Pendelluft phenomenon. Variation of impedance (∆Z) and airway pressure in assisted and controlled mechanical ventilation (PAW). Blue line: posterior region of lung. Red line: Anterior region of lung. In assisted mechanical ventilation, anterior region of lung decreases its impedance variation (loses air) and at the same time posterior region increases (being aerated).
