“…[5][6][7] Intrapulmonary percussive ventilation (IPV) derives from high-frequency percussive ventilation, which was initially applied to treat respiratory failure after smoke inhalation or burns. [8][9][10][11] It is a pressure-limited, time-cycled, high-frequency mode of ventilation that delivers sub-physiologic tidal volumes. Since its emergence, IPV has been progressively used in patients affected by excessive respiratory secretions or to treat atelectasis.…”
