Title Hyperventilation following a large-scale hazardous-materials incident
Bibliographic information July-Sep. 1999, Vol.5, No.3, p.194-197. 17 ref.
Abstract Actual or perceived exposure to hazardous materials may result in physiological and psychological effects. However, hyperventilation following such exposures has not previously been reported. After a large-scale industrial release of oxides of nitrogen, five of 17 patients evaluated at a major trauma center were hyperventilating, as defined by arterial PCO2 < 33mm Hg, and nine patients had arterial PCO2 < 37mm Hg. First responders (rescue team members and paramedics) had a higher rate of hyperventilation than other occupational groups. Age, sex, marital status, decontamination and mode of arrival were not significantly associated with hyperventilation, although marital status was close to being significant. This study suggests that hyperventilation may be a common reaction after hazardous-materials incidents, and that certain populations may be at increased risk for this condition.
