry of bubbles into tissue capillaries. The vast majority of VGEs are clinically silent, although they can be detected using Doppler or two-dimensional echocardiography. Patients with AGE or symptomatic VGE should be given as high a concentration of inspired O2 as possible and, if possible, transported immediately to a hyperbaric facility.
