An object lodged in the trachea increases airway resistance predominantly on inspiration.
True
False
This statement is false because an object lodged in the trachea increases airway resistance predominantly during expiration, not inspiration. During an obstructive event in the trachea, such as with a foreign body, air can typically enter the lungs during inspiration when the airway pressure decreases. However, the obstruction prevents air from exiting efficiently during expiration when airway pressure increases, leading to a build-up of air and potential hyperinflation or barotrauma.
