[High frequency pulsation (HFP) enabling tracheo-broncheal suctioning without interrupting mechanical ventilation].

: A new technique of tracheo-broncheal suctioning is presented which enables constant artificial ventilation with high frequency pulsation (HFP), a modification of high frequency ventilation. Beyond that the high frequency pulsation method permits ventilation of the patient with adjusted end-expiratory pressure. This technique prevents the decrease of arterial oxygen pressure which is usually seen in patients who are disconnected for some time from the respirator as well as during the suction procedure and during periods of decreased end-expiratory pressures.
