Title: [abstract] RADIOGRAPHIC MANIFESTATIONS OF EXPERIMENTAL RESPIRATORY DECOMPRESSION SICKNESS IN SHEEP.
Author: Beck, KA; Lehner, CE; Atkins, CE; Dubielzig, RR; Lanphier, EH
Abstract: A potentially fatal syndrome of respiratory decompression sickness (chokes) has long been recognized in divers and caisson workers. Simulated dives at 2.27 ATA (43 ft. of sea water) for 22 h followed by ascent to surface and then 8000 ft. altitude (570 mm Hg) produced a similar syndrome in 17 of 18 sheep. Thoracic radiography was performed on 9 of these 18 sheep both prior to simulated diving and after ascent. Significant correlations exist between rank grades of clinical signs, radiographic and pathologic findings and pulmonary artery bubbles detected by Doppler ultrasound. Six of 9 sheep had radiographic abnormalities with the results listed below. Grade # Radiographic Findings # of Sheep 1 No visible lesions 3/9 2 Questionable t interstitial markings 1/9 3 Mild (but definite) t interstitial markings 2/9 4 Severe t interstitial markings 1/9 5 Patchy alveolar densities and pleural effusion 2/9 These findings are typical of pulmonary edema and correspond to lesions seen in known cases of pulmonary air embolism from a variety of causes.
