Preservation of spontaneous breathing during mechanical ventilation favors the distribution of gas to which areas of the lung?

Question

Quizplus · Accepted Answer

The distribution of gas during spontaneous ventilation favors the dependent lung areas and also appears to favor the periphery of the lung closest to the moving pleural surfaces.The peripheral areas receive more ventilation than the central areas.However,during a positive pressure breath with passive inflation of the lung (paralysis),the central,upper airway,or peribronchial portions of the lung are preferentially filled with air.
