Rapid, shallow ventilatory pattern during exercise after histamine, bronchopprovocation.
The ventilatory response to inhaled histamine sufficient to double specific airway resistance was studied at rest and with exercise in normal subjects. There were no ventilatory alterations at rest but during steady-state exercise the subjects adopted a rapid, shallow breathing pattern. Despite this change and increased resistance over-all ventilation and oxygen consumption were unchanged.
