An unusual case of obstructive pulmonary oedema.

A four-year-old boy was admitted to intensive care via casualty having suffered an apnoeic episode due to compression of his chest by a heavy cattle bar. A petechial rash was noted on the upper chest and arms. A chest radiograph showed pulmonary oedema which resolved over a few hours following positive pressure ventilation and positive end expiratory pressure. We believe this to be an unusual presentation of obstructive pulmonary oedemia (Negative Pressure Pulmonary Oedema).
