RESPIRATOR HAVING IMPROVED SYNCHRONICITY DURING THE TRANSITION FROM EXPIRATORY TO INSPIRATORY OPERATION

摘要

A respirator for the at least supportive respiration of living beings includes a connection formation for connection to a breathing gas supply, a breathing gas conduit arrangement, pressure change arrangement for changing the pressure in the breathing gas conduit arrangement a flow sensor, which provides a flow signal representing a breathing gas volume flow in the breathing gas conduit arrangement, and a control unit controlling the operation of the respirator. The control unit is configured to trigger a transition from an expiratory to an inspiratory operation of the respirator whenever an increase in the steepness of a flow signal curve exceeds a steepness change threshold value.
