title: Tachypnea and hypocapnia are induced by 'buffeting' in vehicles.
abstract: Normal physiological responses to vehicular buffeting were studied during a 5 minute mild 'off road' exposure in a motion simulator. The ride provoked an initial increase in heart rate and blood pressure and a significant hypocapnia of P(ET) CO(2) 34 mm Hg caused by tachypnea, which took 5 minutes to recover. Motion induced hypocapnia could be a source of distress for vulnerable subjects and patients when travelling.
