'Zamboni disease'. Pulmonary edema in an ice hockey player.

A 17-year-old previously well ice hockey player experienced acute shortness of breath and cough productive of clear frothy sputum about 1.5 hours following an ice hockey match. Noncardiogenic pulmonary edema was found to develop as a result of the inhalation of the oxides of nitrogen. The latter was produced by a Zamboni machine that is used to resurface the ice on a rink. Several other players were affected but less severely.
